Re: Accelerating Linux software raid

Hi,
Dan:

the md driver that allows it to take advantage of raid acceleration
hardware.  I/O processors like the Intel IOP333
(http://www.intel.com/design/iio/docs/iop333.htm) contain an xor
engine for raid5 and raid6 calculations, but currently the md driver
does not fully utilize these resources.

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.
