Information AboutLun |
|
The term has become common in Storage Area Network s (SAN) and other Enterprise Storage fields. Today, LUNs are normally not entire disk drives but rather Virtual Partitions (or ''volumes'') of a RAID Set . NOMENCLATURE In SCSI, LUNs are addressed in conjunction with the ''controller ID'' of the Host Bus Adapter , the ''target ID'' of the storage array, and an optional (and no longer common) ''slice ID''. In the UNIX family of Operating System s, these IDs are often combined into a single "word". For example, "c1t2d3s4" would refer to controller 1, target 2, disk 3, slice 4. Only Sun 's Solaris operating system continues to use LUN slices, and IBM 's AIX has abandoned the "ctd" nomenclature in favor of more familiar names. SEE ALSO EXTERNAL LINKS |
