Glossary - IBM 3534-F08 Installation And User Manual

Glossary

This glossary provides definitions for the
fibre-channel and switch terminology that the IBM
3534 Model F08 uses.
This glossary includes selected terms and
definitions from:
v Information Technology Vocabulary by
Subcommittee 1, Joint Technical Committee 1,
of the International Organization for
Standardization and the International
Electrotechnical Commission (ISO/IEC
JTC1/SC1). Definitions are identified by the
symbol (I) after the definition; definitions taken
from draft international standards, committee
drafts, and working papers by ISO/IEC
JTC1/SC1 are identified by the symbol (T) after
the definition, indicating that final agreement
has not yet been reached among the
participating National Bodies of SC1.

8B/10B encoding. An algorithm for encoding data for
transmission in which each 8-bit data byte is converted
to a 10-bit transmission character. 8B/10B encoding
supports continuous transmission with a balanced
number of ones and zeros in the code stream and
detects single bit transmission errors.
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. An address value used to identify
the source (S_ID) or destination (D_ID) 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. One or more address
identifiers which can be recognized by a node port
(N_port) in addition to its N_port identifier. Alias address
identifiers are used to form groups of N_ports so that
frames can be addressed to a group rather than to
individual N_ports.
alias AL_PA. An arbitrated loop physical address
(AL_PA) value recognized by a loop port (L_port) in
addition to the AL_PA assigned to the port. See also
arbitrated loop physical address.
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 set of
run-time routines or system calls that allows an
application program to use a particular service provided
by either the operating system or another licensed
program.
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
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. 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. See also arbitrated loop.
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.
