Glossary Port_Name The unique identifier assigned to a Fibre Channel port. Communicated during login and port discovery. POST Power On Self-Test; a series of tests run by a switch after it is turned on. 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 FL_Port. Private NL_Port An 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 NL_Port An NL_Port that logs into the fabric, can function within either a public or a private loop, and can communicate with either private or public NL_Ports. Public Device A device that can log into the fabric and support 20-bit addresses (or has 20-bit phantom addresses created for it by the switch). Public Loop An arbitrated loop that includes a participating FL_Port, and may contain both public and private NL_Ports. QuickLoop 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. May also refer to 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 AL_PA space. R_A_TOV Resource Allocation Time-out Value; the maximum time a frame can be delayed in the fabric and still be delivered. hp StorageWorks SAN Switch 2/8 Installation Guide 97
