See Fibre Channel - Arbitrated Loop.

FC adapter

A printed circuit assembly that translates data between the FC host processor’s internal bus and

 

the FC link. This is also known as an HBA, or Host Bus Adapter.

FC device

A device that uses Fibre Channel communications.

FC port

An opening at the back of the interface card that provides a fiber optic connection between

 

the FC adapter and the FC host.

FC-SCSI hardware

A FC term describing a list of values showing the physical hardware path of the FC host to the

path ID

target device.

 

Format: Bus_Converter/Adapter_Address.Protocol_Type.Area.Port.Bus.Target.LUN

 

Example: 8/4.8.0.0.2.4.0

fiber

A fiber optic cable made from thin strands of glass through which data in the form of light

 

pulses is transmitted (LASER, LED). It is often used for high-speed transmission over medium

 

(200m) to long (10km) distances but it can be used for short distances (<200m).

fibre

A generic FC term used to cover all transmission media types specified in the Fibre Channel

 

Physical Layer standard (FC-PH), such as optical fiber, copper twisted pair, and copper coaxial

 

cable.

fibre channel (FC)

Logically, the Fibre Channel is a bidirectional, full-duplex, point-to-point, serial data channel

 

structured for high performance data communication. Physically, the Fibre Channel is an

 

interconnection of multiple communication ports, called N_Ports, interconnected by a switching

 

network, called a fabric, a point-to-point link, or an arbitrated loop. Fibre Channel is a

 

generalized transport mechanism that has no protocol of its own or native input/output

 

command set, but can transport any existing Upper Level Protocols (ULPs) such as SCSI and IP.

fibre channel -

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

arbitrated loop

serially in a single loop circuit. The arbitrated loop topology supports all classes of service and

(FC-AL)

guarantees in order delivery of frames when the source and destination are on the same loop.

fibre channel

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

protocol for SCSI

command, data, and status information between a SCSI initiator and a SCSI target. Using FCP

(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.

File Transfer Protocol

gigabit interface

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

connector (GBIC)

characteristic of the media and interface, including drivers, transceivers, connectors, and

 

cables. Mounts on a FC adapter card and connects the interface card to a FC host. Also

 

referred to as a Physical Link Module (PLM).
