Virtual disks / NICs

40 virtual disks / 8 virtual NICs

The maximum number of virtual disks includes the number of virtual NICs. If there are eight virtual NICs, only 32 virtual disks are supported. However, virtual disks are assigned a higher priority than virtual NICs. If you configure a virtual machine with 35 virtual disks and 8 virtual NICs, then 35 virtual disks and five virtual NICs are created.
