NAS gateways allow IP access to SANs

摘要

Network-attached storage quickly has been adopted in corporations because IT managers were drawn to NAS appliances' low cost and quick and easy deployment. But the flexibility comes at a price - the more islands of storage that surface, the more they complicate the task of storage management. As a result, many companies have rolled out storage-area networks to consolidate their storage environments. A NAS gateway bridges the NAS and SAN worlds by connecting IP networks to Fibre-Channel-based storage. These highly optimized file servers help corporations preserve their storage investments.
