Hi,
Dan:

does that mean offloading RAID to the IOP board or simply using the
XOR engine in the IOP ?
if you have some benchmarks which shows that under certain workload md
is not IOlimited(due to excessive XOR computation) and then concluded
that offloading XOR is a gud idea , then it must be :) ...
I was going thru IOP manual myself and saw that they have a raid6
accelaretor too :)
Let me know.
