Among some of the more interesting news is Compaq's introduction of two network storage products and Brocade's launch of a 16-port switch. Not one to sit still for long in the storage market, Compaq has unveiled Universal Storage and the Enterprise Virtual Array (EVA), the first product to incorporate the vendor's VersaStore technology. EVA allows users to aggregate storage into multiple, virtual pools that can be expanded in real-time. EVA allows customers to define the data protection requirements for each of the virtual pools on a pool-by-pool basis. Traditionally, once the data protection, or Redundant Array of Inexpensive Disks (RAID) level is set for a disk subsystem, that protection must be used throughout. The V-RAID (Virtual RAID) capability in the EVA allows the protection level to be specified for each pool. Included in the EVA is the ability to produce snapshot copies of your data. EVA supports the traditional "Snap" capability whereby storage space is pre-allocated to create the copy. The technology also supports V-Snap, which uses space as updates are made to the data. Finally, EVA supports what Compaq calls "Snapclones." Snapclones are similar to traditional snapshots however, instead of having to wait for all the data to be copied, applications can access the Snapclone immediately after the Snapclone call. This makes performing backups of changing data significantly easier and faster. Compaq's other announcement, Universal Storage, is not a new concept as EMC is offering the functionality too. Very simply, Universal Storage allows customers to manage all their storage in a storage-area network (SAN), whether the data is being accessed directly by an application via block-level transfers through a server, or by a network-attached storage appliance connected to both the local network and the SAN. As with the EVA, Universal Storage gives customers flexibility in managing their current storage resources as well as scalability when more storage resources are required. Finally on the storage-networking front, Brocade announced a 16-port switch, the Silkworm 3800. The 3800 brings together Brocade's third generation ASIC technology that supports 2G bit/sec speeds, as well as new Advanced Fabric Services. The fabric services include hardware enforced zoning for greater security; inter-switch trunking for greater performance and reliability; plus improved performance and health monitoring. The latest version of Brocade's API is available for storage management software vendors. There are many, many more announcements that came across my desk this week and I could write about them for days. However, I found these especially interesting. _______________________________________________________________ To contact Anne Skamarock: Anne Skamarock is an analyst with Enterprise Management Associates (http://www.enterprisemanagement.com).
