HDS Thin Provisioning Seen as Large Enterprise Boost

HDS has extended existing thin provisioning on its Universal Storage Platform V (USP V) series to encompass attached external arrays from other vendors.

Just who will really use this, and why?

At least one analyst says there's a solid market out there. "There are many candidates. They're definitely larger organizations, with 500 Gbytes or more, or even 1 Pbyte or more of storage," says David Vellante, co-founder and senior storage analyst for analyst forum Wikibon. "Companies that, through mergers or acquisitions, suffer from 'SAN creep,' where you've got storage applications from different vendors fenced off in different tiers... could see 30 percent to 40 percent improvement in storage utilization."

Previously, HDS customers could virtualize a pool of storage encompassing not only HDS's internal Fibre Channel arrays but those of other vendors as well. Replication, snapshots, and migration functions of the USP V could be applied to the pool.

What HDS is offering now is a software key-activated upgrade to the USP V and smaller, rackmount USP VM that adds thin provisioning to the mix. OEMs HP and Sun will resell the feature on their USP V-based systems, HDS says.
