Thanks for the tip!  This looks like a better solution than the Adaptec 
card, since I can get 8 and 12 drive versions.

Do you know if it's possible to add drives to an existing array?  I'd 
like to be able to start with a 4 or 5 disk RAID5 array, with the 
ability to add another couple drives when the marketing dept. fills up 
the space with cruft. :)

I'm crawling through their online docs, but there's nothing like having 
been through an actual install.
