Each server running VMmark workload virtual machine was connected to the power meter for VMmark tests that included server power measurements. The power meter was connected to the physical client system running the Prime Client and configured as follows:
The VMmark benchmark is also configured to use the power meter. The Prime Client is configured to use the physical host’s serial port and PTD is set to True in the VMmark3.properties file, which also specifies the amp and voltage ranges.
PTD uses the following procedure to measure power:
The harness captures the power meter’s results into a single unified data stream once the required connections are made and the benchmark run is in progress. VMmark breaks this data into various sections (ramp-up, three 40-minute steady-state phases, and ramp-down).
Power consumption is reported as the total average watts consumed during the steady-state phase of the benchmark run that resulted in the median score. The total average watt consumption is the sum of the average watts reported by each power meter used in the run. The final VMmark Performance Per Kilowatt (PPKW) score is the VMmark 3.x score divided by the average power consumption in kilowatts.
