FAN 1) Fabric Address Notification. Keeps the AL_PA and fabric address when loop re-initializes if the switch supports FAN. 2) File Area Network. The set of systems and software that enable centralized management of file data to improve user and administrative efficiency. Fan-in The ratio of hosts to storage devices. It is the view of the SAN from the storage port's perspective. Fan-out The ratio of storage devices to hosts. It is the view of the SAN from the host port's perspective. FastWrite A Fabric OS feature running on top of FCIP that accelerates Write operations from a host to a target device; eliminates the latency associated with long distance in FCIP. F_BSY Fabric Port Busy Frame. A frame issued by the fabric to indicate that a frame cannot be delivered because the fabric or destination N_Port is busy. FCA Fibre Channel Association. FC-0 Lowest layer on Fibre Channel transport; represents the physical media. FC-1 This layer contains the 8b/10b encoding scheme. FC-2 This layer handles framing and protocol, frame format, sequence/exchange management, and ordered set usage. FC-3 This layer contains common services used by multiple N_Ports in a node. FC-4 This layer handles standards and profiles for mapping upper-level protocols such as SCSI and IP onto the Fibre Channel Protocol. FC-AL Fibre Channel Arbitrated Loop. FC-AV Fibre Channel Audio Visual. FC-CT Fibre Channel Common Transport. FC-FC Routing Service A service that extends hierarchical networking capabilities to Fibre Channel fabrics. It enables devices located on separate fabrics to communicate without merging the fabrics. It also enables the creation of LSANs. FC-FG Fibre Channel Generic requirements. FC-FLA Fibre Channel Fabric Loop Attachment. FC-FS Fibre Channel Framing and Signaling. FC-GS Fibre Channel Generic Services. FC-GS-2 Second-generation Fibre Channel Generic Services. FC-GS-3 Third-generation Fibre Channel Generic Services. FCIP Fibre Channel over IP protocol. FCoE Fibre Channel over 10 Gbit/sec Ethernet networks. Brocade SAN Glossary 1/29/2008 Page 9 of 29
