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 Fiber Channel, with a
hot-swappable electrical interface. Gigabit
interface converter ports can support a wide
range of physical media, from copper to optical
fiber, at lengths of up to hundreds of kilometers.
graphical user interface
A type of user interface that allows users to
interact with electronic devices using images
rather than text commands. Nexsan storage
units use a graphical user interface for system
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
computerized system while the system is
running. See also hot-swap.
hot-swap
To replace a failed or faulty component of a
computerized system while the system is
running. See also hot-plug.
I
I/O
Input/Output. The communication between an
information processing system (such as a
computer or a Nexsan storage system’s
RAID controller), and the outside world (either an
operator or another information processing
system). Inputs are the signals or data received
by the system, and outputs are the signals or
data sent from it.
IEC
The International Electrotechnical Commission.
Prepares and publishes international standards
for all electrical, electronic, and related
technologies.
interconnect service module
A module of the Nexsan E-Series storage units
that provides connectivity between all modules
in the chassis.
IP address
Internet Protocol address. A numerical label
assigned to each device (such as a computer,
printer, or Nexsan storage unit) on a computer
network that uses TCP/IP for communication.
iSCSI
Internet Small Computer System Interface. A
transport protocol that provides for the SCSI
protocol to be carried over a TCP/IP network.
ISM
See Interconnect Service Module.
L
LAN
See local area network.
LED
Light Emitting Diode. LEDs are used for indicator
lights on the front and back of Nexsan storage
units.
link module
A module of single-controller Nexsan E18/E18V
storage units that fits into a RAID controller slot
and provides connections to the mid-plane.
local area network
A computer network that links devices within a
small geographic area, such as a building or
group of adjacent buildings.
