Introduction

In order to standardize the energy efficiency measurement testing work of liquid-cooled server systems, according to JJF 1071-2010 "National Metrology School This specification is formulated in accordance with the requirements of "Quasi Specification Writing Rules": This specification is released for the first time: Liquid-cooled server energy efficiency Measurement test specifications

1 Scope

This specification applies to the capabilities of independently powered and non-independently powered liquid-cooled server systems using the Linux operating system: The measurement of efficiency parameters can be used to analyze the energy efficiency status of liquid-cooled servers and provide information for the design, manufacturing, operation and maintenance, and modification of liquid-cooled servers: It can be used as a reference for rating the energy efficiency level of liquid-cooled servers:

2 cited documents

This specification references the following documents: JJF 1059:1-2012 Evaluation and expression of measurement uncertainty For dated referenced documents, only the dated version applies to this specification; for undated referenced documents, only the dated version applies: The latest version (including all modification orders) applies to this specification:

3 Terminology and units of measurement

The following terms and definitions apply to this specification: 3:1 Liquidcoolingsystem liquidcoolingsystem A device or system that uses liquid to remove heat from a heating device: Note: Liquid cooling systems are suitable for application scenarios where performance indicators such as computing power, energy efficiency, and deployment density need to be improved: 3:2 Liquidcoolingserver liquidcoolingserver Server products that use liquid hot and cold exchange to take away the heat of server heating devices as the main heat dissipation method: When the liquid-cooled server system operates under test conditions and specified conditions, it completes the computing tasks within a certain period of time: The number of floating point operations or integer operations: When the liquid-cooled server system is running under test conditions and specified conditions, during the same period of time, the liquid-cooled server itself The ratio of energy consumption to the total energy consumption of the liquid-cooled server system, the measurement unit is (W·h)/(W·h) (dimensionless quantity): When the liquid-cooled server system operates under test conditions and specified conditions, within the same period of time, the liquid-cooled server system The ratio of the calculation amount to the total energy consumption of the liquid-cooled server system, the measurement unit is (W·h)-1: When the liquid-cooled server system operates under test conditions and specified conditions, within the same period of time, the liquid-cooled server system The ratio of computing volume to liquid-cooled server energy consumption, the measurement unit is (W·h)-1: 3:7 Idle state idlemode The server operating system has been loaded, the user configuration file has been created, and only the system default basic applications are provided: state:
