failover

Automatic and nondisruptive transition of functions from an active FRU that has failed to a

backup FRU.

FC-0

The Fibre Channel layer that describes the physical link between two ports, including the

transmission media, transmitter and receiver circuitry, and interfaces. This consists of a pair of

either optical fiber or electrical cables (link media) along with transceiver circuitry which work

together to convert a stream of bits at one end of the link to a stream of bits at the other end.

FC-1

Middle layer of the Fibre Channel physical and signaling interface (FC-PH) standard, defining

the 8B/10B encoding/decoding and transmission protocol.

FC-2

The Fibre Channel layer that specifies the signaling protocol, rules, and mechanisms required to

transfer data blocks. The FC-2 layer is very complex and provides different classes of service,

packetization, sequencing, error detection, segmentation, and reassembly of transmitted data.

FC-3

The Fibre Channel layer that provides a set of services common across multiple node ports

(N_Ports) of a Fibre Channel node. The services are not commonly used and are essentially

reserved for Fibre Channel architecture expansion.

FC-4

The Fibre Channel layer that provides mapping of Fibre Channel capabilities to upper level

protocols (ULP), including Internet protocol (IP) and small computer system interface (SCSI).

FC-AL

Acronym for Fibre Channel arbitrated loop. Synonymous with
