I'll do that then post the results. I ran zcav on it (default settlings) on the disc array formatted XFS and its peak MB/s was around 85-90.  I am using kernel 2.6.17.7. mounting the disc array with noatime, nodiratime.

Thanks for your feedback.

Can you run bonnie++ version 1.03a on the machine and report the results
here?

It could be OK if you have the latest Linux driver for cciss, someone has
reported good results to this list with the latest, bleeding edge version of
Linux (2.6.17).
