You can install vCenter Server and the Platform Services Controller on different virtual machines or physical servers.

You can separate the Platform Services Controller and vCenter Server and have them installed on different virtual machines or physical servers. First install the Platform Services Controller, then install vCenter Server and the vCenter Server components on another virtual or physical machine, and connect vCenter Server to the Platform Services Controller. You can connect many vCenter Server instances to one Platform Services Controller.

Important

Concurrent installations of vCenter Server instances and Platform Services Controllers are not supported. You must install the Platform Services Controllers and vCenter Server instances in a sequence.

vCenter Server with an External Platform Services Controller
The Platform Services Controller is installed on one virtual machine or physical server and the vCenter Server instances registered with the Platform Services Controller are installed on other virtual machines or physical servers.

After you deploy vCenter Server with an embedded Platform Services Controller, you can reconfigure your topology and switch to vCenter Server with an external Platform Services Controller. This is a one-way process after which you cannot switch back to vCenter Server with an embedded Platform Services Controller. You can repoint the vCenter Server instance only to an external Platform Services Controller that is configured to replicate the infrastructure data within the same domain.

Important

Before installing vCenter Server with an external Platform Services Controller, synchronize the clocks on the vSphere network. Time skew on the virtual machines or physical servers on which you install the Platform Services Controller and vCenter Server might cause deployment failure. For instructions about synchronizing the clocks on your vSphere network, see Synchronizing Clocks on the vSphere Network.
