I will check those links out.. but do you have a quick summary you could give me? Do you see better performance out of multi proc VM's if they can utilize multi threads in the VM?
This depends on the actual application used.
With "SMP aware" applications like MSSQL, Oracle I'd use vSMP if necessary.
Multithread applications however can be run on single vCPU VMs as well and usually perform well.
My opinion: always start with a single vCPU VM
I don't see a reason why a DC would ever need vSMP.

You might check this thread out - a great discussion on cingle vs multiple vcpus - http://communities.vmware.com/thread/157849?tstart=0 and I agree woth oreeh start with one vcpu - you can always adde extras if needed -
