With vSphere 6.0, all additional vCenter Server services, such as the vSphere Web Client, Inventory Service, vSphere Auto Deploy, Syslog Collector, vSphere ESXi Dump Collector, and so on, are installed on the same server as the vCenter Server service. During an upgrade, should any of these services be installed on a different host server, the upgrade will pull the configuration from these services and apply it to the service installed on the vCenter Server 6.0 instance.

There is no longer a way to deploy these components on different servers from the vCenter Server. The exception to this is vSphere Update Manager, which, at the time of writing, remains a separate installation that can, and generally should, be installed on a different server. Where the vCenter Server Appliance has been deployed, the vSphere Update Manager server must still be installed on a separate Windows server and registered with the vCenter Server Appliance. Currently, vSphere Update Manager is a Windows-only service.
