Were these deployed on bare metal or as virtual machines?  If Virtual 
were they on vmware?

Can anyone else chime in on their experience with these platforms in a 
vmware environment?  Are there any special network card / controller 
card settings that have worked best?

Can anyone speak to how well a virtual machine will perform when being 
given 1 socket 1 core, vs. 1 socket 2 cores vs 2 sockets 1 core?
