There's an interesting thread about the AMR RAID controller used in

Thanks for your note. Turns out I have more than one Dell system with
aac controllers in them :-)
They seem to be OK, although I like the AMR's a little better. I had to update
the RAID BIOS on the PE 2650 before auto-rebuild of a broken mirror would work
right using the aac controller.
(It's either rackrounted Dells or HP 370/380 Proliants for me, depending upon
the specific client in question.)
One happens to be a PE 1750 with the PERC 3/Di in it running RAID1. It
is lightly loaded but is sufficient for that server's needs, but is
running FreeBSD 4.11 on it.
Is there a way to backport this diskinfo utility to 4.x or 5.x? Looks
most useful! On my 6.0 box with a PERC 3/Si card (aac driver too) it
is showing seek times slower than yours but transfer rates faster.
diskinfo runs on 5.x, at least. I'm not sure about 4.x; I think some of the
underlying infrastructure which smarttools also depends upon wasn't available
until 5.x...
