Servers are essential for data centers including their electricity use. It is important to be able to measure the energy efficiency (EE) of servers to keep track of the power consumption of data centers. Various so-called EE benchmarking software tools are used for standardizing the measurement. It is yet unknown if these tools are functionally equivalent, i.e. ranking and calibration equivalent. Here is presented a pioneering implementation for testing the functional equivalence of server EE measurement tools. For the first time, Benchmark of Server Energy Efficiency (BenchSEE) and Server Efficiency Rating Tool (SERT) are tentatively compared in terms of ranking and calibration equivalence. The preliminary suggestion is that the EE benchmarking tools BenchSEE and SERT are functionally interchangeable based on ranking and calibration equivalence. However, the research provides only tentative indications, limited by the small sample size.
