FCC Federal Communications Commission. The federal agency responsible for
establishing standards and approving electronic devices within the United States.
FCP Fibre Channel Protocol. The mapping of SCSI-3 operations to Fibre Channel.
fiber The optical media used to implement Fibre Channel.
fiber optics The technology where light is transmitted through glass or plastic (optical) threads
(fibers) for data communication or signaling purposes.
fiber optic cable 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.
fibre The international spelling that refers to the Fibre Channel standards for optical
media.
Fibre Channel A data transfer architecture designed for mass storage devices and other
peripheral devices that require very high bandwidth.
Fibre Channel
adapter See FCA .
Fibre Channel
Loop An enclosure that provides twelve-port central interconnect for Fibre Channel
Arbitrated Loops following the ANSI Fibre Channel drive enclosure standard.
field replaceable
unit See FRU .
flush The act of writing dirty data from cache to a storage media.
FMC Fault Management Code. The HP Command View EVA display of the Enterprise
Storage System error condition information.
form factor 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).
FPGA 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.
frequency The number of cycles that occur in one second expressed in Hertz (Hz). Thus, 1
Hz is equivalent to one cycle per second.
FRU 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.
Gb Gigabit. A measurement of the rate at which the transfer of bits of data occurs.
Sometimes referred to as Gbps. Nominally, a Gb is a transfer rate of
1,000,000,000 (10
9
) bits per second.
For Fibre Channel transceivers or FC loops the Gb transfer rates are:
• 1 Gb is a transmission rate of 1,062,500,000 bits per second.
• 2 Gb is a transmission rate of 2,125,000,000 bits per second.
