Starting with version 4.7.100, VxRail supports vSAN 2-Node for small and Remote-Office Branch-Office (ROBO) deployments. This solution works best for environments that needs hyperconverged compute and storage with a minimal configuration. VxRail 2-Node consists of two VxRail E560 nodes and a vSAN Witness Appliance. It is recommended to deploy the Witness appliance in another site but in case of lacking another site it can be deployed in the same site as vSAN 2-Node.
There are some considerations and requirements that you need to have it in place before starting the VxRAIL 2-Node implementation.
