Glossary-7

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 Hardware that connects incompatible networks by providing translation for both hardware and

software. For example, an ATM gateway can be used to connect a Fibre Channel link to an ATM

connection.

GBIC Gigabit interface converter. A removable serial transceiver module that allows gigabaud physical-level

transport for Fibre Channel and gigabit Ethernet.

Gbit/sec Gigabits per second (1 Gbit/sec = 1,062,500,000 bits/second, 2 Gbit/sec = 2, 125,000,000 bits/seconc).

GB/sec Gigabytes per second.

GLM Gigabit Link Module. A semitransparent transceiver that incorporates serializing/deserializing

functions.

GMT Greenwich Mean Time. An international time zone. Also known as "UTC."

GUI A graphic user interface, such as Brocade Advanced Web Toolsarbitrated-loop topology and Brocade

Fabric Manager.

HA High availability. A set of features in Brocade SilkWorm switches that is designed to provide maximum

reliability and nondisruptive replacement of key hardware and software modules.

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.

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 between a server or workstation bus and the Fibre Channel

network.

hop count The number of ISLs a frame must traverse to get from its source to its destination.

host A computer system that provides end users with services like computation and storage access.

hot swappable A hot swappable component can be replaced while the power is on.

HTTP Hypertext Transfer Protocol. The standard TCP/IP transfer protocol used on the World Wide Web.
