you are jumping to conclusions too quickly - while the 8k is not the
worlds fastest raid card available it is really not (that) bad at all.
we have plenty of x3650 in production and last time I tested I was
easily able to get >>2000tps even on an untuned postgresql install and
with fwer disks.
So I really think you are looking at another problem here (be it
defective hardware or a driver/OS level issue).
is your SLES10 install updated to the latest patch levels available and
are you running the recommended driver version for that version of SLES?
