Hitachi Steps It Up in Midrange NAS: Page 2 of 3

Continued growth in that sector is what Hitachi's banking on here, Vellante notes. "And they've found a place where traditional NAS players like NetApp haven't been strong. BlueArc got to market first with technology that by all accounts is pretty stable."

Storage professionals may wonder, why not just get them direct from BlueArc? Its Titan 1100, on which the HDS platforms are based, is less than half the price, starting at $75,000.

HDS is quick to point out that its new platforms are integrated with the Hitachi HiCommand Software suite for storage and device management. That also enables customers to blend file- and block-based virtualization. Hitachi has also added synchronous and heterogenous replication to the mix.

Combining file and block virtualization is a neat trick but may be slightly ahead of its time. "The whole idea of treating block and file [storage virtualization] as one has been around on vendor whiteboards for a while now. But people are beginning to see the possibility of bringing them together," Vellante says. "They remain separate, despite announcements like this. We're years away from true integration."

HDS said the new platforms will support 64-bit SCSI addressing changes that allow for LUN support up to 64 Tbytes. The new clusters will also scale up to eight nodes, providing 2 Pbytes of capacity per node or per cluster, the vendor claims.
