Enabled zone configuration The currently enabled configuration of zones; only one configuration can be enabled at a time. Entry Fabric The basic Brocade software license that allows one E_Port per switch. EOF End of Frame. A group of ordered sets used to mark the end of a frame. Exchange The highest-level Fibre Channel mechanism used for communication between N_Ports, composed of one or more related sequences and working either uni- or bi-directionally. Exported device 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). EX_Port The type of E_Port used to connect a Multiprotocol Router to an edge fabric. An EX_Port follows standard E_Port protocols and supports FC-NAT but does not allow fabric merging across EX_Ports. Extended edge PID Format that 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. Extended Fabrics Optionally licensed Fabric OS feature that provides up to 500 km of switched fabric connectivity at full bandwidth over long distance. Extent A range of logical blocks within a logical unit (LU); the path name identifies both the LU of which the extent is part and the path used to access this extent. F Fabric A collection of Fibre Channel switches and directors and connected devices, such as hosts and storage. Fabric Application Platform A device that enables fabric-based storage applications such as mirroring, data migration, snapshots, and virtual tape. The Brocade Fabric Application Platform can run in a central location, process data at wire-speed, and reside in existing data paths. Fabric ID (FID) Unique identifier of a fabric in a metaSAN. Fabric Manager See Brocade Fabric Manager. Fabric port count The number of ports available for connection by nodes in a fabric. Fabric topology The arrangement of switches that form a fabric. Fabric Watch Optionally licensed Brocade software accessed through either the commandline interface or Brocade Web Tools; provides the ability to set thresholds for monitoring fabric conditions. Failover On a Brocade device, the process of activating the standby CP and transferring switch processing from the active CP so that traffic is not disrupted.
