virtual hub

A set of switch ports on the same fabric that are placed into a logical grouping and use an address spoofing mechanism to emulate a Fibre Channel Arbitrated Loop (FC-AL) hub. A virtual hub can be comprised of all the ports on a single switch or several ports on one or more switches. It is used primarily to allow older loop-only devices to be attached to a switched fabric and be accessible as though they were fabric capable.
