FC device

A device that uses Fibre Channel communications.

FC port

An opening at the back of the network storage router that provides a fiber optic connection

between the FC adapter and the FC host.

FC-SCSI hardware

path ID

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

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 -

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.

File Transfer Protocol

gigabit interface

connector (GBIC)

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 network storage router to a FC host.

Also referred to as a Physical Link Module (PLM).

host bus adapter

(HBA)

See FC Adapter.

HVD

High Voltage Differential

ID

Numerical identifier

indexed addressing A menu name. It allows for generic Fibre Channel host bus adapters to access SCSI devices

attached to the network storage router using a table which is indexed by sequential LUN

values.
