DataCore Storage Virtualization Software Delivers 100% Uptime to iomart hosting

http://www.dabcc.com/article.aspx?id=13727
iomart hosting, one of the UK's fastest growing managed services providers, is using DataCore's SANsymphony™ solution to provide the high-availability backbone for iomart's hosted customers.

Richard McMahon is the company's Infrastructure Manager responsible for all hardware and software deployments and services within the group. Twenty-five people operate from within iomart's five (5) state-of-the-art data centers located in London, Maidenhead, Glasgow, Nottingham and Leicester. All centers are linked via Dark Fibre or GigE connections.
"Our 100% uptime guarantee is not a marketing ploy - it's iomart's motto and mantra. We live and breathe it to facilitate our customers' business models. Therefore total high-availability is top of our priority list," he stated.

Recently, to help clients facilitate cloud computing, iomart launched a dedicated, virtualized server service, offering VMware dedicated servers capable of running multiple operating systems and applications from one physical server.

With these services in mind, the challenge that iomart faced was managing 30 terabytes (TBs) of storage across a heterogeneous environment in the City of London and Maidenhead data centers. To meet this objective, iomart approached DataCore, EMC, NetApp and 3PAR for proposed solutions. The suggested environment from DataCore involved using standard x86 hardware, highly specified due to their being of a hosting nature, each having 128GB RAM for caching, 4 Quad Core Processors and 8GB HBA's for connectivity. The disk that sat behind the server was classified as a low-end commodity disk. On top of this hardware, DataCore's SANsymphony solution was used in a mirrored SAN-SAN configuration to virtualize and manage the environment across a fibre link. In total, the solution was less than a one-third of the cost of the equivalent software and hardware alternative proposals.

Keith Joseph, Regional Manager, DataCore Software picks up the story: "Cost savings were not the most important factor in iomart's search. What they really wanted was to achieve total control of the environment and have the ability to migrate customer data between storage systems and disk types and to easily replicate to remote sites. This they found with DataCore's SANsymphony."

Mirrored high-availability (HA) between sites over 20 miles away also provides iomart with enhanced disaster recover (DR) capabilities. In their configuration, the environment is distributed throughout several locations and ensures that they have a fully distributed, HA model but across DR geographies.

DataCore's synchronous replication functionality operates on a forced cache coherency model, based on a grid architecture that replicates the I/O block between the cache on each DataCore server before sending the acknowledgement to the application server and committing the data to disk. This overcomes the problems associated with clustered storage, while allowing iomart a greater degree of performance and flexibility.

McMahon concludes, "What we have achieved with SANsymphony is totally flexible, highly performing SAN-to-SAN mirroring, but straight out-of-the-box and backed by a decent price point. We can now move data 'at will' between vendors and seamlessly achieve LUN virtualisation across RAID arrays. No other solution offers us this."

Virginia's Dinwiddie County Government Deploys DataCore Storage Virtualization to Empower VMware

Computer Technology Review:
To read the complete story, please visit: http://www.wwpi.com/index.php?option=com_content&view=article&catid=229:virtualization&id=8351:virginias-dinwiddie-county-government-deploys-datacore-storage-virtualization-to-empower-vmware&Itemid=2701140

DataCore Software has been deployed along with VMware vSphere for the government of Dinwiddie County in Virginia. "We were convinced that we needed a SAN to support our objective of server consolidation with VMware as well as our desire to achieve uptime," explained Norman Cohen, IT Director, Dinwiddie County Government. "We are so impressed with the new virtualization environment and DataCore's role as the virtual storage dimension to everything that we are actively encouraging other county governments in our state to do what we have done in our VMware-DataCore deployment."

"DataCore's storage virtualization software solution has allowed us to springboard into the world of virtualization – particularly enabling us to leverage the benefits of VMware," noted Cohen. "The most important component of our virtualization deployment has to do with virtualizing our disks with DataCore. We can now utilize disk space – no matter where those disks reside on campus. But storage virtualization does so much more than delivering shared storage by way of pooling disks. With DataCore, our IT environment has attained high-availability and fault-tolerance, by way of the remote replication that is made possible by the two DataCore-powered SANs."

Virtualization should be 3D: DataCore


Virtualization should be 3D: DataCore
http://www.itworldcanada.com/news/virtualization-should-be-3d-datacore/140005-pg1

DataCore Software is evangelizing a virtualization strategy that entails server, desktop and storage concurrently from the outset to avoid performance bottlenecks. IDC’s Dave Pearson calls storage virtualization the “support” technology

Storage technology vendor DataCore Software Corp. is touting a three-dimensional approach to virtualization that encourages organizations to address server, desktop and storage concurrently from the outset when building a virtualized environment.

Augie Gonzalez, director of product marketing with the Fort Lauderdale, Fla.-based company, said focusing on just server and desktop at the beginning while neglecting storage will lead to negative consequences in the long run.

“Leaving out any one of those dimensions creates shortcomings and obstacles for that customer downstream,” said Gonzalez.

The number of dependencies on the storage infrastructure are magnified with server and desktop virtualization, said Gonzales. Specifically, performance bottlenecks occur when desktops and servers are consolidated and an increased number of inputs and outputs are driven against the storage pool, he explained.

Gonzalez said problems encountered down the road due to bad planning are one reason IT departments hesitate to move Tier 1 workloads to a virtual environment. “As soon as they scale out to actually meet the workload demand, that’s when they hit upon it … and that’s when people start to rethink whether they were doing the right thing by virtualizing,” said Gonzales.

According to Dave Pearson, senior analyst for storage at Toronto-based IDC Canada Ltd., storage virtualization is a relatively new, albeit key, component of virtualization. But he said the storage component is still a “support” technology led in most cases by server virtualization.

Pearson said storage virtualization forms part of what he calls "virtualization 3.0," where it’s not just about getting rid of physical machines and improving processes anymore. “It’s now part of optimizing the entire solution, making sure you’re really getting your money’s worth out of the hardware that you’re committing to these virtualization projects,” he said.

However, while Pearson agrees storage is a vital component of an organization’s virtualization strategy, he said such a 3D approach is hardly a novel idea to IT pros involved in large virtualization projects.

The 3D approach is “just really another tool that’s being added to the box of tools for virtualization,” said Pearson. Besides DataCore, Fremont, Calif.-based 3PAR Inc., among others, is in the market.

DataCore is relying on its community of resellers to evangelize this 3D virtualization approach because, according to Gonzales, customers still require a lot of education on the topic.

Gonzales said the “second phase of adoption” of virtualization to areas like business continuity, risk mitigation and disaster recovery, is beginning to shine a spotlight on storage. “All of those many machines and many users and many virtual workloads now become so centred on how the storage environment behaves and how well that virtual view of storage remains intact as you move through generations of hardware,” he said.

Pearson said storage virtualization is growing more quickly in importance than server virtualization, but not at the same level overall.

Video: Storage Virtualization and DataCore (Jon Toigo Interviews Ziya Aral)


Video: Storage Virtualization and DataCore (Click on link below for Video Interview)
http://esj.com/articles/2010/02/16/video-datacore-storage-virt.aspx?sc_lang=en

Ziya Aral , CTO and co-founder of Ft. Lauderdale, FL-based storage virtualization software vendor, DataCore Software, offers an analysis of server and storage virtualization that blows the socks off of the marketspeak one usually hears or reads from industry analysts and vendors. That's because he has been part of the evolution of the technology over the past three decades.

Says Aral, in this interview recorded for the C-4 Summit Cyberspace Edition, virtualization was -- and is -- inevitable. He notes that embedding software on hardware became a costly and inefficient design choice years ago -- especially as hardware architecture became more standardized. Software complexity required its migration to a computer so it could be maintained and improved without requiring the costly replacement of the underlying hardware platform.

He argues that DataCore's key innovation was to conceive of the "storage application" as any other computer application, separating it from the storage hardware layer -- the costly and complex value-add array controller. The benefits of such abstracting storage services into a virtualization layer would be to deliver a rich set of services that could be applied across hardware without concern for the vendor badging of the hardware itself. Software and hardware could scale independently.

Performance and management also improve with virtualization, Aral notes, citing the success of DataCore customers for proof. To hear the rest of Aral's fascinating analysis, check out the C-4 Project (http://www.c4project.org/ ), where Aral is part of an on-going "summit in cyberspace."

10 Ways To Add Value To Virtual Environments; ''Virtualization in 3-D' and DataCore

10 Ways To Add Value To Virtual Environments [slide show]
http://www.crn.com/hardware/223100199;jsessionid=KRTE4R2ONXQ2BQE1GHPCKH4ATMY32JVN?pgno=7
VMware held its annual VMware Partner Exchange earlier this month, and used the conference to talk about virtualization and cloud computing.

DataCore: Virtualization In 3-D
DataCore, Ft. Lauderdale, Fla., used the conference less to talk about products and more to discuss its central theme for 2010, "Virtualization in 3-D."

Storage virtualization is the third dimension after server and desktop virtualization, according to DataCore, which also said that the fundamentals of a virtualization solution are not adequately addressed until the software tackles storage-related challenges.

Augie Gonzalez , director of product marketing at DataCore, said that, while servers and desktops deserve much attention, disks represent a constant source of upheaval in virtual environments.

He also said DataCore lets customers provision, share, reconfigure, migrate, replicate, expand, and upgrade storage without impacting production environments, and virtualizes disks across pools of tiered storage devices to overcome incompatibilities between different generations, models, and manufacturers of storage devices.


VMware Partner Exchange 2010 closes with VMware Solution Providers heralding DataCore Software as the 3rd dimension to their virtualisation practice.

Creating DMZs in the Cloud

http://www.ctoedge.com/content/creating-dmzs-cloud
One of the things being heavily pitched toward anybody building a cloud computing service these days is the value of highly integrated servers. The thinking goes that the higher the level of integration, the lower the cost to maintain and run the system.

But there is another argument that speaks to the need to isolate specific sets of services inside a larger cloud computing service. For example, if you go with an integrated server, you pretty much have to move in lockstep with that vendor for all your servers, networking and storage. If there is a major advance in any one of these areas, a chief technologist running a cloud computing service on an integrated server might not be able to take advantage of it until the vendor upgrades the entire system. Given the long-term nature of cloud computing services and the level of cut-throat competition, that might not be the strategic way to go.

Instead, vendors such as DataCore Software, a provider of storage virtualization software, argue that cloud computing services should, for example, isolate services like storage using a software-only approach that makes it realtively easy to create pools of storage by mixing and matching storage hardware from multiple vendors. This approach helps creates a “demilitarized zone” between technologies that allow IT organizations to continue to leverage multile vendors to take advantage of ongoing advances in technology.

According to Augie Gonzalez, DataCore Software director of product marketing, this approach also provides the ability to leverage inexpensive cache on the server to drive performance, versus relying on limited amounts of expensive cache on the storage arrays. Gonzalez also points out that as software offering, DataCore can offer the same level of integration with cloud computing offerings such as Cisco Nexus virtual switches and VMware’s vSphere management software.

So all things being equal, the question becomes is it worth mortgaging the future to gain some short term gains in system administration that can probably be achieved anyway without locking in the hardware?

Jon Toigo excerpt on storage virtualization

On to a New Decade

In 2010, vendor marketing campaigns will ramp up with the usual hype.
By Jon William Toigo - Feb 2010
http://esj.com/Articles/2010/02/02/Storage-New-Decade.aspx?Page=1

Interestingly, server virtualization has breathed new life into storage virtualization -- resurrecting the technology from the rubble of the late 1990s tech industry meltdown and driving it into the mainstream.

Server virtualization claims to optimize CPU and memory resources in commodity servers by separating the application software (and in some cases the operating system) layer from the underlying hardware platform, then inserting a hypervisor of some intelligence into the allocation of hardware resources to apps. Storage virtualization takes a similar tack: a storage virtualization software layer abstracts the "value-add" software functionality from storage array controllers and places it into a software layer.

The fundamental merit of this approach, which has crystallized in products from DataCore, FalconStor Software and a few others, is that it enables value-add software functions to be applied across all connected storage hardware, regardless of the brand name on each box. That helps to eliminate consumer lock-ins to proprietary storage vendor rigs and to save big on current on-array software licensing fees.

In the latest developments, DataCore Software has set new industry records by creating stable virtual volumes from commodity disk of a petabyte or greater in size. Their Advanced Site Recovery...are enabling data protection to reach a new level without the associated cost of requiring identical name-brand equipment at your production and disaster recovery environments.

Storage virtualization makes enormous sense from a resource efficiency perspective as well as a cost perspective. By establishing value-add functionality in a software layer that scales independently of hardware, hardware vendors can focus on improving the speeds and feeds of their rigs without concerning themselves with maintaining a complex set of software functions that tend to break more often than the hardware.

Host.net combines DataCore Software, VMware and Cisco to provide new cloud computing platform

Link: Host.net’s Cloud Computing – Enterprise Virtual Solutions Overview



Search Storage: Host.net combines DataCore Software, VMware and Cisco to provide new cloud computing platform

DataCore Software announced that its storage virtualization technology is helping to power a cloud computing platform by Host.net. The Host.net platform also includes VMware server virtualization and Cisco Nexus virtual network technologies. With this platform, private clouds can be built on virtual servers from VMware vSphere, Cisco and DataCore storage virtualization. Each virtualization technology comes with different capabilities such as converged networking from Cisco, synchronous mirroring from DataCore and the ability to quickly grow storage from VMware.
http://searchdisasterrecovery.techtarget.com/news/article/0,289142,sid190_gci1379793,00.html#

“We chose VMware, DataCore and Cisco in the core design of our cloud platform because each vendor delivers the very best virtualization component in their respective areas of competence,” said Jeffrey Slapp, VP of Virtualization Services for Host.net. “In three months’ time, dozens of companies have signed on as new customers because of the competitive advantages we have achieved with this combination of technologies and architecture.”

Cloud Agility through Hardware Independence

“It seems to me that any cloud computing platform needs to, at its very core, be based on portable software,” stated George Teixeira, President and CEO, DataCore Software. “Many clouds are being built from a hardware vendor-specific mindset. What is wrong with this picture? Well, the whole point of cloud computing is delivering cost-effective services to users – and that demands the highest degree of flexibility and openness, versus being boxed in to specific hardware platforms that may not adapt to changes over time. Aren’t clouds, after all, supposed to be soft and agile?”

Because the Host.net vPDC platform is comprised of software-based technologies, the company’s offering is not tied to any specific hardware. This avoids the problems associated with building clouds with a hardware provider sandwiched between virtual servers and virtual networks, enabling flexibility far beyond any cloud offering dependent on hardware vendors like IBM, EMC and NetApp. It also essentially eliminates any capital expenditure outlays from the customer.

“With or without a recession, companies are looking for cost-effective infrastructure solutions. A software-based cloud architecture helps answer that need,” said Lenny Chesal, Executive Vice President of Host.net. “This makes it a direct, positive impact on the customer’s bottom line as well as overall efficiency, enabling companies to do more with less.”

VMware Solution Providers herald DataCore Software as the 3rd dimension to their virtualization practice


DataCore™ storage virtualization software deemed strategic to their Server Virtualisation and Desktop Virtualization business

As the doors closed on last weeks VMware Partner Exchange in Las Vegas, DataCore Software assessed the strategic value that its storage virtualization software brings to VMware solution providers. Simply put, DataCore fulfills the 3rd dimension required by VMware value- added resellers (VARs), service and hosting providers to complete their virtualization offerings. “Failing to include storage virtualization software to address IT storage challenges results in an incomplete, two-dimensional solution,” comments Augie Gonzalez, Director of Product Marketing, DataCore Software. “Virtualization solutions must concurrently address server, desktop and storage challenges presented by the many variations of hardware that get deployed over the course of multiple years.”

With DataCore storage virtualization software, VMware customers gain storage hardware flexibility and improved disk space utilization. Importantly, VMware users do not have to spend a lot of time and money ripping out and replacing perfectly good disks to set up a shared storage infrastructure. DataCore Software enables solution providers to easily repurpose their customers’ existing hardware into a highly-available storage network that supports VMware features like VMotion and remote site disaster recovery (DR) – perfectly complementing their virtual servers and desktops with virtualised storage.

Testimonials from VMware VARs

The following testimonials reveal just how important DataCore is to meeting customer needs in virtual IT infrastructures and cloud initiatives.

“Virtualization is a 3-dimensional puzzle,” states Pat Sigg, Regional Vice President of Sales at Software Information Systems (SIS), a VMware partner. “What we consistently find when engaging in virtualisation deployments is – first and foremost – the need to virtualize storage resources with the flexibility, high-availability and performance to support numerous virtual servers and desktops without single points of failure. It is this 3rd dimension to virtualization – the storage virtualization dimension – that DataCore brings to our virtualization practice.”

“As a VMware partner specializing in virtualization solutions, what we have found is that to really get the magic out of VMware, you need DataCore storage virtualization – be that hardware independence as well as just an astonishing degree of flexibility – that combine to literally pave the way for each of our virtualization deployments to perform as promised,” comments Chuck Renfro, CEO, ThinkingCap Technologies, LLC. “The bottom-line is that DataCore is vital in enabling our virtualization customers to meet their business objectives – chief among which is realizing high-availability.”

“Virtualization projects are three-dimensional,” explains Andy Judge, Founder and CEO of Grove Networks, a VMware Enterprise Partner. “Server and desktop virtualization software address two of those dimensions. DataCore storage virtualization software is as important, financially and operationally, to a successful virtual infrastructure project as are the server and desktop virtualization aspects.”

Virtualizing Storage in the Cloud: “Priority One”

Any cloud computing platform, just like any virtualization deployment, needs to have portable software as its building blocks – providing the highest degree of flexibility and openness. DataCore partner Host.net knows intuitively that storage virtualization software is priority one.

“We chose DataCore in the core design of our virtual private data center (vPDC) platform alongside VMware and Cisco because it delivers the very best storage virtualization component,” notes Jeffrey Slapp, Vice President of Virtualization Services for Host.net. “Virtualizing the storage is paramount to us for two reasons. First, we required a solution that would allow us to expand storage resources rapidly and non-disruptively to meet increasing demand. Second, we needed a solution that could leverage various hardware storage platforms simultaneously in order to keep pace with technology changes. Accomplishing both allows us to provide high-end enterprise-level services while remaining agile and cost-effective.”

VMware Partner Exchange 2010 ran from February 8 -11 at the Mandalay Bay Convention Center in Las Vegas.

Virtualization Powers Mission-Critical Applications; North American Stainless Deploys DataCore Storage Virtualization Software with VMware

VMware vSphere and DataCore Software's Storage Virtualization Are Making Both Disaster Recovery Possible at One of North America's Largest Stainless Steel Manufacturers
http://www.dabcc.com/article.aspx?id=13237
http://www.datastorageconnection.com/article.mvc/North-American-Stainless-Deploys-DataCore-0001?VNETCOOKIE=NO

DataCore SANmelody storage virtualization solution has been deployed along with VMware vSphere at one of the world's premiere providers of stainless steel - North American Stainless in Ghent, Kentucky. The company's IT department was trying to cope with an already increasing server spiral that encompassed ten (10) servers - all of which were over five years old. "We felt VMware would give us more options than simply adding more physical servers," stated Judy Pieper-Young, Manager - Information Systems, North American Stainless. "Now with VMware combined with DataCore, we can simply add more virtual machines on-the-fly and it only costs us a new server license - instead of having to purchase a whole new physical box."

A Virtual Infrastructure That Delivers Value as Promised
The IT landscape has gone a diet, so to speak, since the advent of virtualization at North American Stainless. Today, the company relies on four (4) physical servers and 35 virtual machines (VMs). The system supports 1,400 end-users.

"The appeal for us in going virtual in terms of servers was straightforward," explained Pieper-Young. "Knowing that we were facing a situation where we were in need of adding even more servers – we chose to embrace virtualization so that we could actually reduce the number of physical servers. But we did not want to stop at servers. In order to achieve a completely virtual infrastructure, we selected DataCore along with VMware to serve as a total virtual infrastructure spanning both servers and storage."

North American Stainless manufactures stainless steel 24 hours a day, seven days a week, and 365 days a year. Therefore, beyond an initial desire to add more capacity by adding virtual storage to the mix was an overarching objective to have a disaster recovery plan in place. For disaster recovery, the company now has two SANmelody nodes that are mirrored so as to offer synchronous replication. "If for any reason we have a server crash, the virtual infrastructure enables us to get up and running within seconds," noted Pieper-Young.

The two, redundant SANmelody SANs that are mirrored are connected to redundant switches that are in turn connected to four VMware ESX hosts, to remove any single point of failure. Now North American Stainless has redundant, high-availability SANs that are synchronous – connected with a direct-attached fibre link. With this in place, the company can withstand a full hardware failure at a server level, at a switch level as well as a SAN level and still be up and running, in production. Other than a facility failure, North American Stainless now has 100% uptime.

The IT Landscape – Virtualization Powers Mission-Critical Applications

The virtual infrastructure powered by VMware and DataCore supports the company's Oracle ERP system servers (including payroll), several SQL servers, Blackberry® server, fax servers, print servers as well as user data. The ability to add VMs "on-the-fly" was a primary objective in going virtual. This is made possible through the combination of VMware vSphere's live migration functionality and the DataCore SAN. With VMware and DataCore run in tandem, the IT team at North American Stainless is able to do testing on applications and do so in way that the any testing procedures for new applications are segmented from the overall system. This is accomplished with DataCore SANmelody serving as a complete virtual storage infrastructure and storage management system – whereby multiple terabytes of storage can be both partitioned in units for a specific use as well as aggregated for general consumption.

Both SANmelody nodes are running on IBM 3650 servers as are the VMs on the two additional servers.

Advanced Site Recovery Described - DataCore Software

http://www.channelprosmb.com/article/15736/DataCore-Software-Adds-Advanced-Site-Recovery-ASR-Option-for-SANmelody/

New option will better address business continuity and disaster recovery needs of remote and branch offices.

Fort Laudedale, Fla.-based DataCore Software, a provider of storage virtualization, business continuity, and disaster recovery software solutions, is kicking off the new year by launching an Advanced Site Recovery (ASR) solution for SANmelody. The software is designed to work across both virtual and physical storage infrastructures to eliminate or minimize business disruptions and data loss attributed to planned and unforeseen site outages and disasters.

ASR was first developed around SANsymphony to enable larger data centers and organizations to simplify remote site recovery while leveraging readily available IT assets between different sites. In releasing ASR for SANmelody, DataCore is providing a more cost-effective solution for smaller businesses and remote site deployments.

ASR makes distributed disaster recovery (D-DR) flexibility more practical for all organizations, thereby opening the field of users to smaller businesses. ASR can be tailored to whatever a company's cost structure allows.

"With ASR, DataCore has developed a distributed and cost-effective way to have IT assets at remote offices and branch offices (ROBOs) take over for the main data center when the central machines are unable to meet processing obligations," explains Augie Gonzalez, director of product marketing, DataCore Software. "Whether that is during planned facility outage or an unexpected disaster makes no difference. There are major cost savings from repurposing ROBO IT assets and personnel for business continuity."

ASR for SANmelody builds on DataCore's universal storage virtualization software to move IT operations from a central site to one (or more) distributed contingency locations--and back again. While SANmelody ASR can be used between two sites, the far more likely scenario is a "hub and spoke" model in which a SANsymphony ASR license will be used in the central site, with connections to multiple remote offices/branch offices running SANmelody ASR.

This solution allows organizations to spread DR responsibilities across several smaller sites. Additionally, the solution makes no distinction between physical and virtual servers, unifying their DR operations in a common, automated process. And, ASR for SANmelody does not depend on duplicating equipment offsite, such as disk arrays and specialized networking gear.

Storage virtualization from DataCore adds support for logical volumes up to 1 PB and the Asymmetric Logical Unit Access (ALUA) standard

http://itknowledgeexchange.techtarget.com/storage-soup/datacore-adds-support-for-logical-volumes-up-to-1-pb/

DataCore kicked off 2010 with updates to its SANSymphony and SANMelody storage virtualization software, adding support for logical volumes up to 1 PB and the Asymmetric Logical Unit Access (ALUA) standard...

DataCore director of product marketing Augie Gonzalez said that as with last year’s 1 TB “mega-cache” support, the logical limit is beyond where most customers will be looking to stretch today. But the previous 2 TB limit had grown impractical for making RAID sets out of the latest 1 TB and 2 TB SATA disks.

“The logical volume expansion and thin provisioning allows users to say, ‘I don’t care how big the volume will be in the future’,” Gonzalez said. “Rather than defining LUNs up front and then having to make changes later, you can immediately set up a large volume and expand the storage with no applicvation or infrastructure changes.”

A DataCore service provider customers says adding ALUA support will improve management in his storage environment. Joseph Stedler, director of data center engineering for cloud computing and managed IT service provider OS33, said he uses DataCore’s SANSymphony software to host back-end storage for his SMB customers. Right now SANSymphony is running on IBM System x servers in front of IBM DS3400 arrays and Xiotech Emprise 5000 storage devices, mirroring between redundant sets of the tiered hardware. The logical volume expansion will be especially helpful in cutting down on backup administration overhead, Stedler said.

“With two terabyte volumes, we had to present things in 2 terabyte chunks to our Veeam [backup] server,” he said. “With a larger primary volume we could have fewer backup targets to manage.”

Stedler said the addition of ALUA support will be even more important for creating multipath I/O in OS33’s VMware environment. “ALUA solves a major pain for everybody running DataCore with VMware,” he said. “The way VMware understood it before was active-passive only. DataCore was able to do active-active failover but with VMware you’d have to run multipathing with the most recently used path. The new release is fully compliant with ALUA, so VMware can view it as active-active.”

Stedler said he’s looking forward to the addition of more granular scripting capabilities for the software in future releases.

Virtualization Predictions: Desktop and Storage Virtualization are the next "Big Wave"

David Marshall from Infoworld/VMblog has posted a series of interviews on 2010 predictions.
DataCore and 2 DataCore solution providers - Helixstorm and Mirazon Group share their outlook on 2010 trends. Read the full article at:

http://vmblog.com/archive/2009/12/31/desktop-and-storage-virtualization-are-the-next-big-wave.aspx

Desktop and Storage Virtualization are the next "big wave"

DataCore Software's CEO George Teixeira shares his viewpoint on 2010. Plus, representatives from two DataCore solution advisor partners weigh in on what they see coming in the virtualization space in 2010.

George Teixeira - President & CEO of DataCore Software

Prediction: Consolidation was the driver of the first wave of virtualization. In 2010, both storage and desktop virtualization will go mainstream.

Prediction: The growing cost disparity between Hypervisors and traditional SANs and shared storage arrays, needed to support virtual infrastructures, will slow down the pace of virtualization adoption.

Prediction: Microsoft Hyper-V has created another wave - the whole Microsoft world -that is embracing virtualization and this trend will continue to accelerate in 2010.

Prediction: This will be the year of virtual desktop proof of concepts (POCs) and pilots; greatest challenge to success is overcoming the cost of storage and the ability to scale storage effectively.

Prediction: Because virtual servers are starting to become a commodity - this puts even more importance on getting the storage piece right.

Clouds and Virtual Infrastructures - DataCore Solution Provider the Mirazon Group Predicts Virtualization in 2010

David Marshall from Infoworld/VMblog has posted interviews on 2010 predictions.
This is a post from DataCore solution provider Mirazon Group.
Check out the full article:

Desktop and Storage Virtualization are the Next "Big Wave"
http://vmblog.com/archive/2009/12/31/desktop-and-storage-virtualization-are-the-next-big-wave.aspx

Clouds and Virtual Infrastructures

Craig Stein - Systems Architect for The Mirazon Group

Clouds and Virtual Infrastructures (not just virtual servers) that encompass virtual storage and VDI are the major opportunities for 2010:

1. The Cloud Computing concept will become more of a reality as service providers offer easy ways for customers to embrace the portability of their virtual workloads to move their VMs and storage from private clouds to hosted cloud infrastructures and back as needed.

2. Greater adoption of Microsoft Hyper-V R2 in both SMB and Enterprise markets for both development and production environments.

3. As organizations embrace Hyper-V we expect to see more products that support the backup and management of vSphere/ESX to also support the Hyper-V platform.

4. As IT budgets are cut, we expect to see a greater trend towards Storage Virtualization that allows commoditization of storage and a heterogeneous vendor approach - instead of a single vendor solution that locks the customer into their initial storage vendor.

5. We expect the VDI market will slowly yield solutions with lower CAPEX cost of Virtual Desktops. VDI is still very expensive from the Software/Thin Client/Storage (SAN) perspective. The ROI for VDI is currently realized through reduced OPEX costs. OPEX costs will also continue to improve as better management tools appear and the VDI software matures.

6. More and more organizations will realize the value of Virtualization as it relates to Disaster Recovery. Even small businesses are embracing Virtualization as the technology becomes more mainstream - simply for the recoverability.

7. In 2010, we expect the trend to continue where Application Vendors embrace virtualization of all workloads, including I/O intensive servers running SQL, Oracle, Exchange as the technology is understood, proven and trusted by the ISVs.

8. For Telephone/Communication systems, as SIP Trunks become more popular in replacing proprietary T1/E1 cards, we expect to see virtualization of voice platforms for increased uptime and DR that virtualization affords.

Desktop and Storage Virtualization are the Next "Big Wave"
http://vmblog.com/archive/2009/12/31/desktop-and-storage-virtualization-are-the-next-big-wave.aspx

Virtualizing Desktops and Storage

Aaron Schneider - Director of Sales Engineering for Helixstorm, Inc.

Virtual servers and consolidation drove the first wave.

Aggregating compute resources through virtualization is now a black and white cost-savings value proposition. Server virtualization has proven itself by consolidating workloads and reducing hardware, power, cabling, and cooling costs. Many companies have already made the jump into virtualization and have successfully increased their service level agreements (SLAs) and implemented rapid application delivery to deal with ever changing business processes and to better protect their data through business continuity.

So what else can we do with virtualization and clouds?

While server virtualization for consolidation may be somewhat saturated, there are still very large untapped areas where virtualization or cloud computing will make a huge impact. Desktop and storage virtualization will be the next "big wave." There has been plenty of activity/discussions/buzz around adopting desktop computing into the cloud. However, virtualizing the desktop has nowhere near the adoption rate as server virtualization - even though the underlying technologies and concepts are identical. Virtual Desktop Infrastructure (VDI) has historically fallen short in two (2) keys areas - user experience delivery and short term ROI. At the end of the day, there is not a CEO on the planet that will sacrifice a poor user experience on the desktop to make life easier for IT. On the ROI front, there is a significant investment made to adopt desktop virtualization (server, storage, software, thin clients), which is why some organizations turn to vendors that offer desktops through SaaS (Software as a Service). However, over time, there is a strong ROI over the traditional desktop. In our opinion, the only true way to implement desktop virtualization is to de-couple the operating system from the applications and then in "real-time" mesh the two together and deliver to the end-user the usability they need. Citrix and VMware have the leading and most stable approaches for these types of implementations right now.

Organizations that have adopted or are looking to adopt server and desktop virtualization need to look strongly at the storage aspect. Virtualizing the storage layer to have a virtual infrastructure is critical. This gives companies the ability to implement Enterprise features to deliver business continuity such as synchronous and asynchronous replication to safeguard corporate information, without the "Enterprise" price tag. This is a key topic, since we find that many companies in the SMB market need the ability to provide Enterprise level features of a traditional storage solution, at a price point that fits their budget. A software approach to storage virtualization, such as that provided by DataCore software, does just that. It protects your software investment while the value of the hardware continues to depreciate on a daily basis.

The virtualization marketplace is still filled with solutions to help you improve and implement business processes. The impact of virtualization is spreading and this year it will lead to greater success for desktop and storage virtualization. In terms of desktops, new technologies like PCoIP (PC over IP) along with advancements in several connection broker technologies look to finally solve the end- user experience and deliver a seamless, near-native desktop computing platform. Storage virtualization as a software solution is breaking down the remaining hardware constraints and continues to evolve so that today it has become amore cost-effective alternative over traditional-based arrays and is doing so without sacrificing performance or features. The key point is that the technology now exists to build virtual infrastructures and clouds, but it has to fit the budgets. Cost-effective storage virtualization solutions are a critical factor to the further growth of both server and desktop adoption in the marketplace.

THE TOP NEWS OF THE DAY
DataCore Super-Sizes Virtual Disks (Up to 1PB)
With its latest storage virtualization software
http://www.storagenewsletter.com/news/software/datacore-super-sizes-virtual-disks

DataCore Software responds to market demands, this time by stretching the size of its virtual disks from 2 Terabytes (TBs) to 1 Petabyte (PB).

“Rather than inch up to 4 or 16 TBs as others are considering, DataCore made the strategic design choice to blow the roof off the capacity ceiling with 1 Petabyte LUNs,” commented Augie Gonzalez, Director of Product Marketing, DataCore Software. “But we’re still frugal on the back-end, using thin-provisioning to minimize how much real capacity has to be in place day one.”

Performance wise, these immense virtual disks benefit from DataCore’s 1 TB per node, 64-bit 'mega-caches.' “You can be big, and very fast too,” added Gonzalez.

DataCore virtual storage area network meets backup, disaster recovery needs for Legal Firm

http://searchservervirtualization.techtarget.com/tip/0,289483,sid94_gci1373949_mem1,00.html?ShortReg=1&mboxConv=searchServerVirtualization_RegActivate_Submit&

With about 3 TB of virtualized server data and another 2 TB of email and database data that needed to be backed up daily, Montreal-based law firm Stikeman Elliott LLP faced a growing problem. Virtual storage area network backups were taking 24 to 48 hours, and not all of the data was getting backed up properly.

What was needed, said Marco Magini, a network system specialist for the firm, was an almost instantaneous backup system. The firm chose DataCore Software Corp.'s SANmelody software, a virtual storage area network (SAN) that's installed on one or two x86 servers. The servers become virtual storage controllers for large arrays of physical and virtual storage disks. Those disks are then moved to existing networks to send data to application servers, according to DataCore.

SANmelody solved several other IT challenges, including disaster recovery shortcomings and high-availability needs for virtualized servers, Magini said. "I was not looking for storage virtualization. We had plenty of storage to fill our needs." But once the application was installed, we uncovered a host of new unexpected capabilities, he said.

Stikeman Elliott started testing SANmelody in June 2008 and then deployed it into production last September. The 1,200-employee law firm is using the product in its Montreal headquarters and will roll it out to six other offices around the globe.

Magini said he's still finding new ways to get performance gains using SANmelody. "We started small," he said. "It's not that you don't have faith in the products, but when you are moving business-critical data, you want to be sure it can handle it."

SANmelody also allowed the IT department to make use of all types of unused legacy disks. When added to the system, SANmelody's management system views them as one massive disk for storage. That allowed Magini to reuse about 50 old 72 GB drives that were sitting on a shelf.

Mark Bowker, an analyst with Enterprise Strategy Group in Milford, Mass., said it's not unusual for a planned server or storage virtualization project to affect other IT needs. "People typically begin projects for something as simple as server consolidation or resource utilization," Bowker said. "But they find other infrastructure is needed. Once they start rolling out virtualization, they find there are other benefits to be had," including disaster recovery and improved backup capabilities.

Northwest Wholesale Florists In Seattle Deploys DataCore Storage Virtualization Software And Microsoft Hyper-V

http://www.datastorageconnection.com/article.mvc/The-Sweet-Smell-Of-Server-And-Storage-0001

"What we have found with the DataCore and Microsoft Windows Server 2008 R2 + Hyper-V combination is a virtual infrastructure that is redundant, reliable, flexible and expandable," stated Mary Toupin, Office Manager, Northwest Wholesale Florists. "Moreover, the redundant storage with DataCore complements the redundancy built into the VM system. We are very pleased with the way the system has performed."

The original desire to upgrade its IT infrastructure was driven by the fact that NWF was moving to a new warehouse – and needed to do that while running operations from the existing warehouse. NWF looked to Moose Logic to design a new IT infrastructure system and provide a smooth transition. In this case, Moose Logic thought that there were a number of benefits in deploying Hyper-V, even before the release of Windows Server 2008 R2. However, after the R2 release of Windows Server 2008, Hyper-V has been infused with live migration functionality – which was not in Hyper-V prior to R2. "As a reseller, the combination of DataCore with Microsoft Windows Server 2008 R2 with Hyper-V gives our firm and this customer a lot of flexibility," commented Scott Gorcester, President, Moose Logic, a solutions provider and DataCore partner in the Pacific Northwest. "Using DataCore storage virtualization combined with Microsoft Windows Server 2008 R2 and Hyper-V in joint configurations is already proving to be a great combination for both resellers and users alike."


Re-purposing Existing Hardware and Deploying Windows Server 2008 R2 with Hyper-V


Knowing that there were two sound pieces of hardware that could be re-purposed, Moose Logic recommended a solution based on Windows Server 2008 R2 running Hyper-V. The firm built the customer two Hyper-V servers with System Center Virtual Machine Manager, running in a failover cluster. Coupled with the clustered pair of Hyper-V servers is a pair of DataCore SANmelody servers – one on an existing HP DL 380 G5 that was repurposed after adding new disk drives and more memory and the other on a new HP DL 380 G5 server to match the existing one. These G5 servers became the SAN nodes. This system went live at the customer's new location on October 1, 2009. Thirty-plus (30+) users benefit from the system daily.

Network Computing Feature: WHY A STORAGE BACKBONE BENEFITS FROM HARDWARE INDEPENDENCE WHEN BUILDING A STORAGE VIRTUALISATION STRATEGY.

http://networkcomputing.co.uk/articles/reviews.asp?a_id=253
From Network Computing Vol 18

Over the past 12 months as the credit crunch has deepened, organisations have sought alternatives from purchasing costly storage hardware. In turn, many have explored the adoption of software virtualisation to enable and optimise their storage. They have understood that software based Storage Area Networks (SAN) offer immediate advantages to the bottom line, invariably meaning that the IT Department can enable the project to progress, rather than be stopped at sign off. The Finance Manager has also seen that software based SANs enable the IT Manager to repurpose existing hardware, or to elect to buy lower cost hardware, as opposed to always chasing newer, high cost hardware, to get the required functionality.

The inherent beauty of storage virtualisation software is that it can bring high performance and high functionality along with hardware independence at lower investment and with lower operational costs. This approach can also be highly complementary to an IT Department's preferred hardware, giving an extra lease of life, or adding that extra functionality normally only available on highend disk arrays. So storage virtualisation, like server virtualisation, implies the use of software to overcome inherent hardware limitations, without regard to the make or model of the underlying storage devices; those who limit use of this powerful technology to a given hardware configuration, are doing the industry a disservice, setting users up for avoidable obsolescence. The central point of the debate lies not in hardware versus software, but in the hardware choices offered to run the storage virtualisation code, this year, next year, and the year after that.

Pick an appliance and your fate is sealed. The moment that appliance runs out of steam, be it processing power, I/O bandwidth or expansion slots, determines its end of life. The rate of change in the computer industry suggests that could be as short lived as 6 months. What would you say to anyone who told you that your server virtualisation license can only run on your current server? And that you have to buy a new license to move it to a bigger or faster server? Worse yet, that you have to buy them together from the same supplier, who only offers two models! And it only supports their "special" disks. Pretty ridiculous, but that is exactly what storage virtualisation appliance vendors promote under the header of being 'factory integrated'.

Does it matter whether you use Fibre Channel or iSCSI for a software based SAN? Both provide solutions for different needs today. Fibre Channel is very fast and easily outperforms iSCSI at the moment. It was designed and optimised for a SAN, and many companies have taken the jump and invested in Fibre Channel switches, Host Bus Adapters and storage, but it is costly compared to IP SANs where iSCSI uses NICs and switches that are commodity items, available at commodity prices. Often an enterprise that has already invested in Fibre Channel or needs the performance of Fibre Channel for its high transaction and high workload applications also uses iSCSI for lower performance applications.

Using the existing skills in an organisation of IP Networks rather than the 'dark magic' of Fibre Channel, means that human resources are more readily available and their costs are invariably lower. But as technology moves forward and iSCSI speeds increase from 10Gbit to 100Gbit and eventually to 1Tbit, the cost differences will be minor, let alone looking at FCoE, and other network technologies of the future.

Once again, only a truly independent software virtualisation solution can work with all these technologies today and future proof the options for tomorrow. Those who have adopted a hardware appliance have done so at their own peril, playing the future-guess game and possibly limiting their business.

DataCore performance testing with Sun 'Thumper' server

Recently had the chance to configure a SUN x4500 "Thumper" server with SANmelody 3.0.2 for connection to an VMware Vsphere4 environment. I was able to put together some basic benchmark numbers for this very interesting configuration which highlights the flexibility that DataCore software brings in designing storage solution to fit specific budget and storage requirements.

Barren County Schools Deploys DataCore Storage Virtualization: DataCore, Xiotech and VMware Combine

See the complete Barren County Schools case study here: http://www.datacore.com/BarrenCounty

Barren County Schools in Kentucky, has deployed its SANmelody storage virtualization solution to serve as the cornerstone of its entire virtual infrastructure. DataCore SANmelody works in tandem with Xiotech and VMware vSphere 4 in this total enterprise virtualization deployment. Currently, the virtual storage powered by DataCore serves a user community of 5,500 users – comprising 4,800 students and 700 faculty members.

“The biggest benefit for us was realizing a virtualized data infrastructure,” stated Steve Gumm, IT director, Barren County Schools. “Because we adopted storage virtualization, we now have a front-end piece whereby we can deploy any hardware behind it that we want. We can bring in an additional SAN if we want – whatever vendor we choose – and still use the DataCore product. We can just fold those SANs into our infrastructure and it would be seamless to the end user. Beyond this – with DataCore we were able to repurpose old equipment.”

The IT infrastructure that supports Barren County Schools went from 30 physical servers to four (4) physical servers running 30 VMs. Two DataCore SANmelody SANs each now run on DELL 2850 servers that became available from being decommissioned during the drive to virtualize. The data pool SANmelody is responsible for managing and keeping highly available is currently 16 TBs.

The team chose VMware vSphere on the virtual server-side. “We chose VMware because it was the only solution we saw that offered clustering,” noted Gumm. To support the virtual machines (VMs), the IT team looked at various SAN solutions on the market to be deployed as a backbone for its virtual infrastructure, supporting the VMware server virtualization software. According to Gumm, “We had looked into a couple of different SAN solutions. We already had an EMC SAN. But we also looked at the DELL EqualLogic solution – and did not like some of the features that were brought to the table, particularly in terms of failover.”

“What was particularly relevant to Barren County Schools was exactly what makes DataCore storage virtualization a ‘pure’ virtualization solution – and that is portability,” explained Craig Stein, systems architect, The Mirazon Group. “What I mean by that is that with SANmelody, users can deploy it as a front-end to any back-end hardware SAN that they choose – thereby virtualizing the data storage.

It was this flexibility that was most appealing to the IT team at Barren County Schools. Of equal importance was the fact that with DataCore, the customer owns the software. It does not get thrown out with the next generation of the hardware it is tied to – like some solutions. On the contrary, users can swap out newer hardware whenever they want. When decision time came, it was clear to Barren County’s IT team that this flexibility/portability characteristic gave them a vital piece of the virtualization puzzle.

In the end, DataCore SANmelody was paired with Xiotech hardware because it did bring “so much to the table,” according to Gumm. Among the features he highlights as “hard to pass up” are the ability to thin-provision clients, the ability to migrate data seamlessly to users, and the ability to do upgrades to the school system’s SAN infrastructure (the data structure) without truly having to do a forklift upgrade.

Complete Virtualization Environment Based on DataCore, Xiotech and VMware vSphere 4
“For all intents and purposes, we are 100% virtual,” commented Gumm. Barren County Schools has two data centers – one primary and one secondary. VMware vSphere is currently running on two, new PowerEdge servers. The Xiotech storage arrays are in both data center locations – the primary one and the “offsite,” or secondary, data center. The two locations contain a similar, mirrored, environment which includes two DELL vSphere servers and a Xiotech array which are attached to the SANmelody SAN server. To get to this, Barren County Schools migrated everything it had on an existing EMC SAN to the DataCore and Xiotech based SAN in a live environment using SANmelody to do so. The IT team mapped LUNs from the old SAN to the new SAN and while in production migrated all of the data to the new location.

“This is not one of those products where we were sold more than we bought,” concluded Gumm. “With DataCore SANmelody, we bought more than we were sold. We are getting far more out of it than I thought we would, which is a wonderful thing.”

Did DataCore Software Invent Thin Provisioning SAN Software?

The original post on the subject on DrunkenData: http://www.drunkendata.com/?p=1162

More recently:
Check out DataCore Software, the company that invented thin provisioning. Yes, ‘invented’, the first company to ship the network-wide thin provisioning capability, ala a SNIA defined Sparse Volume, back in 2002, well before 3Par, the company credited with the term “thin provisioning”. DataCore and 3Par were several years ahead of and have several years more experience in, thin provisioning, than the competition.

DataCore also provides space reclamation for any host O.S. type and does what 3Par, Compellent, NetApp, HDS and all the other hardware centric storage providers DON’T do, DataCore allows the end user to choose who’s disk and what type of disk technology they want to use, freeing them from the shackles of the storage silo model of having to fill all those expansion trays and drive slots from the given company, where the first time buyer sweetheart deal is long gone.
Test Drive it now!
Try thin provisioning with your disks or storage array, a 30 day trial download is available at: http://www.datacore.com/products/prod_SANmel_trynow_form.asp

Plus, given the fact it’s openly running on industry standard commodity hardware, it’s always at least a generation ahead of all the ’specialized’ array controller heads, that are also running on commodity hardware in reality. Add to that the flexibility that type of solution provides when it comes to adding interfaces (iSCSI, FC), increasing interface density, speed (the first 8Gb FC target on the market), cache size, etc., you can’t find a better overall value.

Windows Server 2008 R2 Hyper-V cluster and DataCore: Live Migration Coming into Play in System Refreshes

http://blogs.eweek.com/storage_station/content/general/live_migration_coming_into_play_in_system_refreshes.html Storage virtualization provider DataCore Software is now deploying its SANmelody system in conjunction with the second release of Microsoft Windows Server 2008, working in clustered Hyper-V systems.

The news here is that a Windows Server 2008 R2 Hyper-V cluster now has the ability to "live-migrate" the virtual machines, meaning two cluster nodes have read/write access to the disk at the same time. This wasn't possible in the first release.

The time and money savings of this feature are potentially significant. Live migration elicited a lot of interest recently when DataCore showcased its storage virtualization software at Microsoft's TechEd Europe show in Berlin.

"What this DataCore-Hyper-V setup does is to minimize or even eliminate downtime, when we need to make system changes," said Jack Weisberg, IT director of an early adopter, the New York law firm of McNamee, Lochner, Titus & Williams. "So far this system is working very nicely. Plus, everything is redundant. We have redundant storage with DataCore. And we have redundancy built into the VM system."

When making the purchasing decision to replace some legacy hardware and software, Weisberg said it boiled down to DataCore's SANmelody versus an HP/LeftHand Networks system.
"In comparing both systems, we found both to be strong in terms of their capability of avoiding single points of failure," Weisberg said. "But I really like not being tied to specific hardware -- something DataCore enables. It was very important for us not to get locked into older platforms, when there is newer hardware available on the market that we could use with SANmelody."Using DataCore, the storage solution provider, P&J Computers, was able to use its preferred hardware of choice -- in this case, enterprise-class 6GB SAS drives. DataCore enabled administrators to add a couple of 10GB NICs (network interface cards) in these servers at a very low cost.

So, there's some real-world decision making at work. Is that something you're looking at for 2010?

DataCore Storage Virtualization Software Proves to Be a Great Fit for Microsoft Hyper-V and Cluster Deployments

Case in Point - Law Firm McNamee, Lochner, Titus & Williams
http://vmblog.com/archive/2009/11/16/datacore-storage-virtualization-software-proves-to-be-a-great-fit-for-microsoft-hyper-v-and-cluster-deployments.aspx

Microsoft Hyper-V and DataCore Software's Storage Virtualization Are Winning New Customers Together by Successfully Powering Virtual Infrastructures

DataCore Software announced its SANmelody storage virtualization solution has been deployed along with Microsoft® Windows Server® 2008 Hyper-V™ at the law firm McNamee, Lochner, Titus & Williams. "McNamee/Lochner" is one of the largest law firms in Albany, New York. "The combination of DataCore with Microsoft Windows Server 2008 for Hyper-V allowed us a lot of flexibility to deploy the best solution possible at McNamee/Lochner with the available hardware," stated Kelly M. Knowles, Network Engineer, P&J Computers, Inc.

Hardware Independence - Optimized by Virtualization
McNamee/Lochner had reached a point where the firm needed to increase its storage capacity. "Our storage was growing at a much faster rate than it had in the past," noted Jack Weisberg, IT director, McNamee, Lochner, Titus and Williams. "Moreover, the hardware that we were running on was out of warranty - so we were looking to get something new." Since 2004, the firm had been using a clustered SAN - an HP MSA 1000. Initially, a key requirement in a new system was something that had a solid approach to redundancy, as well as one that offered ease of expansion.Whereas LeftHand Networks was an early front-runner, since it seemed a logical replacement to the MSA SAN, P&J Computers presented DataCore SANmelody to the firm as well. "In comparing both systems, we found both to be strong in terms of their capability of avoiding single points of failure," noted Weisberg. "But I really like not being tied to specific hardware - something DataCore enables. It was very important for us not to get locked into older platforms, when there is newer hardware available on the market that we could use with DataCore SANmelody."

With DataCore, P&J was able to their preferred hardware of choice - in this case enterprise-class disks 6 GB SAS drives. Knowles praised the ability of DataCore to enable administrators to add a couple of 10 GB NICs in these servers for a very low cost as "tremendous."

P&J Computers - Trusted Solution Providers
DataCore partner P&J Computers, Inc., a data storage and IT service provider, sees the DataCore and Microsoft Hyper-V combination to be not only a good fit - but a great opportunity for both resellers and users alike. It also showcases P&J Computers' ability to be one of the first to implement the latest Windows Server 2008 R2 technology, which was released to the manufacturer (RTM) in July and was just released publicly in October 2009.

P&J Computers is engaged in several accounts where they are deploying DataCore storage virtualization, Windows Server 2008 and Hyper-V in joint configurations. What the partner saw in the new R2 release of Windows Server 2008 release was an opportunity for McNamee/Lochner to take some of the complexity out of its existing environment. What was imperative to making this possible was the release of Windows Server 2008 R2 and the live migration functionality - which was not in Hyper-V prior to R2.

A Virtual Infrastructure - Combining Servers and Storage to Support Mission-Critical Applications

DataCore SANmelody is now deployed in conjunction with a clustered Hyper-V system. Moreover, with a Windows Server 2008 R2 Hyper-V cluster McNamee/Lochner now has the ability to "live migrate" the virtual machines (VMs). Both cluster nodes have read/write access to the disk, at the same time. Running on this infrastructure, there are four (4) VMs that can "live migrate" between the two hosts. Currently, the second node at McNamee/Lochner is located onsite, albeit in a separate rack. "What this DataCore-Hyper-V set-up does is to minimize or even eliminate downtime, when we need to make system changes," noted Weisberg. "So far this system is working very nicely. Plus, everything is redundant. We have redundant storage with DataCore. And we have redundancy built into the VM system."

The multi-Terabyte data pool at McNamee/Lochner and the system is currently supporting 130 users. A third node - running Microsoft Data Protection Manager - is deployed for back-up. The applications McNamee/Lochner uses run on HP DL 380 G6s (dual processor, quad core with Nahalim). The 24 GB of memory can be expanded to 144 GB, if need be. "All the bread and butter applications for running McNamee/Lochner's business will run on this by year-end," noted Knowles.The next phase of the migration will entail moving what was clustered on Windows 2003 on the old SAN into the virtual environment as well. Space is allocated and P&J Computers just needs to schedule a date to do the cut-over.

Value Protection That Meets Business Objectives
In embracing a virtualized approach, McNamee/Lochner is looking three or four years down the road. Therefore DataCore's "Carry Forward Value Protection Program" - which translates to "Buy - Upgrade - And only pay the difference" - is for McNamee/Lochner a real insurance policy, whereby they might look at new hardware and still keep the same software. "I love this policy that DataCore offers," commented Weisberg. "I am entitled to upgrade the hardware I use with DataCore storage virtualization software. Rather than be forced to scrap my MSA 1000 SAN when it is at its end-of-life, with DataCore I can just buy new hardware and I can continue to use the software - on any new environment I choose. I really think this is awesome."

"We were looking for something redundant, reliable, flexible and expandable," summarized Weisberg. "The DataCore-Hyper-V combination really fit our needs. I certainly like the virtual environment. I also really like having redundant storage. And having seamless failover was key for us as well."

Download a simple pre-configured virtual SAN for Microsoft Hyper-V

http://searchservervirtualization.techtarget.com/news/article/0,289142,sid94_gci1374013,00.html#

DataCore released a version of its Virtual SAN Appliance (VSA) this week for Microsoft Hyper-V environments. The product allows customers to access Hyper-V features such as live migration, dynamic load balancing and high availability without having to purchase an external storage area network (SAN) storage.

Using locally attached internal disk drives, the DataCore VSA creates a virtual iSCSI SAN that can pool up to 1 TB of capacity. VSA includes the ability to "thin provision" VM storage to save capacity, create snapshots for instant volume cloning and speed up application performance by leveraging surplus server memory.

DataCore VSA comes as a virtual appliance in Microsoft-standard Virtual Hard Disk format, and can be downloaded from the DataCore website for a free 30-day trial.

Microsoft Tech-Ed Virtualization Pavilion Showcases DataCore’s Advanced Site Recovery Software; New Capabilites for Microsoft Hyper-V

Microsoft Virtualization Pavilion Showcases DataCore’s Advanced Site Recovery Software; Extends Disaster Recovery and Clustering Benefits of Microsoft Hyper-V
http://www.it-director.com/technology/storage/news_release.php?rel=14301

DataCore Software was featured last week within the Microsoft Tech-Ed Virtualization pavilion. DataCore showcased its ground-breaking Advanced Site Recovery (ASR) solution for virtual and physical IT infrastructures. Unlike other site recovery approaches that are limited to a specific vendor's virtual machine recovery, DataCore ASR enables both physical and virtual servers to be protected across multiple sites. The combination of DataCore ASR and Microsoft Hyper-V™/ Microsoft® Windows Server® 2008 R2 Failover and Clustering features enables businesses to embrace "real-world" Distributed Disaster Recovery (D-DR) – allowing organizations to cost-effectively spread disaster recovery (DR) responsibilities across several smaller sites.

Microsoft and DataCore Software Combine to Address ‘Real-World' Site Recovery

Taking machines from one site and replicating them to another site before a calamity unfolds is not new. But buyer beware. Many other disaster recovery products are limiting in that they assume recovery, from one environment to an identical or very similar environment or they support only a subset of the infrastructure. Often physical servers are not supported or require a separate solution from applications and virtual servers. DataCore ASR enables users to execute site recovery operations in a way that is fundamentally different from existing solutions in the marketplace today by bringing the data center together into a single solution.

"The industry is conditioned to think of DR as a one-to-one proposition. This places unreasonable demands on a single recovery site that mirrors the main site," argues Augie Gonzalez, product marketing director at DataCore Software."But most organizations aren't structured that way. They look more like a hub and spoke, with smaller branches emanating from the central data center. For this reason, DataCore's Advanced Site Recovery distributes the disaster recovery workloads among these smaller entities, allowing each of them to accept a more manageable role in keeping the business going."

DataCore Software Updates Storage Virtualization Free Trial Software; Performance Acceleration, Migration Tools + iSCSI, Fibre Channel, FCoE Support

DataCore Software Updates Storage Virtualization Free Trial Software; Performance Acceleration, Migration Tools + iSCSI, Fibre Channel, FCoE Support
http://vmblog.com/archive/2009/11/03/datacore-software-updates-storage-virtualization-free-trial-software-includes-performance-acceleration-migration-tools-and-support-for-iscsi-fibre-channel-and-fcoe.aspx
DataCore Software announced that it has updated its Free Trial software, which is architected to optimize and manage users’ storage. This free trial of SANmelody™ iSCSI, Fibre Channel over Ethernet (FCoE), and Fibre Channel SAN evaluation software, comes with performance acceleration, content migration, snapshot and thin provisioning – all included. The evaluation software enables data centers and IT departments to consolidate and maximize their disk capacity utilization. SANmelody simplifies management and leverages existing storage hardware and networking to efficiently serve the storage needs for Windows, Netware, MacOS, UNIX, and Linux systems as well as Microsoft, VMware and Citrix virtual servers and desktops.

The Free Trial software http://www.datacore.com/products/prod_SANmel_trynow_form.asp supports group snapshot and cloning, simple content migration and iSCSI and Fibre Channel as well as FCoE.

FCoE Connectivity - Access Fibre Channel storage pool via the LAN switching infrastructure. Application servers and other storage consumers can now access SANmelody nodes equipped with Fibre Channel SAN connections using their Ethernet Network Interface Cards (NICs). This capability takes advantage of the new Fibre Channel over Ethernet protocol and FCoE-compliant switches.

Group Snapshot and Clone Command - Synchronize online snapshots across inter-dependent volumes. This capability coordinates multiple snapshots to occur at the same time across a group of related volumes. It ensures point-time synchronization of file systems and application data that reside on different disks. Fast and efficient disk-to-disk backups across volumes are greatly simplified – plus it ensures that clones created on new equipment are an exact replica of their predecessor.

Content Migration - Relocate active drives into the virtual storage pool. This feature enables existing drives formatted with NTFS file systems to be incorporated easily into the SANmelody storage pool. These physical drives are first un-mounted from the application servers where they were once active, and then reconnected behind a SANmelody node. The SANmelody node acts as an intermediary between the application server and these drives. To take full advantage of SANmelody advanced virtualization features, their contents may be copied to virtual disks using snapshots. The relocated drives can then be wiped clean and included in the physical storage pool as additional capacity, or they may be decommissioned.

Storage Technology News - DataCore SAN management software adds capabilities to storage arrays

http://searchstorage.techtarget.com/news/article/0,289142,sid5_gci1373639,00.html

The Barren County, Ky., school district discovered it could make good use of management features such as thin provisioning and remote mirroring even if they're not included natively with its storage arrays. As part of a virtualization project, the district installed an Emprise 5000 storage system from Xiotech Corp. and DataCore Software Corp.'s SANmelody software to increase uptime and decrease the impact of maintenance on its users.

Barren County school district includes around 4,600 students and 700 faculty. IT Director Steve Gumm and his team handle a high school, middle school, seven elementary schools, the board office, a day care location and four other buildings...

Gumm revamped his storage setup over the summer after the district virtualized all 30 of its servers with VMware. Gumm thought it would be a good time to modernize his storage network, which consisted of a four-year-old EMC iSCSI SAN. The district first went to its server vendor Dell and took a look at an EqualLogic iSCSI SAN. But Gumm wasn't comfortable with the idea of failing over between EqualLogic controllers in different sites during frequent network upgrades.

...Barren installed two 16 TB Fibre Channel systems in separate buildings and Gumm uses SANmelody to manage them with the uptime he wants.

"With SANmelody, we can thin provision those SANs," he said. "We're not utilizing all the space, and thin provisioning lets us use just what is needed at the time. We also use it for data mirroring between both locations. If we need to do maintenance or I need to re-boot my SAN for whatever reason, we drop the SAN here, failover, do our maintenance, failback, and we're up and going."...

"We can manage whatever maintenance needs to be done, whenever we need it," Gumm says of his new setup. "The biggest benefit coming down the road is we're not going to have to do forklift upgrades. When it comes time to add storage, we won't have to rip out the unit. We can add to the unit and allow DataCore to manage where we move data to."

Computer Technology Review: Homecare Homebase deploys DataCore storage virtualization solutions

Homecare Homebase [HCHB] deploys DataCore storage virtualization solutions
...HCHB empowers the homecare and hospice industry to be more effective in providing healthcare to patients. Currently 4,375 office workers and over 11,000 field agents rely on applications running on HCHB’s IT systems infrastructure. Everything HCHB customers do is mobile and all of the applications HCHB offers these agents in the homecare industry are both mobile and real-time.

“The combination of the VMware platform along with the DataCore SAN has really given us a lot of flexibility to more rapidly deploy consistent images of systems – especially in the Citrix farm,” explained Chris Kane, director of technical operations, Homecare Homebase. “In addition, the VMware-DataCore combination has given us much improved VMotion capability – where the SAN enables us to do maintenance on the host in the middle of the day, if we have to.”

...“We quickly outgrew the storage we had – both in terms of the amount of space presented by those units as well as the performance of those units,” noted Kane.HCHB has a big Microsoft SQL Server shop and tended to back-up its customer information using these snap units at each site to replicate for disaster recovery purposes. According to Kane, the units were just not able to keep up with the back-up planning and also the synchronization of the data. “The storage we had before DataCore became troublesome,” commented Kane. “We were in desperate need, not only of space, but also of reliable storage.”

...On its own, HCHB looked at EqualLogic from Dell, LeftHand from HP, as well as EMC and NetApp.Noted Kane, “The DataCore SAN solution suits our IT administrative style better than the other solutions we saw. The more we looked at traditional SAN solutions – encompassing hardware, software and professional services – for us, these weren’t the type of solutions that we have typically dealt with. We have a lot of skilled technology people in house and we like to be able to get our hands on every piece of technology we bring in. The fact that DataCore is Windows-based gives us a little more control – particularly being able to manage the hardware ourselves. Moreover, DataCore gave us a full, high availability solution. Not to mention that DataCore is very competitive price-wise – so all of this made DataCore the best choice for us.”

...Virtualizing the Citrix environment with VMware and DataCore running in tandem has provided a real, tangible benefit in terms of system maintenance and administration. Before – with the physical, Citrix environment, the IT team at HCHB was very limited in terms of what they could do with those systems during the working day.“Just the patch management aspect of keeping up with all the physical boxes has been greatly improved in the virtual environment because we can deploy patch templates versus having to constantly update from Microsoft or other vendors,” added Kane.With the SAN in place, the virtual environment at HCHB has delivered real benefits to customers and system administrators alike. These benefits are a direct result of the improvements made possible through these new virtualization capabilities. For instance, HCHB as a whole is able to roll out new services more rapidly and consistently. The current databases and applications that HCHB uses internally to run its business, such as file servers (documentation that support internal needs) or Microsoft Office Sharepoint (that supports customers), have benefited, either directly or indirectly, from the VMware virtual infrastructure and the DataCore storage virtualization SAN.

...“It has been very rapid growth for us recently,” summarized Kane. “And I am very, very happy with the performance we are getting both out of VMware and the DataCore SAN at this point. The SAN has made a world of difference to us. There were many choices for a SAN – from a variety of SAN vendors. For us, DataCore was the right fit. DataCore gives us the ability to select and maintain the hardware of our own choice. It gives us the ability to have a fully redundant, highly available SAN – not just at the controller-level, but at the storage-level itself. That, combined with the price point DataCore’s portable SAN software offers – even when having to purchase hardware and licensing – is still much more effective than anything else we found on the market.”

New SANmelody Feature highlighted: Non-disruptive disk, array, or vendor substitution - Raw Disk Mirroring

Non-disruptive disk, array, or vendor substitution - Raw Disk Mirroring
http://sanmelody.blogspot.com/2009/10/raw-disk-mirroring-non-disruptive-disk.html With the release of SANmelody 3.0 PSP2 comes the addition of "raw disk mirroring" which I have touched on in the previous post.
I really don't think this new capability has been given enough coverage when you look at the flexibility it provides. The ability to replace "backend" raw disks without interfering with Virtual Volumes, NMV Volumes or the NMV Pool itself, all while I/O operations continue as normal is an incredible capability.Let look at a scenario: Client maintains a large VMware environment serving ~10TB of data across ~40 thin provisioned virtual volumes server from a SANmelody HA environment with "Vendor A" storage at the backend consisting of many 2Gb FC 146GB 7.5K drives... They are replicating this data to a DR site consisting of SANmelody with "vendor C" disk.Customer has decided to de-comission "vendor A" storage, in place of "vendor B" which contains new 4Gb 300GB 15K rpm drives.Solution: Utilising raw disk mirroring we are able to serve up new capacity from "vendor B" and mirror the raw disks with "vendor A" without touching any of our provisioned volumes. Once mirrors are established we can disconnect "vendor A" and continue as normal without any interuption to the business or to our DR replication solution. But I don't run SANmelody or SANsymphony?.. The 2nd piece of this puzzle is "Proxy volumes support". If you have existing vendor storage and would like the type of flexibility discussed above to migrate data, it can be done. DataCore can "pass through" all of your existing served volumes (with file systems) and mirror the data while it is serving I/O..........
