I don't know all of the details--Erik Paulson may jump in here. But I do 
know that our central manager is a RedHat 7.2 computer, one CPU that is > 
2GHz, about 1G of main memory and 2G of swap space.

We run both the collector and the negotiator on one machine. We do not run 
a condor_startd on the machine, so we do not allow jobs on the central manager.

Our checkpoint servers seem to change periodically. At the moment, we have 
three active checkpoint servers. I think that they each have 100-400G of 
space on them. They are set up as RAID, I think, but again I'm not sure 
which kind. Maybe Erik can jump in on this one too.

For most of our machines, we randomly select which checkpoint server to use:

CKPT_SERVER_HOST = $RANDOM_CHOICE(choice1, choice2)
