What I tend to do is have a secondary controller (e.g. a 8006-2) with 2
drives as a simple mirror for the OS, and then use all the drives on the
9550 for the data partition. My latest system even has those 2 drives in
a hot-swap carrier accessible from the back (in addition to the 24 drives
accessible from the front).
But, yes, creating multiple arrays (or enabling auto-carving on the 3ware)
will work as well.
