vSphere provides a centralized license management system that you can use to manage licenses for ESXi hosts, vCenter Server systems, vSAN clusters, Supervisors, and solutions.

If your vSphere environment has several vCenter Server systems that are joined in Enhanced Linked Mode, the licensing inventory is replicated across all linked vCenter Server systems. This way, the licensing data for each asset and all available licenses are replicated across all linked vCenter Server systems. Each individual vCenter Server system contains a copy of that data and licenses for all linked vCenter Server systems.

Note: Licensing data is replicated across multiple linked vCenter Server systems on a 10-minute interval.

For example, suppose that your environment consists of eight vCenter Server systems that are joined in Enhanced Linked Mode, and every vCenter Server system has 10 hosts connected to it. You can manage the licensing for all eight vCenter Server systems and the 80 hosts that are connected to them through the vSphere Client.
