Starting with vSphere 6.5 Update 2, vCenter supports enhanced linked mode (ELM) with an embedded platform services controller (previous versions required external PSCs to enable ELM). This will definitely reduce the complexity of multi site VMware Infrastructure. Please Note: The recommendation from vSphere 6.5 U2 and vSphere 6.7 onwards, is to use Embedded PSCs. The caveat here is there is not a currently supported method to upgrade or migrate from external PSC deployment to an embedded PSC deployment.
Benefits of using of vCenter Embedded Linked Mode include:
- No load balancer required for high availability and fully supports native vCenter Server High Availability.
- Allows for 15 deployments in a vSphere Single Sign-On Domain.
- A simplified backup and restore process.
- Supports vSphere scale maximums.
- For a vCenter High Availability (vCenter HA) cluster, three nodes are considered one logical vCenter Server node. This represents ten times the vCenter HA clusters in a vCenter Embedded Linked Mode for a total of 30 VMs.
