PCBA Printed circuit board assembly.
PCM Pulse-code modulation. A standard method of encoding analog audio signals
in digital form.
Performance
Monitoring
An HP StorageWorks switch feature that monitors port trafficandincludesframe
counters, SCSI read monitors, SCSI write monitors, and other types of monitors.
phantom address An AL_PA value that is assigned to a device that is not physically in the loop.
Also called 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 add ress.
PID Por t identifier. A s defined in FC-FG, bits 7 through 0 of an address identifier.
See also core PID.
PKI Public key infrastructure. An infrastructure that is based on public key
cryptogra
phy and CA and that uses digital certificates.
See also CA
, digital certificate,andpublic key cryptography.
PKI certification
utility
Public ke y infrastructure certification utility. A utility that makes it possible to
collect certificate requests from switches and to load certificates to switches.
See also digital certificate, PKI.
PLA Programmable logic array. A small FPD.
See also FPD.
PLD Programmable logic device. Also called FPD.
See also FPD.
PLDA Private l
oop direct-attached. A technical report specifying a logical loop.
PLOGI Port login. The por t-to-port login process by which initiators establish sessions
with targets.
See also FLOGI.
point-to-point A Fibre Channel topology that employs direct links between each pair of
communicating entities.
See also topology.
port In an HP StorageWorks switch environment, an SFP or G BIC receptacle on a
switch to which an optic cable for another device is attached.
port address In Fabric OS, a port address can be defined by a domain and por t number
combination or by area number. In an ESCON Director, an address is used to
speci
fy port connectivity parameters and to assign link addresses for attached
channels and control units.
See ESCON.
port cag e The metal casing extending out of the optical port on the switch, into which the
SFP can be inserted.
port card A hardware component that provides a platform for field-replaceable, hot
swappable ports.
port group A group of adjacent ports that share a common pool of frame buffers for
long-distance connections.
port-level zoning Aprocessthatdefines a zone member by domain,port,whichisthephysical
port to which the memb er is connected.
See a
lso zone member and WW N -level zoning.
port log A record of all activity on a switch, kept in volatile memor y.
port log dump TheoutputwhentheportLogDump comm and is used to read the port log.
