vCenter Embedded Linked Mode for a vCSA with Embedded PSC

vCenter Embedded Linked Mode is enhanced linked mode support for vCenter Server Appliance with an embedded Platform Services Controller.

With vCenter Embedded Linked Mode, you can connect a vCenter Server Appliance with an embedded Platform Services Controller together to form a domain. vCenter Embedded Linked Mode is not supported for Windows vCenter Server installations. vCenter Embedded Linked Mode is supported starting with vSphere 6.5 Update 2 and suitable for most deployments.

Other features of vCenter Embedded Linked Mode include:

  • No external Platform Services Controller, providing a more simplified domain architecture than an external deployment with enhanced linked mode.
  • A simplified backup and restore process. See “File-Based Backup and Restore of vCenter Server Appliance” for more information.
  • A simplified HA process, removing the need for load balancers.
  • Up to 15 vCenter Server Appliances can be linked together using vCenter Embedded Linked Mode and displayed in a single inventory view.
  • For a vCenter High Availability (vCenter HA) cluster, three nodes are considered one logical vCenter Server node. See “vCenter Architecture Overview” in vSphere Availability for the vCenter HA architecture overview. A single vCenter Server standard license is needed for one vCenter HA cluster.

Note: Upgrading from vCenter 6.5 Update 2 to vCenter 6.7 GA is not supported.

  1. Hi thanks for this . An embedded PSC with ELM sounds like a obvious move to simplify VCHA designs . I did however stumble onto other informal blogs that state the multi site embedded PSCs will not be replication as they would if they were External . Any insights , grey area . Point 4 in this Blog . I would also be interested in comments on taking this towards AWS Hybrid later , as part of our road map .


      1. Thank you , but that is where i got stuck , there is only one NOTE listing 6.5U2 with embedded now capable of Linked mode . From what I can see , there is no diagram under recommended that shows . EG , Two physical sites , with VCSA and PSC in one VM , one SSO domain .

        This is the only reference to this model , unless I am missing something .

        Note: With vCenter Server 6.5 Update 2, you can deploy by using the GUI or CLI installer up to 15 vCenter Server Appliance instances in Embedded Linked Mode, and manage these instances with the vSphere Web Client or vSphere Client from any of the instances. “
