Thanks for the quick reply.

Can you tell me how the DPT interacts with the O/S?  If there
is a problem will the O/S notice (like a drive dies).  If a
disk should fail does the DPT automagically rebuild the RAID?

I was also looking at an external sub-system using the CMD
controllers in a fully-redundant config.  I have used this
before in a BSDI system with no problems, but wanted to see
if the DPT solution would perhaps be better, as well as less $$$.
