The address of a Fibre Channel node in an arbitrated loop. Arbitration The process of selecting one respondent from a collection of several candidates that request service at the same time.
  • Page 72 Glossary Boot BIOS Software coded into the chips on the HBA. A special program used to boot and control the computer. Broadband In data transmission, it denotes transmission facilities capable of handling frequencies greater than those required for high-grade voice communications. The higher frequency allows the carrying of several simultaneous channels.
  • Page 73 Glossary Duplex Transmission Transmission in both directions, either one direction at a time (half duplex) or both directions simultaneously (full duplex). Fabric A Fibre Channel interconnection method that allows multiple simultaneous and concurrent data transfers between multiple hosts and/or storage devices connected with a multi-port hub. FC-AL Abbreviation for Fibre Channel Arbitrated Loop, an interconnection scheme that supports from 1 to 126 ports on a loop in a shared medium topology.
  • Page 74 Glossary GB/s Gigabytes per second or 1,073,741,824 bytes per second. A reference to processing speed. Gigabit Link Module. A transmitter and receiver that provides high-speed serial links, enabling continuous throughput in each direction simultaneously. Host Adapter Module (HAM) A HAM is the driver component used to drive specific HBA hardware in the NetWare Peripheral Architecture (NPA).
  • Page 75 Glossary Light Emitting Diode (LED) A device used in a transmitter to convert information from electrical to optical form. It typically has a large spectral width. Lightwaves Electromagnetic waves in the region of optical frequencies. The term “light” was originally restricted to radiation visible to the human eye, with wavelengths between 400 and 700 nanometers (nm).
  • Page 76 Glossary Mode A term used to describe a light path through a fiber, as in multi-mode or single-mode. Multi-initiators Two different Fibre Channel HBAs in one arbitrated loop sharing the same storage devices, but not communicating with each other. Multi-Mode Fiber An optical waveguide in which light travels in multiple modes.
  • Page 77 Glossary Optical Waveguide Dielectric waveguide with a core consisting of optically transparent material or low attenuation (usually silica glass) and with cladding consisting of optically transparent material of lower refractive index than that of the core. It is used for the transmission of signals with lightwaves and is frequently referred to as fiber.
  • Page 78 Glossary Simplex Transmission Transmission in one direction only. Single-Mode Fiber An optical waveguide (or fiber) with a small core diameter in which only a single mode is capable of propagation. This type of fiber is particularly suitable for wideband transmission over large distances, since its bandwidth is limited only by chromatic dispersion.
