The vCenter instance that is bundled with the VxRail software and deployed during the initial build process is compatible with the VxRail/vSphere software stack.
With VxRail 7.0.130 and later, VxRail Manager no longer validates whether a customer-supplied vCenter Server is compatible with the VxRail/vSphere software stack. See the VxRail and external vCenter interoperability matrix to confirm that your customer-supplied vCenter Server is running the minimum compatible version before commencing initial build.
