Create a LUN on it (1GB LUN for example) and then take a look at the usable size
We recently did some reorganizing of our Raid Groups and I have 2 600GB FC drives left over.  (CX4-960)  Since it seems a shame to let them sit there, I've figure may as well create a RAID group and let our ESX farm use it.  The strange thing is, if I create a RAID 1 or RAID 1/0 raid group, the usable storage reported by Navisphere is 1073GB.  I would expect it to be half that, at 536GB.    Does anybody have an idea as to why this is?  I just can't wrap my brain around it and want to be sure the Raid Group is acutally raid protected.  Thanks!
