Glossary - IBM F16 User Manual

Glossary

This glossary provides definitions for the
fibre-channel and switch terminology that the IBM
2109 Model F16 uses.
This glossary defines technical terms and
abbreviations that this book uses. If you do not

This glossary also includes terms and definitions
from:
v American National Standard Dictionary for
Information Systems, ANSI X3.172-1990,
copyright 1990 by the American National
Standards Institute (ANSI). You can purchase
copies from the American National Standards
Institute, 11 West 42nd Street, New York, New

8b/10b encoding. An encoding scheme that converts
each 8-bit byte into 10 bits. Used to balance ones and
zeros in high-speed transports
access control list (ACL). A list that specifies the
users and groups allowed to access a particular file or
directory.

ACL. See access control list.
address identifier. A 24-bit or 8-bit value used to
identify the source or destination of a frame.
Address Resolution Protocol (ARP). In the Internet
suite of protocols, the protocol that dynamically maps an
Internet Protocol (IP) address to an address used by a
supporting metropolitan or local area network such as
Ethernet or token-ring.
alias address identifier. An address identifier
recognized by a port in addition to its standard identifier.
An alias address identifier can be shared by multiple
ports.
alias server. A fabric software facility that supports
multicast group management.
AL_PA. See arbitrated loop physical address.
American National Standards Institute (ANSI). An
organization that establishes the procedures by which
accredited organizations create and maintain voluntary
industry standards in the United States.
ANSI. See American National Standards Institute.
API. See application programming interface.
application programming interface (API). A defined
protocol that allows applications to interface with a set
of services.
application-specific integrated circuit (ASIC). In
computer chip design, an integrated circuit created by
first mounting an array of unconnected logic gates on a
substrate and later connecting these gates in a a
particular configuration for a specific application. This
design approach allows chips for a variety of
applications to be made from the same generic gate
array, thereby reducing production costs.
ARB. See arbitrate primitive signal.
arbitrate primitive signal (ARB). A primitive signal
that is transmitted as the fill word by a loop port (L_port)
to indicate that the L_port is arbitrating to access to the
loop. Applies only to the arbitrated loop topology.
arbitrated loop. A shared 100 MBps Fibre Channel
transport structured as a loop and supporting up to 126
devices and one fabric attachment. A port must
successfully arbitrate before a circuit can be
established.
arbitrated loop physical address (AL_PA). An 8-bit
value used to identify a participating device in an
arbitrated loop.
