Your vCenter Single Sign-On domain might span multiple sites. When no load balancer is available, you
can manually repoint vCenter Server from a failed to a functional Platform Services Controller within the
same site. See Repoint vCenter Server to Another External Platform Services Controller.
Important Repointing vCenter Server between sites and domains is unsupported. If no functional
Platform Services Controller instance is available in the site, you must deploy or install a new
Platform Services Controller instance in this site. This new Platform Services Controller instance becomes
the replication partner of the existing Platform Services Controller instance.
Enhanced Linked Mode Overview
Enhanced Linked Mode connects multiple vCenter Server systems together by using one or more
Platform Services Controllers.
Enhanced Linked Mode lets you view and search across all linked vCenter Server systems and replicate
roles, permissions, licenses, policies, and tags.
When you install vCenter Server or deploy the vCenter Server Appliance with an external
Platform Services Controller, you must first install the Platform Services Controller. During installation of
the Platform Services Controller, you can select whether to create a vCenter Single Sign-On domain or
join an existing domain. You can select to join an existing vCenter Single Sign-On domain if you have
already installed or deployed a Platform Services Controller instance and have created a vCenter Single
Sign-On domain. When you join an existing vCenter Single Sign-On domain, the infrastructure data
between the existing Platform Services Controller and the new Platform Services Controller is replicated.
With Enhanced Linked Mode, you can connect not only vCenter Server systems running on Windows but
also many vCenter Server Appliances. You can also have an environment where multiple vCenter Server
systems and vCenter Server Appliances are linked together.
