Windows Server 2008 R2 x64 without Hyper-V Enabled

Windows Server 2008 Datacenter Edition supports up to 64 sockets and up to 256 logical processors


so 64 sockets, is what is limited by the Microsoft Datacenter Edition License.

Whether you can add that many to a VM, would depend on your version and license of VMware vSphere. (ESXi 5.5 - max 64 vCPU per VM, ESXi 6.0 - max 128 vCPU per VM)

Thanks Andrew, we are on 5.5. Should i be able to hot add the vCPU with datacentre? I edit the settings and they are greyed out

You should be able to hot add vCPU, but this option needs enabling first in Options, under VM settings.
