On a somewhat unrelated matter; I'll mention that I like 3ware RAID
controllers far more than the Dell ones. Neither are bug-free; but the 3ware
ones have far better user interfaces on their management tool. The Dell
management tools are a nightmare to get working on linux because there's so
many different RAID cards they've used over the years (and so many downloads
of different versions on their site) and it's really tough to know which one
you have unless you crack the case (not an option in a lights-out operation
like I do). The documentation on the Dell stuff is pretty poor; the 3ware
tools are pretty self-explanatory. I would go so far as to take out a PERC
card and buy a 3ware card to replace it, because it will save so much time
and hassle in management down the road. 

If you have 1000 servers all identical; then your situation is different
from mine and you can probably work with the Dell tools. Every one of my
boxen is unique; but the 3ware cards are consistent in their UI, and
consistently good.
