APPENDIX E

Glossary

 

 

 

 

 

AL_PA or Arbitrated

A one-byte value used to identify a port in an Arbitrated Loop topology.

 

 

Loop Physical Address

The value of the AL_PA corresponds to bits 7:0 of the 24-bit Native

 

 

 

Address Identifier.

 

 

 

 

 

 

Arbitration

The process of selecting one respondent from a group requesting

 

 

 

service at the same time.

 

 

 

 

 

 

Close (CLS)

An Arbitrated Loop protocol used to terminate a loop circuit.

 

 

 

 

 

 

Current Fill Word

The fill word that the Loop Port State Machine uses when a fill word is to

 

 

 

be transmitted.

 

 

 

 

 

 

Duplex Cable

Two fibers in one cable suitable for duplex transmission.

 

 

 

 

 

 

Fiber Optics

Light transmission through optical fibers for communication or signaling

 

 

 

 

 

 

Fibre Channel

Fibre Channel is a data transfer interface technology that maps several

 

 

 

common transport protocols including IP and SCSI, allowing it to merge

 

 

 

high-speed I/O and networking functionality in a single connectivity

 

 

 

technology. Fibre channel is an open standard as defined by ANSI and

 

 

 

OSI standards and operates over copper and fiber optic cabling at

 

 

 

distances of up to 10 Kilometers. It is unique in its support of multiple

 

 

 

interoperable topologies including point-to-point, arbitrated-loop and

 

 

 

switching and it offers several qualities of service for network

 

 

 

optimization. With its large packet sizes, Fibre Channel is ideal for

 

 

 

storage, video, graphic and mass data transfer applications.

 

 

 

 

 

 

LED

Light-Emitting Diode. A status indicator on a switch.

 

 

 

 

 

 

Gb/s

Gigabits per second.

 

 

 

 

 

 

Node

An entity with one or more N_Ports or NL_Ports.

 

 

 

 

 

 

Open (OPN)

An Arbitrated Loop protocol used to establish a loop circuit.

 

 

 

 

 

 

Protocol

A data transmission convention which may include timing, control,

 

 

 

formatting, error detection with correction and data representation.

 

 

 

 

 

 

SCSI

Small Computer System Interface. Standard interface for storage

 

 

 

modules.

 

 

 

 

 

 

SFP

Small Form-Factor Pluggable transceiver. These transceivers are fully

 

 

 

compliant with FC-PI and MSA standards and occupy less than half the

 

 

 

board space of the existing GBIC products.

 

 

 

 

 

 

Topology

The logical and/or physical arrangement of stations on a network. Fibre

 

 

 

Channel topologies include point-to-point, Arbitrated Loop, and switched

 

 

 

fabric.

 

 

 

 

 

 

Transceiver

A device that converts one form of signaling to another for both

 

 

 

transmission and reception. SFPs and GBICs are transceivers.
