"VMware customers are demanding that the many storage-related interruptions they face while making metro-wide, virtual machine migration, failover and load balancing be eliminated. Solutions like those offered by DataCore are addressing these interruptions and are critical to making these tasks practical," said George Crump, senior analyst at Storage Switzerland.Visitors to VMworld Europe 2009 will be among the first to learn how new versions of DataCore SANmelody(tm) and SANsymphony(tm) storage virtualization solutions materialize into SAN-wide performance boosts, radically simple, high-availability, and optimum disk utilization for VMware Virtual Infrastructure customers. DataCore's new lineup of VMware Ready Certified(tm) solutions will be showcased at Europe's largest virtualization community in Cannes, France.
DataCore SANmelody and SANsymphony Support 64-bit "Mega Caches" Boost SAN-wide Performance
Leading the list of new features in SANmelody 3.0 and SANsymphony 7.0 are native 64-bit controller software with support for mega cache capacities. "In large scale, consolidated data storage, cache is king," commented James Price, vice president channel and product marketing, DataCore Software. "DataCore's solutions will now support up to a terabyte (TB) of cache. They dwarf anything in the market and scale linearly with each node that you add to the fabric." The entire working set of a large number of virtual machines can now be kept in SAN-wide cache for unprecedented performance. Behind the cache, VMware customers can grow their storage pools from a few hundred gigabytes to multiple petabytes.
Radically Simple, High-Availability for Non-Stop Storage Virtual Infrastructure Needless to say, storage pools of such immensity are in constant flux. With this in mind, the new product enhancements are fully integrated into DataCore's radically simple, high availability solutions for VMware. Only DataCore allows maintenance, upgrades, expansion, and failures to take place throughout portions of the storage infrastructure without disrupting applications. "VMware customers are demanding that the many storage-related interruptions they face while making metro-wide, virtual machine migration, failover and load balancing be eliminated. Solutions like those offered by DataCore are addressing these interruptions and are critical to making these tasks practical," said George Crump, senior analyst at Storage Switzerland.
Full Use: Efficient Space Reclamation for Thinly Provisioned Storage Both SANmelody and SANsymphony offer the choice to thinly provision virtual disks rather than tie up physical capacity when LUNs are first created. This is particularly desirable with virtual machines that generally consume only a small fraction of the total volume assigned to them. In the new releases, previously allocated or thinly provisioned space will be automatically reclaimed in the background after applications or file systems no longer need it. With this functionality, the SAN returns unused capacity that may have been temporarily needed for some operations and can now further optimize resource utilization.
Windows Server 2008-based, Universal Storage Controllers
Configuring DataCore software on x86/X64 Windows servers transforms them into universal storage controllers. ESX servers and virtual machines (VMs) needing storage, connect to the DataCore controllers using iSCSI or Fibre Channel. All of the popular operating systems, including Windows Server 2003, 2008, Unix, Linux, NetWare and MacOs can take advantage of DataCore's SAN-wide storage virtualization features. In small configurations, the DataCore controller is hosted on a VM as a virtual appliance alongside application VMs. The SAN is completely virtual needing no external storage. Larger configurations dedicate physical servers to this storage virtualization role and typically include both internal disk drives and external arrays. The new SANmelody 3.0 and SANsymphony 7.0 releases have been re-architected to exploit the power and scalability of Microsoft Windows Server 2008 for either virtual or physical x86 and x64 platforms as universal storage controllers.
New Hypervisor Migration Support and Tighter Integration to VMware Virtual Center. DataCore's "Transporter" time saving migration facility is a new option in SANmelody 3.0 and SANsymphony 7.0. Transporter migrates disk images and workloads between different operating systems, hypervisors and storage subsystems - eliminating lengthy backups and restores due to complicated format conversions. In addition, a plug-in for VMware's Virtual Infrastructure Client is a no-charge option that allows administrators to non-disruptively provision, share, clone, replicate and expand virtual disks among physical servers and VMs.
