Ah, I see! Thanks for making that clear. I have a spare VLB controller
which I am sure can be used as a tertinary/quad? device. I didn't know
this was possible; but thanks, now I can kick some serious butt with RAID.
Now where did I put it? Oh, I left it in England. :/

c0d0p0 will do fine. It makes logical sense to me now.
