PowerOne uses a dynamic update approach based on the VMware Validated Design (VVD) releases. As new VVD versions are released, those updates along with associated firmware, drivers, and software components are tested against PowerOne. The resulting tested hypervisor, firmware, drivers, and software are assembled in a bundle that is tied to the VVD release. The bundles are made available to update both vSphere Management Cluster and CRGs. The bundles are applied intelligently when you choose to update a vSphere Management Cluster or CRG, or create a CRG in PowerOne Navigator. Updates to CRGs are dependent on the bundle that is applied to the vSphere Management cluster.
