I do belive that buying 2 servers with 1 CPU each instead of 1 server
with 2 CPU pays better off.

We bought 4 singe-CPU-alphasservers(DS10) a few months ago, they
perform very very well as AFS-servers (250-400 clients), a 2-CPU
mashine would cost more than double the price, i do not belive it
would be better with 2 2CPU-servers instead. Especcially if you have a
lot of replicated data.

of course i dont know anything about pricing of your IBM-machine but i
assume that buying a 2 CPU-machine is at least 60-70% more expensive
that a 1 CPU-machine.
