ACS
Array Controller Software. The software component of the HS-series controller storage

performing the device-level operations required to satisfy the requests.
adapter
A device that converts the protocol and hardware interface of one bus type into that of
another without changing functionality of the bus.
AL_PA
Arbitrated loop physical address. A one-byte value used to identify a port in an Arbitrated
Loop topology.
ANSI
Pronounced “ann-see.” Acronym for the American National Standards Institute. An
organization who develops standards used voluntarily by many manufacturers within the
USA. ANSI is not a government agency.
arbitrated loop
In Fibre Channel Technology, a serial bus configuration in which device ports are
connected in a loop. Each port has a unique loop address and it communicates with other
ports on the loop by arbitrating for loop access. Loop addresses are assigned via cooperative
port intercommunication during loop initialization, which occurs any time the device
configuration on the loop is physically changed.
