2 Node minimum
VxRail 4.7.100 introduced support for 2-node clusters:
- The deployment is limited to VxRail Series E-Series nodes.
- Only 1GbE and 10GbE are supported. Inter-cluster VxRail traffic utilizes a pair of network cables linke between the physical nodes.
- A customer-supplied external vCenter is required that does not reside on the 2-node cluster.
- A Witness VM that monitors the health of the 2-node cluster is required and does not reside on the 2-node cluster.

2-node clusters are not supported when using the VxRail G410 appliance.
