Glossary G G_Port Generic port. A port that can operate as either an E_Port or an F_Port. A port is defined as a G_Port when it is not yet connected or has not yet assumed a specific function in the fabric. gateway Gateway hardware merges SANs into a single fabric by establishing point-to-point E_Port connectivity between two Fibre Channel switches separated by a network with a protocol such as IP or SONET. GbE port Gigabit Ethernet (GbE) ports available on the SilkWorm 7500 and FR4-18i blade. These ports support the FCIP and Fibre Channel Routing Services features with link speeds up to 1 Gbit/sec. Each GbE port can support up to 8 FCIP tunnels. Each FCIP tunnel is represented and managed as a Fibre Channel E_Port. Fibre Channel Routing Services functionality can be used over the FCIP link. See also FCIP Tunneling Service. GBIC Gigabit interface converter. A removable serial transceiver module that allows gigabaud physical-level transport for Fibre Channel and gigabit Ethernet. GBICs have been replaced by SFPs in newer Brocade switches. See also SFP. GMT Greenwich Mean Time. An international time zone. Also known as "UTC." GoldenEye A Brocade 4-Gbit/sec switch ASIC. Used in the SilkWorm 200E. GUI Graphical user interface, in Brocade products: Web Tools, Fabric Manager., DMC, and so on. H HA High availability. A set of features in SilkWorm switches designed to provide maximum reliability and nondisruptive replacement of key hardware and software modules. Includes the HA manager and failover functionality in Fabric OS software and hardware features, such as redundant hot swappable CPs, fan FRUs, power supplies, and WWN cards. HA manager A daemon in Fabric OS that monitors processes in the fabric. If an error is detected, the HA manager will failover to the standby CP and reboot the primary CP. half duplex A mode of communication that allows a port to either transmit or receive frames at any time except simultaneously (with the exception of link control frames, which can be transmitted at any time). See also full duplex. hard address The AL_PA that an NL_Port attempts to acquire during loop initialization. hardwareenforced zoning Hardware-enforced zoning is specified when using the a homogenous zoning scheme, that is, when all members of a zone configuration are defined using the same method, either or WWNs, but not both. See also software enforced zoning. Hardware Translative Mode A method for achieving address translation. There are two hardware translative modes available to a QuickLoop-enabled switch: Standard Translative Mode and QuickLoop Mode. HBA Host bus adapter. The interface card in a server or workstation that allows an operating system to communicate on a Fibre Channel network. 14 Brocade Glossary Publication Number: 53-1000040-03
