vSphere 6.5 Configuration Maximums – Compare to Earlier Versions- Part 2
We’ve reviewed some of vSphere 6.5 configuration maximums in the previous post:
http://www.teimouri.net/vsphere-6-5-configuration-maximums/
And we’ll review and compare the rest of configuration maximums in this post.

vSphere 6.5 will support double ESXi host per vCenter.
2.5 x Powered-on virtual machine and 2 x registered virtual machine per vCenter server.
These are not all configuration maximums but I’ve mentioned all important items.
