Comparison of VMware vCenter Configuration Maximums
Comparing VMware vCenter Configuration Maximums:
In continuation with my previous blog “VMware Virtual Machine and ESXi Maximums” lets take a look at the comparison of VMware vCenter Maximum supported configurations, where I have included the most recent versions of vCenter Server, 5.5, 6.0 and 6.5. vCenter Configuration Maximums values are fully tested and validated by VMware.
VMware vCenter Configuration Maximums:
This table shows the maximum supported values of vCenter Server scalability, User interface, vMotion, Content Library, Host Profile, Storage DRS and Platform Services Controller.
