peripherals. Fibre Channel is capable of transmitting at rates exceeding one

gigabit per second in both directions simultaneously.

Fibre Channel -

Arbitrated Loop (FC-

AL)

One of three existing Fibre Channel topologies, in which 2 to 126 devices are

interconnected serially in a single loop circuit. The arbitrated loop topology

supports all classes of service and guarantees in order delivery of frames when

the source and destination are on the same loop.

Fibre Channel

Protocol for SCSI

(FCP)

FCP defines a Fibre Channel mapping layer (FC-4) that uses FC-PH services to

transmit SCSI command, data, and status information between a SCSI initiator

and a SCSI target. Using FCP enables transmission and receipt of SCSI

commands, data and status, across the Fibre Channel using the standard Fibre

Channel frame and sequence formats.

frame The smallest, indivisible unit of information transfer used by Fibre Channel.

Frames are used for transferring data associated with a sequence. Frame size

depends on the hardware implementation and is independent of the ULP or the

application software.

GBIC An acronym for the Gigabit Interface Converter.

Gigabit One billion bits or one thousand megabits.

GigaBit Interface

Converter

A physical component that manages the functions of the FC-0 layer, which is

the physical characteristic of the media and interface, including drivers,

transceivers, connectors, and cables. Mounts on a FC adapter card and

connects the 4x50 to a FC host. Also referred to as a Physical Link Module

(PLM).

GLM An acronym for the Gigabaud Link Module.
