HP's purchase this week of PolyServe is the latest, but by no means the only, indicator that storage virtualization is poised to play as big a role in enterprise development as server virtualization. Basically, what PolyServe brings to the HP StorageWorks line is the ability to control any number of blade systems working with the various flavors of SQL, SAP and Oracle, and then tie it all together with a unified storage platform.
The move is likely to greatly boost the ability of the c-Class blade system which, if you recall, has already been outfitted with "Virtual Connect" technology to provide a ready-made virtualization platform that allows you to swap individual blades in and out of a chassis with ease.
HP is not the only major vendor to see the storage virtualization light. Sun Microsystems recently agreed to resell the Hitachi Universal Storage Platform and Network Storage Controller. The solution is likely to be the storage of choice for LSI/Engenio environments that Sun also OEMs.
Network architects, meanwhile, are still buzzing over the fact that VMware has adopted iSCSI across its product lines, making the implementation of virtual storage networks cheaper and easier than ever.
As the server side of the house has already realized, it won't be long before virtual storage becomes the norm, rather than the exception.
