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 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.

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.

GUI Graphical User Interface. Software that displays the status of a storage system
and allows its user to control the storage system.
HBA Host Bus Adapter.
See also FCA .
host A computer that runs user applications and uses (or can potentially use) one or
more virtual disks created and presented by the controller pair.

host computer See host .
host link indicator The HSV Controller display that indicates the status of the storage system Fibre
Channel links.
host ports 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.
host-side ports See host ports .
hot-pluggable 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.
hub 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.
