adapter
The board that interfaces between the
host system and the target devices.
Adapter is synonymous with host bus
adapter (HBA), host adapter, and adapter
board.
adapter port
A port on the adapter board.
adapter port beacon
An LED on the adapter. Flashing it enables

arbitrated loop
A circular (ring) topology (versus
point-to-point) where two or more
port s
can be interconnected, but only two ports
can communicate at a time. All communi-
cation passes through all ports connected
to the loop.
bandwidth
A measure of the volume of data that can
be transmitted at a given transmission
rate. A 1-Gbps/2-Gbps Fibre Channel
port
can transmit or receive at nominal rates of
1- or 2-Gbps, depending on the device to
which it is connected. This corresponds to
actual bandwidth values of 106MB and
212MB, respectively.
