Power Utilization Management Profile 6.1.2 Dynamic Power Utilization Dynamic power utilization mode enables a system to utilize proactive algorithms to adjust its power consumption. Such a mode is useful to balance power consumption with the system’s performance.
Power Utilization Management Profile The power utilization mode shall be represented by the PowerUtilizationMode, PowerUtilizationAlgorithm and PendingPowerUtilizationAlgorithm properties, and shall contain current and pending power algorithms of the impacted system respectively. The power utilization mode may also be managed through granular custom settings. The instance of DCIM_OEMPowerUtilizationCustomSettingData shall represent the custom settings of the power utilization mode.
Power Utilization Management Profile 7.4.1 Maximum Power Consumption Level If the CIM_PowerAllocationSettingData instance represents the maximum power consumption level for the managed system, then the referenced CIM_SettingsDefineCapabilities association’s ValueRange property shall have 2 (Maximums) value. The Limit property of the CIM_PowerAllocationSettingData instance shall represent the maximum power consumption level for the managed system in the units defined in the AllocationUnits property.
