that's "1 Server + VMware cost 10K". you need to learn how to read.
a 2.0 quad core + 8gb ram + SAN easily runs 10 VMs serving 50-100 local users and a lots of web visitors. maybe not 10 database servers but something like 2 domain controllers 1 exchange server 2 database servers 2 web servers 1 file server 1 backup server 1 other server hosting office communicator, share point stuff
It really works, I can send you a screenshot. I've been using VMWare product since 2003 (ESX, GSX, VMServer & WorkStation). If you configure things correctlly it works perfectly + when the load is to high to handle VMWare can automatically move a live server to another w/out shutdown nor loss of tiny bit of information. This is truely amazing product.
