HP AA979A - StorageWorks SAN Switch 2/8V Installation Manual page 119

A fibre channel topology that employs direct links between each pair of
point-to-point
communicating entities.
The metal casing extending out of the fibre channel port on the switch, and into which
port cage
a GBIC or SFP transceiver can be inserted.
The unique identifier assigned to a fibre channel port. Communicated during login
Port_Name
and port discovery.
Power On Self-Test. A series of tests run by a switch after it is powered on.
POST
Primary fabric configuration server switch. The switch that actively manages the
primary FCS switch
configuration and security parameters for all switches in the fabric.
An arbitrated loop that does not include a participating FL_Port.
private loop
An NL_Port that communicates only with other private NL_Ports in the same loop and
private NL_Port
does not log into the fabric.
A device that supports arbitrated loop protocol, can interpret 8-bit addresses, and can
public device
log into the fabric.
An arbitrated loop that includes a participating FL_Port, and may contain both public
public loop
and private NL_Ports.
An NL_Port that logs into the fabric, can function within either a public or a private
public NL_Port
loop, and can communicate with either private or public NL_Ports.
Q
A group of four adjacent ports that share a common pool of frame buffers.
quad
R
Resource allocation time-out value. The maximum time a frame can be delayed in the
R_A_TOV
fabric and still be delivered.
Redundant Array Of Independent Disks. A collection of disk drives that appear as a
RAID
single volume to the server and are fault tolerant through mirroring or parity checking.
The rate at which requests arrive at a servicing entity.
request rate
As applies to a fabric, the communication path between two switches. May also

apply to the specific path taken by an individual frame, from source to destination.
The assignment of frames to specific switch ports, according to frame destination.
routing
Resource recovery time-out value. The minimum time a target device in a loop waits
RR_TOV
after a LIP before logging out a SCSI initiator.
