Over the past year or so, we've seen an increase in interest in Internet Protocol (IP) storage in the Ask the Expert section
Another factor that is driving interest in IP storage is the emergence of products that support FC and iSCSI in one system. It seems as if the discussion is shifting from FC vs. iSCSI to FC and iSCSI virtualized in such a way that users don't have to think about which protocol they need to use on a day-to-day basis. Network Appliance Inc. (NetApp) offers products that handle block (FC and iSCSI) and file (NAS) access to data stored in FC SAN storage arrays; BlueArc Corp., Pillar Data Systems, 3PAR Data Inc., and many others have designed products from scratch to handle both protocols. Bigger players, such as Hewlett-Packard Co. (HP) and EMC Corp. have recently redesigned products to do the same.
"More and more you will see vendors shift their discussion and focus away from the wire or interface to that of the functionality of the storage system and how the storage system addresses different management capabilities," Schulz said. "We are seeing more vendors provide flexibility in connectivity to enable customers to access their storage with the most applicable interface at a given point in time. This approach enables customers to focus more on the storage system's overall capabilities to address storage management using the appropriate storage interface for their given needs at that particular point in time."
