vCenter Enhanced Linked Mode allows you to log in to any single instance of vCenter Server Appliance or vCenter Server and view and manage the inventories of all the vCenter Server systems in the group.
- For vCenter Server Appliance with embedded Platform Services Controller deployments, you can join up to 15 nodes in one vSphere Single Sign-On domain.
- For vCenter Server with external Platform Services Controller installations, you can join up to 10 external Platform Services Controller and 15 vCenter Server systems in a single vSphere Single Sign-On domain.
You can create a vCenter Enhanced Linked Mode group during the deployment of vCenter Server Appliance or installation of vCenter Server.
After deployment, you can join a vCenter Enhanced Linked Mode group by moving, or repointing, a vCenter Server with an embedded Platform Services Controller from one vSphere domain to another exisitng domain. See Repoint vCenter Server with Embedded Platform Services Controller to Another vCenter Server with Embedded Platform Services Controller in a Different Domain for information on repointing an embedded vCenter Server node.
