PowerOne uses a dynamic update approach that is centered around the cluster resource groups (CRG). This approach focuses on delivering a dynamic set of updates for CRGs, including the platform packages that are based on the VMware Validated Design (VVD) releases. As new component update packages (VVDs, drivers, firmware, and so on) are released, they are tested against PowerOne. Each package is a separate entity, which is dynamically brought together to conform to the needs of a CRG during an update. These updates can be applied to the vSphere Management Cluster or workload CRGs.
Updates are calculated and applied when a CRG is created. ESXi platform is installed with the necessary drivers and firmware to conform to the desired CRG configuration. This process is called baselining. Additionally, baselining occurs when compute sleds are added to a CRG. It brings the compute sled to a configuration that matches with the configuration of other compute sleds in the CRG. Lastly, updates are applied when a user chooses to update software on a CRG or vSphere Management Cluster. (This update process refers to the platform release version, for example, vSphere 6.7 Update 2, instead of individual releases that are calculated for the CRG.) Updates are applied to the vSphere Management Cluster in the same manner.
