Hmm - I don't remember seeing a machine spec. though I'm sure I remember
seeing a figure of 1800 quid for the server. Won't get you much in the
multi-CPU, multi-GB field, but definitely enough to buy two 1GHz Athlons
with 512M RAM + 40GB IDE drives, given current prices on everything. Just
don't fscking buy them from Scan (a number of you will know where I'm coming
from on this :-( ). Then you can have both servers running, users can pick
one from xdm and will soon learn to pick the one with lower load, and home
directories can be on one box, rsync'ed regularly with the other box. If the
box hosting the home directories goes down, it's a minor change to have it
use its local copy of the home directories. And in this scenario, you get a
total of 200Mbits bandwidth to the server(s) though given the load, as
somebody pointed out, 100Mbit is more than adequate anyway.
