The vSAN 2-node cluster must be connected to an external VCenter Server at the time of its deployment. The external VCenter Server can be customer-managed or a VCenter Server managing and running on another VxRail cluster.
VCenter Server version and deployment requirements are as follows:
- Version 6.7u1 or later is required for a 2-node cluster with direct-connect configuration.
- Version 6.7u3 or later is required for switch configurations.
- The VCenter Server must be deployed before the deployment of the 2-node cluster.
- VCenter Server cannot be deployed on the 2-node cluster.
