node

An FC device that contains an N_Port or NL_Port.

non-participating

A mode in which an L_Port in a loop is inactive and cannot arbitrate or send frames,

mode

but can retransmit any received transmissions. This mode is entered if there are more

 

than 127 devices in a loop and an AL_PA cannot be acquired. See alsoL_Port, AL_PA.

Nx_Port

A node port that can operate as an N_Port or NL_Port.

Onboard

The HP BladeSystem Onboard Administrator (OA) is the enclosure management

Administrator (OA)

processor, subsystem, and firmware base used to support the HP BladeSystem c7000

 

and all the managed devices contained within the enclosure.

packet

A set of information transmitted across a network.

participating mode A mode in which an L_Port in a loop has a valid AL_PA and can arbitrate, send frames,

 

and retransmit received transmissions.

path selection

The selection of a transmission path through the fabric. HP switches use the FSPF

 

protocol for transmission path selection.

phantom address

An AL_PA value assigned to a device that is not physically in the loop. Also known as

 

phantom AL_PA. See also AL_PA,phantom device.

phantom device

A device that is not physically in an arbitrated loop but is logically included through the

 

use of a phantom address. See also phantom address.

PLOGI

Port login. The port-to-port login process by which initiators establish sessions with

 

targets. See also FLOGI.

point-to-point

An FC topology that employs direct links between each pair of communicating entities.

 

See also buffer-to-bufferflow control.

port cage

The metal casing extending out of the FC port on the switch and into which a GBIC or

 

SFP transceiver can be inserted.

Port_Name

The unique identifier assigned to an FC port. It is communicated during login and port

 

discovery.

POST

Power-on self-test. A series of diagnostic tests run by a switch after it is powered on.

primary FCS

Primary Fabric Configuration Server switch. The switch that actively manages the

switch

configuration and security parameters for all switches in the fabric.

private loop

An arbitrated loop that does not include a participating FL_Port.

private NL_Port

An NL_Port that communicates only with other private NL_Ports in the same loop and

 

does not log in to the fabric.

public device

A device that supports arbitrated loop protocol, can interpret 8-bit addresses, and can

 

log in to the fabric. See also arbitrated loop.

public loop

An arbitrated loop that includes a participating FL_Port and may contain both public

 

and private NL_Ports. See also arbitrated loop.

public NL_Port

An NL_Port that logs in to the fabric, can function within a public or private loop, and

 

can communicate with private or public NL_Ports. See also private loop.

quad

A group of four adjacent ports that share a common pool of frame buffers.
