@30659 The other idea is a virtual storage area network (SAN) where it is possible to create multiple subnetworks or subfabrics that are physically interconnected, but logically isolated. This is similar to a network virtual LAN where the LANs are physically connected, but virtually isolated to keep local traffic local and keep network or management traffic from propagating out over the network unnecessarily. In practice, a virtual SAN can also combine separate physical fabrics (SAN islands) into a single logical SAN, which can often improve SAN resource utilization.
