Thanks. Actually, we will be running VMWare ESX (which is already in use
elsewhere in the company). I checked and these features are already
included. My issue here is that our products are very memory intensive,
and my planning includes the possible retirement of standalone hardware
as a result of failure. I don't want to get a system that will run out
of steam this year.
