BANGALORE, INDIA: 'VMware VSA is for entry-level virtualization customers who don't have any kind of shared storage today. The HP VSA has full SAN feature set, scale out architecture, interoperability with the HP P4000 LeftHand SAN," writes Calvin Zito, HP StorageWorks social media manager, in his blog post on 'Around the Storage Block Blog'.

This was in response to various reports that claimed that with vSphere Storage Appliance, VMware will be competing with HP. He gives his take on the two VSAs - VMware vSphere Storage Appliance (VSA), launched on Wednesday, and HP P4000 LeftHand Virtual SAN Appliance (VSA), which is already there in the market for quite sometime now, to be precise 'it's been shipping for over four years'.

Calvin says, 'There really isn't much overlap between where each VSA fits'. Here are a few points as given on the blog:

HP VSA is iSCSI based; VMware is NFS.

HP VSA can be added to an existing P4000 SAN; VMware VSA is standalone.

HP VSA is scalable up to 10 nodes; VMware VSA is either 2 or 3 nodes.

However, one wonders, how the @HPStorageGuy missed out VMware's official release, where the latter had said that with its VSA it will extend vSphere's capabilities to SMBs so that they can do away with 'the cost and complexity of shared storage infrastructure'.
