I have no experience with that raid card, most of our larger systems use 
external SAN storage, but I will say that, IMHO, is a very large 
raid-6.   we usually don't make single raid sets much large than 7-8 
drives, and for a very large storage system, will stripe multiple 
raid5/6 sets rather than have one huge one.
