| 数据中心节能和环境控制的基础是确定数据中心服务器的功耗。本文针对以CPU计算为主要任务的应用场景,搭建实验台,利用Lookbusy ,Stress ,SPECpower_ssj 2008三种测试软件,结合服务器运行参数,对服务器功耗和硬件利用率等进行测试分析,对比三种软件的应用效果。研究结果表明:不同测试软件对于服务器硬件资源的利用程度不同,导致服务器功耗也不同,功耗最大差异超过15% ,在服务器功耗模型的研究中,应当根据服务器应用场景和硬件利用率的差异选择不同的性能测试软件;其中,SPECpower_sj2008适合对服务器进行综合测试,而Stress适合测试服务器在极端情况下的运行稳定性。 |

| Abstract: |
| Determining the power consumption of data center servers is the basis of data center energy saving and environmental control. At present, it is a common research method that uses performance testing software to fit the server power consumption model under different working conditions. An experimental platform was built with the aim of CPU computing as the main task. Three different test software (Lookbusy, Stress, and SPECpower_ssj 2008) were used to conduct the test. This study compared the differences between server power consumption and hardware utilization based on server operating parameters. The results show apparent differences in server hardware calls under an identical parameter setting among different testing software, leading to a maximum deviation of more than 15% on the testing outcome of the server power consumption. This indicates that it is important to select the proper performance testing software according to application scenarios and hardware utilization when it comes to the research of the server power consumption model. Among the software tested, SPECpower_ssj 2008 is most suitable for the comprehensive testing of servers, and Stress is most suitable for testing the stability of servers under extreme conditions. |
