APPENDIX E

Glossary

AL_PA or Arbitrated Loop

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

Physical Address

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.
