no, I really meant to put one admin server (1u is fine) in each rack.
I'd already have a Gb switch and possibly a high-speed interconnect
leaf in the rack if possible. a modular approach like this cuts
down on cabling and out-of-rack traffic.

why would you run tftp from xinetd? generally I don't see the point to
inetd anymore - it was a cool hack from days when you wanted lots of
daemons reachable, but didn't want them in memory. I usually remove it.

if your logs are enough to interfere with other traffic, something's wrong.
but perhaps you don't look at your logs as much as I do (which is why
I want them coalesced.)
