43 Dell HPC System for Manufacturing—System Architecture and Application Performance
5 System Power Requirements
Power requirements and power budgeting is an important consideration when installing any new
equipment. This section reports the power consumed by the three compute building block types for the
different applications described in Section 3. This data was obtained by using metered rack power
distribution units (PDU) and recording the actual power consumption of the building blocks during
benchmarking.
The recommended system profile for the Dell HPC System for Manufacturing is the Performance Profile.
This profile favors system performance over energy efficiency and typically yields an increase in
performance of a few percent as compared with the DAPC profile. All application power measurements
were performed using the Performance Profile. The application power graphs plot both the average and
peak power recorded while running each benchmark dataset. Some of the benchmark datasets complete
too quickly to provide accurate power measurements, so data for those benchmarks are not reported.
Figure 39 plots the average idle power consumption for the three compute building block types. Because
there is a significant difference in idle power consumption for the Performance and DAPC profiles, idle
power was recorded for both of these system profiles. The reported idle power is the average idle power
consumed by one server of each building block type. The value of the average idle power measurement is
shown at the top of each bar.

Figure 40 plots the power consumption of the three compute building block types when running HPL. The
peak power draw for HPL is likely to be the maximum power draw of the system under load. Most
