Enhanced Linked Mode allows for multiple vCenter Servers to be connected together to provide a single point of management. Enhanced Linked Mode enables the ability to view, search, and manage multiple vCenter Servers, and provides the replication of roles, permissions, licenses, and policies between vCenter Servers. This simplifies the management of large environments, with multiple vCenter Servers deployed in the same site or across multiple sites. vCenter 6.x supports linking vCenter Servers that have been deployed as VCSAs and as Windows Servers with external PSCs. Recall from earlier in this chapter that Enhanced Linked Mode is only supported between VCSAs when you are using embedded PSCs.
