Temperature/Power
Select an entity on the ‘Datacenter Management’ page and then click the ‘Power/Temperature’ tab to view its power and temperature details.
Power and temperature data is plotted in the figures with the corresponding data granularities. CPU utilization data is plotted if the in-band OS information is specified for the given server. CPU sub-system and memory sub-system power is plotted if the server has such capabilities.
The ‘Highest Inlet Temperature’ is plotted in pink.
The ‘Lowest Inlet Temperature’ is plotted in green.
The ‘Average Inlet Temperature’ is plotted in brown.
The ‘Highest Power Consumption’ is plotted in red.
The ‘Lowest Power Consumption’ is plotted in brown.
The ‘IT Equipment Power’ is plotted in cyan (blue-green).
CPU utilization data will be shown only if the OS credential is specified for a device.
You can view the power/temperature values by moving your mouse over the data points in the curves.
By default, the power and temperature figures display the trending data of the recent hour. You can click the arrow buttons ‘<’ and ‘>’ to view the data in the previous and next time window, or switch to display the data in the time window of a different size by clicking the corresponding buttons.
You can save the measurement data in an Excel file so that the managers can analyze the data in a more convenient manner. To accomplish that, click the ‘Export data’ link on the top of the ‘Temperature/Power’ tab, choose the start and end time for data exporting, and then click OK.
The corresponding data granularity of a different time window size is different, and is explicitly shown in the figures. When the managed device is added, the real power reading may not be gotten from the managed device. At this time, Energy Manager uses its ‘Derated Power’ to report the IT equipment power. After the real power reading is gotten, Energy Manager will switch to the real power data as IT equipment power.
The ‘Power/Temperature’ tab also provides energy consumption metrics for the selected entity:
‘IT Equipment Energy’ gives the total energy consumption of all the IT devices.
‘Non IT Facility Energy’, calculated based on the ‘IT Equipment Energy’ and PUE (PUE=Total Facility Energy / IT Equipment Energy, could be specified in Settings page), estimates the energy consumption for non IT facility devices.
‘Total Facility Energy’ gives the total energy consumption from the IT devices and the non IT facility (e.g., the cooling system).
If the “Electricity Cost per kWh” and “Currency” are filled, the energy cost is automatically calculated. The energy cost of every row is: the value of “Electricity Cost per kWh” times the energy of the corresponding row. The cost value is rounded to two decimals.
