A Linked Mode group allows you to log in to any single instance of vCenter Server and view and manage the inventories of all the vCenter Server systems in the group.

You can join multiple vCenter Server systems to form a Linked Mode group. You can configure a Linked Mode group during vCenter Server installation or after vCenter Server is installed.

To join a vCenter Server group, you enter the fully qualified domain name (or IP address) of a remote machine on which vCenter Server is running. The remote machine can be any vCenter Server instance that is or will become a member of the Linked Mode group.

You must also provide the Lightweight Directory Access Protocol (LDAP) port number of the remote vCenter Server instance.

vCenter Server instances in a group replicate shared global data to the LDAP directory. The global data includes the following information for each vCenter Server instance:

Connection information (IP and ports)

Certificates

Licensing information

User roles

Note

vCenter Server 4.0, vCenter Server 4.0 Update 1, and vCenter Server 4.1 can be joined in the same Linked Mode group, but both vSphere Client 4.0 and vSphere 4.1 are required to log in to the Linked Mode group.
