Hi kedar,
Whatput mea bitof confusionis containedat the endof the second pageof this document:http://www.vmware.com/files/pdf/products/vsphere/VMware-vSphere-Essentials-Kits-DataSheet.pdf.
At the end of the first column: "VMware vSphere Virtual Symmetric Multiprocessing enables the use of ultrapowerful virtual machines that have up to four virtual CPUs"
Perhaps thisdocumentis out of date?
Many Thanks
Andrea.
