Nice!  I get an Opteron sometime next week with the 12 port card.  I went 
with the multilane connectors/backplane, so hopefully cabling things up 
should be tidy - each connector handles four drives.

Excellent.  I currently have a little script for these and the adaptecs 
that I drop in /usr/local/etc/periodic/daily.  I don't trust running the 
adaptec tool more than once a day.  Even that makes me a little nervous.

It's a devel box and all the production boxes are still 4.11.  Also I 
found out I can't use most of the modern cards - from what I can see both 
the Areca and 3Ware cards only are available in PCI-X/e and the box is old 
enough to not have either....

Additionally I have seen some hard lockups on a warm boot with the 3Ware 
card.  Disabling ACPI seems to make it happen less often, but 6.1 is 
giving me some jitters on this hardware combination.
