Starting with VxRail 4.7.100, VMware vSAN 2-node cluster direct connect is supported using VxRail E-Series platforms. Switch configuration is supported in v4.7.410 or later. A VMware vSAN 2-node cluster is a minimal configuration consisting of two vSAN data nodes and a Witness virtual appliance.
vSAN 2-node cluster can easily be deployed anywhere. Many vSAN 2-node clusters can be managed by a single vCenter instance. This minimal configuration continues to provide the same functional benefits of vSphere and vSAN. It enables an efficient centralized management with reduced hardware and software costs, while meeting the needs of environments with limited space, budget and/or IT personnel constraints.
