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]].<ref name="techopedia">{{cite web

A LUN may be used with any device which supports read/write operations, such as a [[tape drive]], but is most often used to refer to a [[logical disk]] as created on a [[Storage area network|SAN]].  Though not technically correct, the term "LUN" is often also used to refer to the [[logical disk]] itself.<ref>{{cite book|author=James Long|url=https://books.google.com/books?id=zEFrqPrcZI8C&pg=PA111|title=Storage Networking Protocol Fundamentals|publisher=[[Cisco Press]]|year=2006|isbn=9781587051609|page=111}}</ref>
