A VMware vSAN 2-node cluster is a configuration that is implemented in environments where a minimal configuration is a key requirement.
VxRail v4.7.100 is the first release to support the vSAN 2-node cluster with direct-connect configuration.
Note: A minimum of four ports are required for both configurations.
This paper provides information for the planning of a vSAN 2-node cluster infrastructure on a VxRail platform. The paper focuses on the VxRail implementation of the vSAN 2-node cluster, including minimum requirements and recommendations.
