HDS's Yoshida Mounts MAID Assault

CTO responds to Byte and Switch with aggressive power saving claims

Hu Yoshida, CTO of HDS, insists that his company has no MAID offerings, despite unveiling its own power saving technology earlier this week.

The exec even chased down reporters who highlighted the resemblance between HDS's offering and MAID, a technology for spinning down disks. "With MAID, everything is idle -- you spin it up when you need to access [the drives]," he says. "Our approach is the opposite -- everything is spinning, and you power it down when you don't need it."

A number of vendors, including Copan, Nexsan, Fujitsu, and NEC, have championed MAID technology as a way for users to reduce their power costs. Copan, for example, says it now has over 100 customers for its technology and is planning to bulk up its database archiving and records management strategies next year.

With users becoming increasingly concerned about data center energy costs, HDS is targeting the somewhat long-winded Power Savings Storage Service (PSSS) at its midrange RAID arrays. "We need to find a nice acronym for it," admits Yoshida, explaining that the offering will be available as part of HDS's Adaptable Modular Storage (AMS) and Workgroup Modular Storage (WMS) systems next month.

"We spin [the disks] down based on RAID array group," says Yoshida, adding that, because the disks are spinning all of the time, PSSS will avoid the storage "performance hit" associated with MAID, where disks are idle for long periods.
