Greg has a point. However, for us, we would rather have more
nodes than UPSes. We problems that UPSes might not solve
(like maintenance guys who flick power switches on the main
panel or people who unplug power cords - UPSes don't help
too much in those cases :)
So far with a total of somewhere near 700 nodes in various
cluster, for about 2+ years, we haven't had any problems.
