E_Port EE_Credit EIA rack enabled zone configuration end-to-end flow control error exchange F_Port fabric fabric name FCIA FCP FCS switch Fibre Channel fill word FLOGI FL_Port frame FRU FS FSP FSPF Fx_Port Expansion port. A type of switch port that can be connected to an E_Port on another switch to create an ISL. See also U_Port. End-to-end credit. The number of receive buffers allocated by a recipient port to an originating port. Used by Class 1 and Class 2 services to manage the exchange of frames across the fabric between source and destination. An equipment storage rack that meets the standards set by the EIA (Electronics Industry Association). The currently enabled configuration of zones. Only one configuration can be enabled at a time. See also zone, zone configuration. A facility that governs flow of class 1 and class 2 frames between N_Ports. With respect to FC, a missing or corrupted frame, time-out, loss of synchronization, or loss of signal (link error). The highest-level FC mechanism used for communication between N_Ports. Composed of one or more related sequences; can work in one or both directions. Fabric port. A port that is able to transmit under fabric protocol and interface over links. Can be used to connect an N_Port to a switch. See also U_Port. An FC network containing two or more switches in addition to hosts and devices. May also be called a switched fabric. The unique identifier assigned to a fabric and communicated during login and port discovery. Fibre Channel Industry Association. An international organization of FC industry professionals. Provides oversight of ANSI and industry standards. Fibre Channel Protocol. Mapping of protocols onto the FC standard protocols. For example, SCSI FCP maps SCSI-3 onto FC. Fabric Configuration Server switch. One or more designated HP switches that store and manage the configuration and security parameters for all switches in the fabric. The primary protocol for building SANs to transmit data between servers, switches, and storage devices. Unlike IP and Ethernet, Fibre Channel is designed to support the needs of storage devices of all types. It is a high-speed, serial, bidirectional, topology-independent protocol, and is a highly scalable interconnection between computers, peripherals, and networks. An IDLE or ARB ordered set that is transmitted during breaks between data frames to keep the link active. The process by which an N_Port determines whether a fabric is present and, if so, exchanges service parameters with it. See also PLOGI. Fabric loop port. A port that is able to transmit under fabric protocol and has arbitrated loop capabilities. Can also be used to connect an NL_Port to a switch. See also U_Port. The Fibre Channel structure used to transmit data between ports. Consists of a start-of-frame delimiter, header, optional headers, data payload, cyclic redundancy check, and end-of-frame delimiter. There are two types of frames: link control frames and data frames. See also packet. Field-replaceable unit. A component that can be replaced on site. Fibre Channel Service. A service that is defined by FC standards and exists at a well-known address. The Simple Name Server, for example, is an FC service. See also SNS. Fibre Channel Service Protocol. The common protocol for all fabric services; it is transparent to the fabric type or topology. Fabric shortest path first. HP routing protocol for FC switches. A fabric port that can operate as an F_Port or FL_Port. 46 Glossary
