HDS Shrinks USP V

Hitachi Data Systems (HDS) has renewed its campaign for heterogeneous storage virtualization via a new, smaller version of its latest Universal Storage Platform (USP) V series. (See HDS Unveils New USP V Series.)

HDS's intriguingly named USP VM is a shrunken-down version of the USP V the company announced in May 2007. It offers 72 Tbytes of internal Fibre Channel storage, compared with 332 Tbytes for the regular high-end version; and it supports up to 96 Pbytes of external storage across multivendor Fibre Channel (4 Gbit/s is supported), iSCSI, NAS or mainframe network environments, the vendor claims, compared with 247 Pbytes for the older model. The USP VM works with other USP series products and will connect with HDS's midrange AMS1000 as well.

The USP VM consumes 220 volts of power and still performs at 1.2 million IOPS (input/output operations per second), HDS says.

The vendor boasts that it's fully equipped the new USP VM with thin provisioning, heterogeneous virtualization, tiered storage, and the ability to handle file and block-level data. When it's generally available it will support VMware ESX Server 3.0 to incorporate virtual servers in a managed pool of storage; and it comes with HDS's Universal Volume Manager and Volume Partition Manager, which carve specific increments of internal or external storage in support of specific groups or applications.

The USP VM can run with Fibre Channel disk attached or as a standalone controller-only virtualizer. In the latter configuration it embodies HDS's preferred approach to storage virtualization -- namely, in the controller. According to HDS, the approach scales better and is more secure than other techniques.
