Glossary GBIC Gigabit interface converter. A removable serial transceiver module that allows gigabaud physical-level transport for Fibre Channel and gigabit Ethernet. Typically refers only to the SC-form factor transceivers. See also SFP. Gbps Gigabits per second (1,062,500,000 bits/second). GBps Gigabytes per second (1,062,500,000 bytes/second). Half-duplex A mode of communication that allows a port to either transmit or receive frames at any time, but not 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. The following two hardware translative modes are available to a QuickLoop-enabled switch: ■ Standard Translative Mode: Allows public devices to communicate with private devices that are directly connected to the fabric. ■ QuickLoop Mode: Allows initiator devices to communicate with private or public devices that are not in the same loop. HBA Host Bus Adapter. The interface card between a server or workstation bus and the Fibre Channel network. High Availability An attribute of equipment that identifies it as being capable of conducting customer operations well in excess of 99% of the time. Typically High Availability is identified by the number of nines in that percentage. "Five Nines" means the equipment is rated as being capable of conducting customer operations 99.999% of the time without failure. 86 Zoning Version 3.1.x/4.1.x User Guide
