Dual power supply draw?

If a server has dual power supplies, and each is connected to a
different power feed, do the PSUs pull from both at the same time, or
do they pull 100% from one, and then if there's a failure switch to
the other?

Also, do you see any other problems with have each power supply on a
separate circuit?

I'm looking at both PE1950 and PE2950, and trying to spec out the power needs.
