Cluster Requirements for vSAN

Verify that a host cluster meets the requirements for enabling vSAN.

• All capacity devices, drivers, and firmware versions in your vSAN configuration must be certified and listed in the vSAN section of the VMware Compatibility Guide.

• A vSAN cluster must contain a minimum of three hosts that contribute capacity to the cluster. For information about the considerations for a three-host cluster, see Design Considerations for a vSAN Cluster.
• A host that resides in a vSAN cluster must not participate in other clusters.
