3.4. Installing vCenter Server in a Linked Mode Group

If your environment exceeds the recommended limits of a single vCenter Server instance, then vCenter Server 4.0 allows you to install multiple instances of vCenter Server and have those instances share inventory and configuration information for a centralized view of all the virtualized resources across the enterprise.

Table 3.1 shows the maximums for a single instance of vCenter Server. Using a Linked Mode group is necessary if you need to manage more than the number of ESX/ESXi hosts or virtual machines listed in Table 3.1.
