    • RAID-5/6 erasure coding

    While vSAN ROBO licenses are supported for VxRail vSAN 2-node clusters, these licenses are not orderable through VxRail. Witness Appliance license is not required but the host where the Witness resides needs the appropriate vSphere license. For more information, see the VMware vSAN Licensing guide.
