You must assign a license to a vSAN cluster before its evaluation period expires or its currently assigned license expires.
When you enable vSAN on a cluster, you can use vSAN in evaluation mode to explore its features. The evaluation period starts when vSAN is enabled, and expires after 60 days. To use vSAN, you must license the cluster before the evaluation period expires. Just like vSphere licenses, vSAN licenses have per CPU capacity. Some advanced features, such as all-flash configuration and stretched clusters, require a license that supports the feature.
- To view and manage vSAN licenses, you must have the privilege on the vCenter Server systems.
- Navigate to your vSAN cluster.
- Click the Configure tab.
- Right-click your vSAN cluster, and choose menu Assign License.
- Select an existing license and click OK.
