a single server (implying 1 gb nic?) might have trouble with the tftp part,
but I don't see why you couldn't scale up by splitting the tftp part
off to multiple servers.  I'd expect a single DHCP (no TFTP) would be 
plenty in all cases.  100 tftp clients per server would probably
be pretty safe.

I personally like the idea of putting one admin server in each rack.
they don't have to be fancy servers, by any means.

do you mean you'd expect load problems even with a single sever 
dedicated only to dhcp?

why would you want logs local?
