I was reviewing the Configuration Maximums document for vSphere 6.0 which was released today and comparing it to vSphere 5.5 to see what has changed and noticed that the maximum Virtual CPU support (vCPU) was reduced by half from 4,096 in vSphere 5.5 to 2,048 in vSphere 6.0. Not sure if this is a typo or if this is actually the case, it seems odd though as the support for the number of physical CPUs in a host has increased from 320 in vSphere 5.5 to 480 in vSphere 6.0. Also note the number of VM’s per host has doubled from 512 in vSphere 5.5 to 1,024 in vSphere 6.0 so the reduction in the max vCPUs seems strange.
vSphere 5.5 Configuration Maximums:
vSphere 6.0 Configuration Maximums:
UPDATE: VMware must of read my post and fixed their error in the vSphere 6.0 documentation, the supported vCPUs in vSphere 6.0 remains the same as vSphere 5.5 at 4,096.
