SilkWorm 3800 Hardware Reference
An encoding scheme that converts each 8-bit byte into 10 bits. Used to balance
ones and zeros in high-speed transports.
A 24-bit or 8-bit value used to identify the source or destination of a frame.
Arbitrated loop physical address. A unique 8-bit value assigned during loop
initialization to a port in an arbitrated loop.
An alternate name for an element or group of elements in the fabric. Aliases can
be 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 may 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 fabric software facility that supports multicast group management.
American National Standards Institute. The governing body for fibre channel
standards in the U.S.A.
Application programming interface. A defined protocol that allows applications
to interface with a set of services.
A shared 100 MBps fibre channel transport structured as a loop. Can support up to
126 devices and one fabric attachment. See also topology.
Application specific integrated circuit.
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.
Arbitration wait time-out value. The minimum time an arbitrating L_Port waits
for a response before beginning loop initialization.
Backup fabric configuration server switch. The switch or switches assigned as
backup in case the primary FCS switch fails. See also FCS switch, primary FCS
switch.
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 link or system. See also throughput.
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.
