Enhanced linked mode (ELM) enables you to manage all linked vCenter Server instances from a single vSphere Client connected to any one of the linked vCenter Server instances. The way that the vSphere Client visualizes the vSphere resources on a vCenter Server instance depends on the set of remote plug-ins installed on that instance. The topology of remote plug-ins is the overall configuration of plug-ins that determines how the vSphere Client interacts with the resources on different vCenter Server instances.
