GiB

A binary gigabyte, computed as 2^30
(1,073,741,824) bytes. See “GB”.

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.

GUI

See “graphical user interface”.

H

half duplex

See “duplex”.

host

A computer, server, or other device which
accesses the volumes in a Nexsan storage
system. The host can be connected to the
Nexsan storage system with a Fiber Channel
connection, an iSCSI connection, or a SAS
connection.

Host Identification Tool

One of six Nexsan Storage Tools. Allows users
to view the status and identifiers for local storage
interfaces (Fiber Channel, iSCSI, SAS).

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”.

hot spare

See “spare disk”.

HTTP

HyperText Transfer Protocol. A networking
protocol for distributed, collaborative hypermedia
information systems such as the World Wide
Web.

HTTPS

HyperText Transfer Protocol Secure. A
combination of HTTP and SSL used to provide
encrypted communication and secure
identification of a network web server.

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.

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.

IP Configuration Tool

One of six Nexsan Storage Tools. Allows users
to configure the IP address of a Nexsan storage
system on the local subnet.

iSCSI

Internet Small Computer System Interface. A
transport protocol that provides for the SCSI
protocol to be carried over a TCP/IP network.

J

jumbo frame

See “frame”.
