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.
GB
Gigabyte. A unit of measurement defining either:
■ A storage or memory capacity of 1,073,741,824 (2
30
) bytes.
■ A data transfer rate.

GBIC
Gigabit Interface Converter.
See transceiver.
Gbps
Gigabits per second. A measurement of the rate at which the transfer of bits of data occurs.
Nominally, a Gb is a transfer rate of 1,000,000,000 (10
9
) bits per second.
See also Gb.
GBps
Gigabytes per second. A measurement of the rate at which the transfer of bytes of data occurs.
A GBps is a transfer rate of 1,000,000,000 (10
9
) bits per second.
See also GB.
Giga (G)
The notation to represent 10
9
or 1 billion (1,000,000,000).
