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.
