What is NAS/SAN fusion?
NAS/SAN fusion is the ability to connect NAS “heads” to a SAN in order to provide file services to clients. Application servers can also hook into the SAN to provide block services “naturally.” This architecture combines the best of both technologies. NAS now scales to the limits of the SAN, and portions of the SAN storage now become accessible to the company’s broader TCP/IP based network. No more storage islands. This all drives down costs by having one centrally managed storage pool that provides application servers and end users access to storage.
