I wonder why you always mention IBM, EMC, SUN, HP, Compaq and HDS as SAN vendors and ignore Network Appliances. The reason I asked it is that I have some examples of configuration that I consider a SAN. Suppose we have several NetApps connected at the back end through Fibre Channel. We connect every NAS box to the Fibre Channel switch or router (iSCSI/FC) connected to a tape library. Using NDMP we have all data stream flow directly to the tape library. Can we call this structure SAN or not?
No problem. The reason I don't usually mention NetApps when I talk about SAN is because they are a NAS vendor. There is a NAS expert on the SearchStorage site that answers those questions.
