G_Port Gateway GBIC Gbps GBps Half-duplex Hard address HBA Hub Idle Initiator IOD ISL IU 46 Generic Port. Port that can operate either as E_Port or F_Port. Ports are defined as G_Ports when disconnected or have not assumed specific function within fabric. IP address assignment that provides translation for incompatible networks. For example, ATM gateway can connect a fibre channel link to an ATM connection. Gigabit Interface Converter. Removable serial transceiver module that allows gigabit physical-layer transport for fibre channel. Gigabits (1,062,500,000 bits) per second. Gigabytes (1,062,500,000 bytes) per second. Mode of communication that allows a port to either transmit or receive frames, but not both simultaneously. The only exception is link control frames, which can be transmitted at any time. See also Full-duplex. The AL_PA that an NL_Port attempts to acquire during loop initialization. Host Bus Adapter. Interface card between a server or workstation bus and the fibre channel network. Similar to a network interface card. Fibre channel wiring concentrator that collapses loop topology into physical star topology. Nodes are automatically added when active and removed when inactive. Continuous transmission of an ordered set when no data is being transmitted to maintain an active fibre channel link and synchronization. See also Fill word. Server or workstation that initiates communications with storage devices over a fibre channel network. See also Target. In Order Delivery. A parameter that, when set, guarantees that frames are delivered in order if possible, otherwise frames are dropped. Interswitch Link. Fibre channel link from the E_Port of one switch to the E_Port of another. Information Unit. An individual set of information as defined by higher level process protocol definition, or upper-level protocol mapping. QuickLoop User's Guide
