HP Integrated Lights-Out 2 User Guide

Processor StatesSelecting the Processor States tab displays the Power Regulator Data page. The Power Regulator Datapage enables you to view p-state data reported by the Power Regulator feature of the server. Only userswith Configure iLO 2 Settings privilege can view Power Regulator data. An iLO 2 license is required toview Power Regulator data.The Power Regulator Data page displays the current p-state and a running average of the percentage oftime each logical processor has spent in each p-state over the previous 24-hours. The data is collectedstarting from host powerup once a second, and refreshed for display once every 5 minutes. The data isdisplayed using a bar graph, with the total bar length representing 100% of the time covered by thedata. A portion of the bar is colored differently for each p-state the processor was in, with each coloredportion scaled to represent the percentage of the total time the processor spent in that p-state.Pausing the mouse over the bar graph will cause a tool tip to be displayed that will indicate the numericpercentage that portion of the bar represents.The ROM will read the current status of each logical processor. The status register in Intel®-basedplatforms reflects the current operating frequency and voltage. Because of multiple-processordependencies, the status might or might not reflect an absolute p-state. The frequency might be at one p-state and the voltage at a higher p-state. The ROM will update the p-state count of the p-state for thecurrent frequency and not the current voltage.One data graph will be displayed for each processor/core. Data graphs for multiple threads on aprocessor or core that supports Hyper-Threading are not displayed.Power Meter ReadingsThe Power Meter Readings page enables you to view the power readings from the server displaying aPower Data Graph and averaged information.The Power Data Graph shows the power usage of the server over the previous 24 hours. iLO 2 collectspower usage information from the server every 5 minutes. For each 5-minute time period, the peak andaverage power usage is stored in a circular buffer. These two values are displayed in the form of a bargraph, with the average value in blue and the peak value in red. This data is reset whenever either theserver or iLO 2 is reset.• Present Power Reading value displays the current power reading from the server.• Average Power Reading displays the average of the power readings from the server over the last 24-hour period. If the server has not been running for 24 hours, the value will be the average of all thereadings since the server was booted.Using iLO 2 83
