Thanks for the encouraging feedback. It appears that the driver in FC4
is a bit old (and doesn't seem to correspond to a 3Ware release). Are
you running SMP?
Both - running an Athlon64, 32bit PCI slot, 2 mirrored drives and
a quad
opteron, pci-x, 4 raid 0 drives.

I plan to compile the latest driver tomorrow...
The driver in the FC4 kernel is
2.26.02.002 (grep -i
version /lib/modules/2.6.11-1.1369_FC4/kernel/drivers/scsi/3w-9xxx.ko)
while the driver that amcc has is 2.26.03.015fw (grep TW_DRIVER_VERSION
3w-9xxx.c) Its not that great a difference but it might be worth it for you.
Don't forget to check the firmware upgrades as well.

Interesting. Actually, my IO needs are not *that* heavy, but I first
encountered the problem when trying to restore a bunch of backups from
my previous machine.
High is relative... Sometimes a simple script can create a ton
of IO for just
a few seconds and that can be enough. :-)
