A specification introduced by a group of 16 storage companies in 2002 in an effort to improve the interoperability of storage management systems. The Bluefin specification, which the vendor group has submitted to the Storage Networking Industry Association, uses the Common Information Model (CIM) and Web-Based Enterprise Management (WBEM) to discover and manage resources in a multivendor storage-area network (SAN) through common interfaces. See CIM, WBEM and SAN.
