F
FC port
See Fibre Channel port.
FCC
The Federal Communications Commission;
the United States federal agency that regulates
electromagnetic emissions.
Fibre Channel
A gigabit (Gb) speed network technology
primarily used for storage networking and the
current standard connection type for storage
area networks (SANs). Despite its name, Fibre
Channel signaling can run on both twisted-pair
copper wire and fibre-optic cables.
Fibre Channel port
Any entity that actively communicates over a
Fibre Channel network. Usually implemented
in a device such as disk storage or a Fibre
Channel switch. Depending on the system, the
Fibre Channel ports on Nexsan Storage Sys-
tems can support 2Gb/s, 4Gb/s, 8Gb/s,
16Gb/s, or 32GB/s connections.
Fibre Channel switch
A network switch compatible with the Fibre
Channel protocol. Enables the creation of a
Fibre Channel network, which is currently the
core component of most storage area net-
works (SANs).
FRU (Field Replaceable Unit)
A module within a Nexsan Storage System or
Nexsan Storage Expansion that can be
replaced on site. Consult Nexsan Support for
details.
G
Gb
Gigabit. Approximately one billion
(1,000,000,000) bits.
GB
Gigabyte. Approximately one billion
(1,000,000,000) bytes. Used to describe the
storage capacity of hard disk drives. A giga-
byte is usually computed as 109
(1,000,000,000) bytes, but can also be com-
puted as 230 (1,073,741,824) bytes (often
called a “binary gigabyte” and abbreviated
GiB).
Gb/s
Gigabits (Gb) per second. Used to describe
the speed of network data transmission.
GB/s
Gigabytes (GB) per second. Used to describe
the speed of network data transmission. 1
GB/s is eight times faster than 1Gb/s.
gigabit interface converter
A standard for transceivers, commonly used
with Gigabit (Gb) Ethernet and Fibre Channel,
with a hot-swappable electrical interface. Gig-
abit interface converter ports can support a
wide range of physical media, from copper to
optical fibre, at lengths of up to hundreds of kilo-
meters.
graphical user interface
A type of user interface that enables users to
interact with electronic devices using images
rather than text commands. Nexsan Storage
Systems use a graphical user interface for sys-
tem configuration.
grounding bracelet
See anti-static wrist strap.
GUI
See graphical user interface.
H
hot-plug
To insert a new piece of hardware into a com-
puterized system while the system is running.
See also hot-swap.
