In the case, we could actually allocate more resources to the VM as the production hours for each region is different. Of course is not 1:1 comparison on the Cpu, we only provide to the system which really need it. actually, if you refer to my comment on this, it does describe that the VMs we run are serving multiple regiosn which contain, ASIA, EURO and NA in same ESX servers.

What surprised me is your statement: " have most VMs running with 4 Vcpu as the result of customer compare VM to Physical Servers to ensure the performance is sustainable or improve when they switch to VM. " Mate you must educate your customers, this is not a 1:1 scenario, 1 physical server wit x CPU=1 virtual machine with the same number of vCPU. Read more about how VMware co-schedules physical processors ... I find the limit OK so far.

Mate you must educate your customers, this is not a 1:1 scenario, 1 physical server wit x CPU=1 virtual machine with the same number of vCPU.

Not sure is the document error. Maybe you can help to clarify on this. Personally I have to say that different environment have different way to manage. We serve multiple timezone in single ESX servers, result as the busy hours for each VM will be different as it provide flexibility for my case to allocate more resources without impact the rest of the VM on same host. Just my 2 cents to share Hi Duncan, I am little confuse about the max number here, according to the document I downloaded from vmware, it show 128 Vcpu per servers. Not sure is the document error.

By the way the current max is 192 and not 128. And my guess is this will go up considering the fact that 8 vcpu's will be available in the next version. again keep in mind that using multiple vcpu vm's as standard will make scheduling much more difficult.
