Flexibly provisioning and accessing storage resources using virtual worldwide names

摘要

A method, apparatus, system and computer program product that provide a virtual worldwide name (vWWN) nameservice in a Fiber Channel storage area network (SAN) are provided. Embodiments of the vWWN nameservice can receive a request for a vWWN from a node in the SAN, where the request includes a identifier associated with resources in the SAN, then determine if the identifier matches contents of a field in one or more entries in a vWWN table or database, and provide the vWWN associated with a matching entry to the requesting node.
