Basic concepts of LUN, RAID, volume...

807557Nov 14 2006 — edited Nov 14 2006

Could somebody please describe how the concepts of LUN, RAID, and volume relate to each other? Individually, I know in basic terms what LUN and RAID are, but how do they relate to each other?

If you have 20 disks comprising your total storage, what confuses me is that you can divide it into several different RAID groups, but that you can also divide it into several different LUNs as well.

So I don't see how both concepts relate to each other. Are they parallel, unrelated concepts, or is there something I'm missing here?

Thanks.
