Logical unit number, the Glossary
In computer storage, a logical unit number, or LUN, is a number used to identify a logical unit, which is a device addressed by the SCSI protocol or by Storage Area Network protocols that encapsulate SCSI, such as Fibre Channel or iSCSI.[1]

Computer data storage
Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data.
See Logical unit number and Computer data storage
Concatenation
In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end.
See Logical unit number and Concatenation
Disk partitioning
Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately.
See Logical unit number and Disk partitioning
Fibre Channel
Fibre Channel (FC) is a high-speed data transfer protocol providing in-order, lossless delivery of raw block data.
See Logical unit number and Fibre Channel
Host adapter
In computer hardware a host controller, host adapter or host bus adapter (HBA) connects a computer system bus which acts as the host system to other network and storage devices. Logical unit number and host adapter are SCSI.

HP-UX
HP-UX (from "Hewlett Packard Unix") is Hewlett Packard Enterprise's proprietary implementation of the Unix operating system, based on Unix System V (initially System III) and first released in 1984.
See Logical unit number and HP-UX
IBM AIX
AIX (Advanced Interactive eXecutive, pronounced) is a series of proprietary Unix operating systems developed and sold by IBM for several of its computer platforms.
See Logical unit number and IBM AIX
ISCSI
Internet Small Computer Systems Interface or iSCSI is an Internet Protocol-based storage networking standard for linking data storage facilities. Logical unit number and iSCSI are SCSI.
See Logical unit number and ISCSI
Logical disk
A logical disk, logical volume or virtual disk (VD or vdisk for short) is a virtual device that provides an area of usable storage capacity on one or more physical disk drive(s) in a computer system.
See Logical unit number and Logical disk
Logical Unit Number masking
Logical Unit Number Masking or LUN masking is an authorization process that makes a Logical Unit Number available to some hosts and unavailable to other hosts.
See Logical unit number and Logical Unit Number masking
NCR Voyix
NCR Voyix Corporation, previously known as NCR Corporation and National Cash Register, is an American software, consulting and technology company providing several professional services and electronic products.
See Logical unit number and NCR Voyix
Operating system
An operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs.
See Logical unit number and Operating system
Oracle Solaris
Solaris is a proprietary Unix operating system originally developed by Sun Microsystems.
See Logical unit number and Oracle Solaris
Programming language
A programming language is a system of notation for writing computer programs.
See Logical unit number and Programming language
RAID
RAID ("redundant array of inexpensive disks" or "redundant array of independent disks") is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
See Logical unit number and RAID
SCSI
Small Computer System Interface (SCSI) is a set of standards for physically connecting and transferring data between computers and peripheral devices, best known for its use with storage devices such as hard disk drives.
See Logical unit number and SCSI
SCSI CDB
In SCSI standards for transferring data between computers and peripheral devices, often computer storage, commands are sent in a Command Descriptor Block (CDB). Logical unit number and SCSI CDB are SCSI.
See Logical unit number and SCSI CDB
Storage area network
A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage.
See Logical unit number and Storage area network
Tape drive
A tape drive is a data storage device that reads and writes data on a magnetic tape.
See Logical unit number and Tape drive
Unix
Unix (trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
