Glossary extended edge PID Extended Fabrics extent extent pair This format generates the same PID for a port on switches with 16 or fewer ports as would native PID format, but it also supports up to 256 ports per domain. It should be used only in cases where you cannot upgrade devices to dynamic PID binding and you must not reboot your servers. Extended edge PID is supported in Fabric OS v2.6.x, v3.1.x, and v4.2.x. See also VC Encoded PID, native PID, and core PID. An optionally licensed Fabric OS feature that provides up to 500 km of switched fabric connectivity at full bandwidth over long distances. A range of logical blocks within a logical unit (LU). The path name identifies both the LU of which this extent is part and the path used to access this extents. See also DMM appliance. (ePair) Associates two extents in DMM: a source extent and an appropriate destination extent. This pair then identifies the migration locations to DMM. See also DMM appliance. F F_Port Fabric port. Fabric port on a switch to which an N_Port connects. See also N_Port, and Fx_Port. fabric One or more interconnected Fibre Channel switches. The term "fabric" refers to only the interconnected switches and not to devices connected to the fabric. See also cascade, SAN, and topology. fabric application platform A switching device that enables fabric-based storage applications to run within a fabric at wire-speed. The Brocade SilkWorm AP7420 is an example of a fabric application platform. See also DMM appliance. Fabric Fabric Manager is licensed Brocade software that resides on a host computer and enables fabric-wide Manager GUI management for multiple fabrics in geographically dispersed locations. Fabric mode 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. fabric name The unique identifier assigned to a fabric and communicated during login and port discovery. fabric port The number of ports available to connection SAN devices in a fabric. count fabric services Codes that describe the communication to and from any well-known address. fabric topology The arrangement of switches that form a fabric. Fabric Watch An optionally licensed Brocade software. Fabric Watch, accessed through either the command line or Web Tools, provides the ability to set thresholds for monitoring fabric conditions. failover On a SilkWorm director, the process of activating the standby CP and transferring switch processing to this CP. Typically when a failover occurs caused by a problem detected in the active CP, the standby CP is made active so that traffic is not disrupted. Multiple failovers occur during the firmware download process, because when new firmware is activated, the CP must be rebooted. FAN Fabric address notification. Retains the AL_PA and fabric address when a loop reinitializes, if the switch supports FAN. 10 Brocade Glossary Publication Number: 53-1000040-03
