This glossary contains terms related to disk storage subsystems.

 

 

Many of these terms are used in this manual.

 

 

ALPHANUMERIC

8b/10b encoding

Encoding scheme that converts each 8-bit data byte into a 10-bit

 

 

transmission character. Used to balance ones and zeros in high speed

 

 

transports.

 

 

A

Address identifier

Value used to identify source or destination of a frame.

AL_PA

Arbitrated Loop Physical Address. Unique 8-bit value assigned

 

 

during loop initialization to each port in an arbitrated loop.

Alias server

Fabric software facility that supports multicast group management.

ANSI

American National Standards Institute. Governing body for fibre

 

 

channel standards in the U.S.A.

API

Application Programming Interface. Defined protocol that allows

 

 

applications to interface with a set of services.

Arbitrated loop

A shared 100 MBps fibre channel transport structured as a loop.

 

 

Allows communication between ports without using a switch.

 

 

Requires successful arbitration by a port before a circuit is

 

 

established. Supports up to 126 devices and one fabric attachment.

 

 

This is similar to a shared bandwidth ring on a network.
