Environmental Engineering (EE); Energy Efficiency measurement methodology and metrics for servers
|Publication Date:||1 March 2019|
The present document specifies a metric using the Server Efficiency Rating Tool (SERT™), test conditions and product family configuration for the assessment of energy efficiency of computer servers using reliable, accurate and reproducible measurement methods. The metric applies to general purpose computer servers with up to four processor sockets and with their own dedicated power supply.
NOTE 1: The term "socket" also applies to design in which processors are installed without sockets (e.g. soldered products).
The metric applies to a computer server model and to a computer server product family, including type and count of CPU, memory, storage, power supplies, cooling (e.g. fans) and any other add-on hardware expected to be present when deployed.
The present document defines:
• an energy efficiency metric to support procurement or market entry requirements;
• requirements for equipment to perform the measurements and analysis;
• requirements for the measurement process;
• requirements for the management of the metric calculation;
• operation or run rules to configure, execute, and monitor the testing;
• documentation and reporting requirements;
• a validation process for the metric using the Deployed Power Assessment.
The present document is not applicable to:
• fully fault tolerant servers;
• High Performance Computing (HPC) systems;
• hyper-converged servers;
• large scale servers;
• servers with integrated APA(s);
• networking equipment including network servers;
• server appliances;
• storage device including blade storage and storage servers.
NOTE 2: Products whose feature set and intended operation are not addressed by active mode testing parameters are excluded from this evaluation method. The above list shows products for which SERT™ efficiency evaluations are not appropriate.
The present document does not address home servers and small servers that fall under the scope of mandate M/545 [i.8].
