F
fabric A network of one or more Fibre Channel switches that transmit data between any two N_Ports
on any of the switches.
failover An automatic method for transferring operations from a failed system to a secondary, identical
system.
Fat tree topology A SAN topology where at least 50% of edge ports are dedicated as ISLs.
FC Fibre Channel. A comprehensive set of standards for concurrent communication among servers,
storage systems, and peripheral devices.
FC-AL Fibre Channel Arbitrated Loop. A serial, full-duplex, data transfer architecture for high-performance
storage systems.
FC-SONET Fibre Channel Synchronous Optical Network. A gateway that resides at the end of an inter-site
link and encapsulates Fibre Channel frames into SONET packets before transmitting the frames
over the network.
FC-SP Fibre Channel Security Protocol. A security protocol that protects in-transit data.
FC-to-ATM Fibre Channel to Asynchronous Transfer Mode.
FC-to-IP Fibre Channel to Internet Protocol.
FCC Fibre Channel Congestion Control. A feature that allows C-series switches to intelligently regulate
traffic across ISLs and ensure that each initiator-target pair of devices has the required bandwidth
for data transfer.
FCDM Fibre Channel Disk Module.
FCF Fibre Channel forwarder.
FCFW Fibre Channel FastWrite.
FCID Fibre Channel ID.
FCIP Fibre Channel over Internet Protocol.
FCoE Fibre Channel over Ethernet Protocol.
FCS 1. Fibre Channel switch. 2. Fabric Configuration Server, a data access policy that determines
which switches can change fabric configurations.
FCSA Fibre Channel ServerNet Adapter. The HP NonStop version of Fibre Channel HBAs, used to
connect to XP disk arrays.
FDISC Fabric discovery.
FE FE front-side path. A path between the host (host bus adapter) and the DPM.
Front-end host visible (SVSP).
FEC Forward Error Correction.
FF Full-featured.
Fibre Channel A serial data transport infrastructure and protocol used to implement SANs. See also http://
www.fibrechannel.org/ and http://www.t11.org/.
FIP FCoE Initialization Protocol.
FLOGI Fabric login.
FOS Fabric Operating System.
FPMA Fabric Provided MAC Addressing.
