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.)

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...
