There's still work to do, such as bug cleanups, to get the Common Information Modelan evolving universal language for storage productsready for prime time.Kevin Gungiah, director of systems administration at Landmark Communications Inc.s The Weather Channel, in Atlanta, manages 22 terabytes of data on a Hitachi Ltd. Lightning 9960 SAN with Brocade Communications Systems Inc. switches. Gungiah said its easier to manage than most storage systems, thanks to standards-based, third-party software. "We evaluated a lot of different vendors. Hitachis and Brocades software have several limitations in terms of functionality. The functionality I got from [startup AppIQ Inc.] was what I was looking for. I like the fact that its CIM-based," Gungiah said, referring to the evolving Common Information Model.
With a code freeze earlier this month, CIMreferred to in combination with its implementation standard as Storage Management Initiative Specification 1.0, or SMI-S, by the Storage Networking Industry Associationis in its final stages before vendors can start certifying storage area network and switch products with it this fall.
