Access "Midrange Arrays Inherit High-End Smarts"

Published: 16 Oct 2012

Virtualization layers, once a feature of only the most expensive storage subsystems, are beginning to ship with midrange storage systems. For example, Hewlett-Packard recently introduced an entry-level version of its StorageWorks Enterprise Virtual Array (EVA). The EVA 2C2D starts with two controllers and two drive shelves, and as few as eight disk drives. Before the 2C2D, the smallest EVA was the 2C6D, with six drive shelves. The thinking behind the EVA 2C2D is to give customers a cost-effective entry point into the EVA line, says Pete Korce, HP's director of enterprise storage arrays. "The message we were getting from our customers was that they wanted to start small," he says. Still, the 2C2D's two controllers can support up to 240 drives, which, assuming 72GB drives, translates to more than 17TBs. And in the next couple of months, HP will add even less expensive models to its EVA line, Korce says. The low-end EVAs will have dual controllers, "but there are other features we can take out to reduce the cost." The benefits of array-level virtualization ... Access >>>
