*LOLOL* At first I was guilty of the one things I am always getting on the
other guys for-thinking too literally. I was going to say there is no room in
the rack. Of course, the server would not have to even be on the same
side of the room. :)

dhcp is not the problem (it is only critical during kickstart and for laptops moved
in on a temporary basis. tftp was a problem because of xinetd. We bought 1024
dual opt nodes in 16 racks. When we received the first 6 racks we triggered them
all for install-it did not work as expected.

We have huge data sets, huge scratch data, huge library data (travel time sets)
and I worry about network traffic.
