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 data transfer rate.
•
A storage or memory capacity of 1,073,741,824 (2
30
) bytes.

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
) bytes per
second.
