fiber optic cable fiber optics fibre Fibre Channel Fibre Channel adapter Fibre Channel drive enclosure Fibre Channel Loop field replaceable unit flush FMC form factor FPGA frequency FRU A transmission medium designed to transmit digital signals in the form of pulses of light. Fiber optic cable is noted for its properties of electrical isolation and resistance to electrostatic contamination. The technology where light is transmitted through glass or plastic (optical) threads (fibers) for data communication or signaling purposes. The international spelling that refers to the Fibre Channel standards for optical media. A data transfer architecture designed for mass storage devices and other peripheral devices that require very high bandwidth. See FCA. Fibre Channel Arbitrated Loop. The American National Standards Institute's (ANSI) document that specifies arbitrated loop topology operation. An enclosure that provides twelve-port central interconnect for Fibre Channel Arbitrated Loops following the ANSI Fibre Channel drive enclosure standard. See FRU. The act of writing dirty data from cache to a storage media. Fault Management Code. The HP Command View EVA display of the Enterprise Storage System error condition information. A storage industry dimensional standard for 3.5inch (89 mm) and 5.25inch (133 mm) high storage devices. Device heights are specified as low-profile (1inch or 25.4 mm), half-height (1.6inch or 41 mm), and full-height (5.25inch or 133 mm). Field Programmable Gate Array. A programmable device with an internal array of logic blocks surrounded by a ring of programmable I/O blocks connected together through a programmable interconnect. The number of cycles that occur in one second expressed in Hertz (Hz). Thus, 1 Hz is equivalent to one cycle per second. Field Replaceable Unit. A hardware element that can be replaced in the field. This type of replacement can require special training, tools, or techniques. Therefore, FRU procedures are usually performed only by an Authorized Service Representative. H HBA host Host Bus Adapter host computer host link indicator host ports host-side ports hot-pluggable hub Host Bus Adapter. See also FCA. A computer that runs user applications and uses (or can potentially use) one or more virtual disks created and presented by the controller pair. See FCA. See host. The HSV Controller display that indicates the status of the storage system Fibre Channel links. A connection point to one or more hosts through a Fibre Channel fabric. A host is a computer that runs user applications and that uses (or can potentially use) one or more of the virtual disks that are created and presented by the controller pair. See host ports. A method of element replacement whereby the complete system remains operational during element removal or insertion. Replacement does not interrupt data transfers to other elements. A communications infrastructure device to which nodes on a multi-point bus or loop are physically connected. It is used to improve the manageability of physical cables. I I/O module Input/Output module. The enclosure element that is the Fibre Channel drive enclosure interface to the host or controller. I/O modules are bus speed specific, either 1 Gb or 2 Gb. 173
