When you prepare your cluster for Virtual SAN, review the requirements of the Virtual SAN license.
Make sure that you obtained a valid license for full host configuration control in the cluster. The license should be different from the one that you used for evaluation purposes.
After the license or the evaluation period of a Virtual SAN expires, you can continue to use the current configuration of Virtual SAN resources. However, you cannot add capacity to a disk group or create disk groups.
If the cluster consists of all-flash disk groups, verify that the all-flash feature is available under your license.
If the Virtual SAN cluster uses advanced features such as deduplication and compression or stretched cluster, verify that the feature is available under your license.
Consider the CPU capacity of the Virtual SAN license across the cluster when adding and removing hosts to the cluster.
Virtual SAN licenses have per CPU capacity. When you assign a Virtual SAN license to a cluster, the amount of license capacity that is used equals the total number of CPUs on the hosts that participate in the cluster.
For more information about vSAN licensing editions and potential licensing scenarios, see the VMware Virtual SAN 6.2 Licensing Guide.
