Pulse-code modulation. A standard method of encoding analog audio signals in digital form. An HP StorageWorks switch feature that monitors port traffic and includes frame counters, SCSI read monitors, SCSI write monitors, and other types of monitors. An AL_PA value that is assigned to a device that is not physically in the loop. Also called phantom AL_PA. A device that is not physically in an arbitrated-loop but is logically included through the use of a phantom address. Port identifier. As defined in FC-FG, bits 7 through 0 of an address identifier. See also core PID. Public key infrastructure. An infrastructure that is based on public key cryptography and CA and that uses digital certificates. See also CA, digital certificate, and public key cryptography. Public key 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. Programmable logic array. A small FPD. See also FPD. Programmable logic device. Also called FPD. See also FPD. Private loop direct-attached. A technical report specifying a logical loop. Port login. The port-to-port login process by which initiators establish sessions with targets. See also FLOGI. A Fibre Channel topology that employs direct links between each pair of communicating entities. See also topology. In an HP StorageWorks switch environment, an SFP or GBIC receptacle on a switch to which an optic cable for another device is attached. In Fabric OS, a port address can be defined by a domain and port number combination or by area number. In an ESCON Director, an address is used to specify port connectivity parameters and to assign link addresses for attached channels and control units. See ESCON. The metal casing extending out of the optical port on the switch, into which the SFP can be inserted. A hardware component that provides a platform for field-replaceable, hot swappable ports. A group of adjacent ports that share a common pool of frame buffers for long-distance connections. A process that defines a zone member by domain,port, which is the physical port to which the member is connected. See also zone member and WWN-level zoning. A record of all activity on a switch, kept in volatile memory. The output when the portLogDump command is used to read the port log. Fabric OS 5.x master glossary 23
