UCP rack-scale (RS) systems leverage the VMware vCenter Enhanced Link Mode to enable you to view and manage multisite VMware infrastructure and link multiple vCenter servers together for increased visibility.
After registering the UCP Advisor vCenter plugin and registering a UCP system on the management domain, repeat registration of the UCP Advisor vCenter plugin and UCP systems on each workload domain that you want to link. When you launch UCP Advisor, you will see the systems in the vCenter that you are logged into in the Registered Systems pane, and you will see all of the systems discovered in the linked workload domains in the Discovered Systems pane. You can view and perform all UCP Advisor operations in the inventory on the discovered systems in the same way that you do for the registered systems.
