Power Regulator for ProLiant settingsThe Settings tab of the Power Regulator for ProLiant section enables dynamically modifying processorfrequency and voltage levels based on operating conditions to provide power savings with minimal effecton performance. Processors that support this feature have predefined voltage and frequency states, knownas p-states. The software can dynamically switch the processor from one p-state to another. P-0 is thehighest frequency/voltage combination supported by the processor. Modifying the processor p-statebased on CPU utilization enables significant power savings with minimal performance degradation byreducing the voltage and frequency on the processor when the system is idle and increasing the voltageand frequency on the processor when needed.• Enable HP Dynamic Power Savings Mode sets the processor to dynamically set the power levelbased on usage.• Enable HP Static Low Power Mode sets the processor to minimum power.• HP Static High Performance Mode sets the processor to the highest supported processor state andforces it to stay in that highest state.• Enable OS Control Mode sets the processor to maximum power.Click Apply to save the desired setting. When changing the setting to or from Disabled, a server rebootis required to invoke the new setting. These settings cannot be changed while the server is in POST. If thesettings do not change after clicking the Apply button, the server might be booting. Exit any RBSUprogram you are running, allow POST to complete, and try the operation again.Using iLO 2 82
