8b/10b

An encoding scheme that converts each 8-bit byte into 10 bits. Used to balance

Encoding

ones and zeros in high-speed transports.

Address

A 24-bit or 8-bit value used to identify the source or destination of a frame.

Identifier

 

Advanced

A software product that provides error and performance information to the

Performance

administrator and end user for use in storage management.

Monitoring

 

AL_PA

Arbitrated Loop Physical Address; a unique 8-bit value assigned during loop

 

initialization to a port in an arbitrated loop.

Alias Address Identifier

Alias AL_PA

An address identifier recognized by a port in addition to its standard identifier. An alias address identifier may be shared by multiple ports.

An AL_PA value recognized by an L_Port in addition to the AL_PA assigned to the port. See also AL_PA.

Alias Server

A fabric software facility that supports multicast group management.

ANSI

American National Standards Institute; the 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

A shared 100 MBps Fibre Channel transport structured as a loop. Can support up

Loop

to 126 devices and one fabric attachment. See also Topology.

ASIC

Application Specific Integrated Circuit.

ATM

Asynchronous Transfer Mode; a transport used for transmitting data over LANs

 

or WANs that transmit fixed-length units of data. Provides any-to-any

 

connectivity, and allows nodes to transmit simultaneously.

AW_TOV

Arbitration Wait Time-out Value; the minimum time an arbitrating L_Port waits

 

for a response before beginning loop initialization.

Bandwidth

The total transmission capacity of a cable, link, or system. Usually measured in

 

bps (bits per second). May also refer to the range of transmission frequencies

 

available to a network. See also Throughput.

BB_Credit

Buffer-to-buffer credit; the number of frames that can be transmitted to a directly

 

connected recipient or within an arbitrated loop. Determined by the number of

 

receive buffers available. See also Buffer-to-buffer Flow Control, EE_Credit.

Beginning

The disparity at the transmitter or receiver when the special character associated

Running

with an ordered set is encoded or decoded. See also Disparity.
