I
IP address
A unique 32-bit value that identifies network hosts using TCP/IP. An IP address, or block of
addresses, is assigned upon application to organizations responsible for that function. No two
network hosts can be assigned the same IP address. Each address consists of a network
number, optional subnetwork number and host number, written as four numbers separated by
periods. Each number can be 0 to 255.
L
Local Area Network (LAN)
A group of computers and other devices, within a specific location (typically within a building
or floor of a building), connected by a communications link that enables any device to interact
with any other on the network. LANs commonly include microcomputers and shared
resources such as laser printers and storage devices.
Logical drive
A logical grouping of one or more physical drives on a system, commonly referred to as a
RAID set.
Logical Unit Number (LUN)
A logical unit number (LUN) is a unique identifier used on a SCSI bus that enables it to
differentiate between up to eight separate devices (each of which is a logical unit). Each LUN
is a unique number that identifies a specific unit of storage, which may be an end user, a file,
or an application program.
Logical Volume
The basic unit of logical storage for a file system on the HP NAS VA.
LUN
See logical unit number.
M

order to participate in a domain.
Media Access Control (MAC) address

and lists of block addresses at which each file's data is stored.
Mount
To make a portion of a file system on a remote computer accessible to a local (client)
computer. The term is most commonly used with UNIX-based computers.
