To license an asset in vSphere, you must assign it a license that holds an appropriate product license key. You can use the license management functionality in the vSphere Web Client to license multiple assets at a time from a central place. Assets are vCenter Server systems, hosts, Virtual SAN clusters, and solutions.

In vSphere, you can assign one license to multiple assets of the same type if the license has enough capacity. You can assign a suite license to all components that belong to the suite product edition. For example, you can assign one vSphere license to multiple ESXi hosts, but you cannot assign two licenses to one host. If you have a vCloud Suite license, you can assign the license to ESXi hosts, vCloud Networking and Security, vCenter Site Recovery Manager, and so on.
