Glossary 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. Route As applies to a fabric, the communication path between two switches. May also apply to the specific path taken by an individual frame, from source to destination. Routing The assignment of frames to specific switch ports, according to frame destination. RR_TOV Resource Recovery Time-out Value; the minimum time a target device in a loop waits after a LIP before logging out a SCSI initiator. RSCN Registered State Change Notification; a switch function that allows notification of fabric changes to be sent from the switch to specified nodes. RX_ID Responder Exchange Identifier. A 2-byte field in the frame header used by the responder of the Exchange to identify frames as being part of a particular exchange. SAN Storage Area Network; a network of systems and storage devices that communicate using Fibre Channel protocols. See also Fabric. Sequence A group of related frames transmitted in the same direction between two N_Ports. Service Rate The rate at which an entity can service requests.
