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

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?

With all of the interrupt activity it seems counterintuitive that it
would be negligible in that the processor is incurring many extra

Interesting - Someone else mentioned the same thing
Hm... two points here. I, somehow, do not really believe that
software raid (gmirror for example) is as reliable as hardware.
I, deeply inside, believe that i might screw things very badly under some
heavy load and bad timing conditions. Can't explain it. it is religious
