Hi.
Interesting - Someone else mentioned the same thing. The amr(4)
manpage doesn't seem to be updated to mention the latest cards
though. I did notice the driver hasn't been really updated in a
while either. Wouldn't this cause a problem with identifying the
newer cards?

One thing I would like to see is a list of favoured non-raid multiport cards
that are not dumb. We have a server running a rocket RAID controller
(largely to get 8 ports of SATA). It doesn't do hot swap, it doesn't do
SMART and I'm beginning to believe it might occasionally corrupt sectors

Jaime, can you expand a bit about what sort-of motherboard you
installed the 1261ML in? I've yet to find any mainstream motherboards
which have a PCIe x8 slot. Most have x1, some have x4, and many
have x16. I've seen one Supermicro board which has a x8 slot but
is only wired for x4 (has 4

With all of the interrupt activity it seems counterintuitive that it
would be negligible in that the processor is incurring many extra
cache faults to service the controller.

Hardware RAID1 buys you nothing in perfomance and reliability
for a prolonged headache with drivers, bios insanity and
monitoring+control tools.
Intel does seem to have a few hardware-based RAID controllers here:

I don't see any driver or support
