I switched our office from a LOUD HP DL160 1U machine and piggy backed it VMware on to our file server. You know how everyone is trying to save power and go green....
Installation was a breeze. It's on a modern quad core xeon server with 4gb ram (needs more), supermicro board, server 2008, and raid 10. It's like it's not even there. It's using around 175mb ram and .02% processor. Performance also seems to be better then the dual processor AMD with 4gb ram.
Our office consists of around 10 pc's and 3 servers (sql, exchange, fax).
