defined zone configuration directory service DLS domain ID E_D_TOV 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 The set of all zone objects defined in the fabric. May include multiple zone configurations. See also zone, zone configuration. See SNS. Dynamic load sharing. Dynamic distribution of traffic over available paths. Allows for recomputing of routes when an Fx_Port or E_Port changes status. Unique identifier used in routing frames for all switches in a fabric. Usually assigned by the principal switch, but can be assigned manually. The domain ID for an HP switch can be any integer between 1 and 239. The default domain ID is usually 1. Error-detect time-out value. The minimum time a target waits for a sequence to complete before initiating recovery. Can also be defined as the maximum time allowed for a round-trip transmission before an error condition is declared. 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. A 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. Among other things, 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. 58 Glossary
