License management is centralized. You can use the vSphere Client to manage all licenses that are available in the license inventory of a vCenter Server system or a Linked Mode group.

You can view the license keys available in the vCenter Server license inventory from the Licensing page in the vSphere Client.

After you obtain a license key, you can add it to the vCenter Server license inventory and assign the license key to assets.

After you obtain license keys, you can add them to the vCenter Server license inventory. You can add multiple license keys at the same time.

You can assign license keys to single or multiple assets, individually, or in batches.

You can export license information in a file that you can later open with third-party applications.

You can license an ESXi host that is connected to vCenter Server or if your vSphere Client is connected directly to the host. You can also query which features are licensed on a host or set a host to evaluation mode.

vCenter Server 5.0 requires a license server to manage licenses on ESX/ESXi 3.5. For ESX/ESXi 4.x and later hosts, vCenter Server 5.0 does not require a license server.
