PCI.

Peripheral control interconnect.

PCB.

Printed circuit board.

Performance Monitoring.

A feature that provides

error and performance information to the administrator
and user for use in storage management.

phantom address.

An arbitrated loop physical

address (AL_PA) value that is assigned to a device that
is not physically in the loop. Also known as phantom
AL_PA.

phantom device.

A device that is not physically in an

arbitrated loop, but is logically included through the use
of a phantom address.

PLDA.

See

private loop direct attach

PLOGI.

See

port login

PMC.

PCI mezzanine card.

P/N.

Part number.

point-to-point.

A Fibre Channel topology that employs

direct links between each pair of communicating
entities.

port login (PLOGI).

The port-to-port login process by

which initiators establish sessions with targets. See also

fabric login

port_name.

The unique identifier assigned to a Fibre

Channel port. Communicated during login and port
discovery.

POST.

See

power-on self-test

power-on self-test (POST).

A series of diagnostics

that are automatically run by a device when the power
is turned on.

primitive sequence.

A part of an ordered set that

indicates or initiates port states. See also

ordered set

primitive signal.

A part of an ordered set that

indicates events. See also

ordered set

private device.

A device that supports arbitrated loop

protocol and can interpret 8-bit addresses, but cannot
log into the fabric.

private loop.

An arbitrated loop that does not include

a participating fabric loop port (FL_port).

private loop direct attach (PLDA).

A subset of Fibre

Channel standards for the operation of peripheral
devices.

private NL_port.

A node loop port (NL_port) that

communicates only with other private NL_ports in the
same loop and does not log into the fabric.

protocol.

A defined method and a set of standards for

communication.

public device.

A device that supports arbitrated loop

protocol, can interpret 8-bit addresses, and can log into
the fabric.

public loop.

An arbitrated loop that includes a

participating fabric loop port (FL_port), and can contain
both public and private node loop ports (NL_ports).

public NL_port.

A node loop port (NL_port) that logs

into the fabric, can function within either a public or
private loop, and can communicate with either private or
public NL_ports.

QuickLoop.

(1) A feature that makes it possible to

allow private devices within loops to communicate with
public and private devices across the fabric through the
creation of a larger loop. (2) The arbitrated loop created
using this software. A QuickLoop can contain a number
of devices or looplets; all devices in the same
QuickLoop share a single arbitrated loop physical
address (AL_PA) space.

QuickLoop mode.

A hardware translative mode that

allows private devices to communicate with other private
devices across the fabric. See also

hardware translative

mode

and

standard translative mode

RAID.

See

redundant array of independent disks

RAM.
