end-to-end flow control entry fabric EOF error EVMd EX_Port exchange exported device F_BSY F_Port F_RJT fabric fabric application platform Fabric Manager Fabric Mode fabric name fabric port count fabric services fabric topology Fabric Watch failover Governs flow of Class 1 and 2 frames between N_Ports. See also EE_Credit. The basic HP software license that allows one E_Port per switch. End of frame. A group of ordered sets used to mark the end of a frame. As it applies to the Fibre Channel industry, a missing or corrupted frame, timeout, loss of synchronization, or loss of signal (link errors). See also loop failure. Event management database. Delivers FDMI-related events. A type of E_Port that connects an FC router to an edge fabric. EX_Ports limit the scope of fabric services scope but provide device connectivity using FC-NAT. The highest-level Fibre Channel mechanism used for communication between N_Ports. Composed of one or more related sequences, it can work in either one or both directions. A device that has been mapped between fabrics (a host or storage port in one edge fabric can be exported to any other fabric by using LSAN zoning). Fabric port busy frame. A frame issued by the fabric to indicate that a frame cannot be delivered because the fabric or destination N_Port is busy. 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 FL_Port, Fx_Port. Fabric port reject frame. A frame issued by the fabric to indicate that delivery of a frame is being denied, perhaps because a class is not supported, there is an invalid header, or no N_Port is available. A collection of Fibre Channel switches and devices, such as hosts and storage. Also referred to as a switched fabric. See also cascade, SAN, topology. A device that enables fabric-based storage applications such as mirroring, data migration, snapshots, and virtual tape. The HP StorageWorks Fabric Application Platform can run in a central location, process data at wire-speed, and reside in existing data paths. An optionally licensed HP software. Fabric Manager is a GUI that allows for fabric-wide administration and management. Switches can be treated as groups, and actions such as firmware downloads can be performed simultaneously. One of two possible modes for an L_Port, in which the L_Port is connected to another port that is not loop capable, using fabric protocol. The unique identifier assigned to a fabric and communicated during login and port discovery. The number of ports available for connection by nodes in a fabric. Codes that describe the communication to and from any well-known address. The arrangement of switches that form a fabric. An optionally licensed HP software. Fabric Watch can be accessed through either the command line or Advanced Web Tools, and it provides the ability to set thresholds for monitoring fabric conditions. Describes the Core Switch 2/64 process of one CP passing active status to another CP. A failover is nondisruptive. 802 Glossary
