Ah, I was calling them XServe and XRaid It seems that Apple calls them 'XServe' and 'XServe Raid' These are two different boxes. The XServe takes max of 4 disks, raid 0,1 or unraided. and is a server. The XServe Raid, is a raid array - 'no server' hold up to 14 disks, does raid 0,1,5,10,50. Optimally, you would connect to two together. - Hope that's clearer. -- Peter -- Peter Clarke, Harrow Campus Computing Services, Technical Support.
