VCenter Server

  • 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.
