I assume you mean the SRC/P, which is an OEM DPT card.  Provided you get
the latest drivers it seems to be solid and fast.  It does seem like there
would be termination issues with cascading the internal backplanes to run
more than 12 disks internally (I still have mine in my U30, haven't moved
it to the E450 yet).  I'd love more info but people with practical
experience with this card seem to be few and far between.

I run 24 disks, 8 per chain.  It would be ideal for me to use 16 internal
bays on an E450 for 2 chains and run the third chain externally.
