Glossary

Some terms used in the Fibre Channel industry are defined below. More information is available through the Fibre Channel Industry Association (www.fibrechannel.com), the Storage Area Networking Industry Association (www.snia.org) and the Fibre Channel Consortium (www.iol.unh.edu).

Term

Definition

fabric

A Fibre Channel switch or two or more Fibre Channel switches interconnected to

 

physically transmit data between any two N_Ports on a switch or switches.

failover

The substitution of a working system for one which has failed.

FC-AL

Fibre Channel Arbitrated Loop: A Fibre Channel network in which up to 126

 

systems and devices are connected in a loop topology, with each transmitter

 

connecting to the receiver of the device to its logical right. The Fibre Channel

 

Arbitrated Loop protocol used for transmission is different from Fibre Channel

 

switched and point to point protocols. Multiple FC-AL loops can be connected via

 

a fabric switch to extend the network.

firmware

Software stored in read-only memory (ROM) or programmable ROM (PROM).

 

Firmware is often responsible for the behavior of a system when it is first switched

 

on.

F_port

A port in the Fibre Channel fabric where a N_port may attach

FL-port

A port in the Fibre Channel fabric where a NL_port may attach in an arbitrated

 

loop

initiator device

A component which originates a command

LED

Light-emitting diode, a type of diode that emits light when current passes through

 

it. Visible LEDs are used as indicator lights on all sorts of electronic devices.

LUN

Logical Unit Number: a SCSI or Fibre Channel identifier of a device

NL port

a port attached to a node in Fibre Channel arbitrated loop or fabric loop

 

configurations

N_port

a port attached to a node used with point to point or fabric configurations

SCSI

Small Computer Systems Interface: a processor-independent standard for

 

system-level interface between a computer and intelligent devices including hard

 

disks, floppy disks, CD-ROM, printers, scanners, etc.

topology

logical layout of the parts of a computer system or network and their

 

interconnections
