When you prepare your cluster for vSAN, review the requirements of the vSAN 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 vSAN expires, you can continue to use the current configuration of vSAN 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 vSAN 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 vSAN license across the cluster when adding and removing hosts to the cluster.
vSAN licenses have per CPU capacity. When you assign a vSAN license to a cluster, the amount of license capacity used is equal to the total number of CPUs on the hosts that participate in the cluster.
