What is the difference between LUN and RAID?
Answer Posted / mayur gandhi
A logical unit number (LUN) can refer to an entire physical disk, or a subset of a larger physical disk or disk volume. The physical disk or disk volume could be an entire single disk drive, a partition (subset) of a single disk drive, or a disk volume from a redundant array of independent disks (RAID) controller comprising multiple disk drives aggregated together for larger capacity and redundancy. LUNs are an important factor in managing block storage arrays shared over a SAN. A LUN represents a logical abstraction or, if you prefer, virtualization layer between the physical disk device/volume and the applications
