*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.
