arbitrated loop
An encoding scheme that converts each 8-bit byte into 10 bits. Used to balance
ones and zeroes in high-speed transports.
Abort Basic Link Service. Also called Abort Sequence
Accept link service reply. The normal reply to an Extended Link Service request
(such as FLOGI), indicating that the request has been completed.
A process by which contending nodes are guaranteed access to an arbitrated
loop.
A Fibre Channel connection that allows copper cabling up to 33 meters (36
yards) between devices.
A 24-bit or 8-bit value used to identify the source or destination of a frame.
See also D_ID and S_ID.
Arbitrated-loop physical address. A unique 8-bit value assigned during loop
initialization to a port in an arbitrated loop.
Arbitrated-loop timeout value. Twice the amount of time it would take for a
transmission word to propagate around a worst-case loop. The default value is
15 milliseconds.
A logical grouping of elements in a fabric. An alias is a collection of port
numbers and connected devices, used to simplify the entry of port numbers and
WWNs when creating zones.
An address identifier recognized by a port in addition to its standard identifier.
An alias address identifier can be shared by multiple ports.
See also alias.
An AL_PA value recognized by an L_Port in addition to the AL_PA assigned to
the port.
See also AL_PA.
A name assigned to one device or group of devices to allow an intuitive name
structure for a zone object.
See also zone object.
A fabric software facility that supports multicast group management.
American National Standards Institute. A private, nonprofit organization that
administers and coordinates voluntary standards in the United States. ANSI
has a number of working committees. The X3T11 committee is principally
responsible for Fibre Channel interface standards.
Arbitrative primitive signal. Applies only to an arbitrated-loop topology.
Transmitted as the fill word by an L_Port to indicate that the port is arbitrating
access to the loop.
A shared 100-Mbps Fibre Channel transport structured as a loop. Can support
up to 126 devices and one fabric attachment.
See also topology.
