摘要: 为了提升使用虚拟化技术的数据中心的能耗利用率,根据处理器DVFS(dynamic voltage and frequency scaling)变频技术的功耗特性,论证了在理想情况下,数据中心中所有处理器频率一致时能耗利用率最高;基于这一理论,提出了云计算中心的负载平衡方法;最后在CloudSim中进行了仿真实验,实验结果显示该方法能够优化数据中心的能耗。

Abstract: In order to improve the power usage utilization of datacenter of using virtualization technology, according to the consumption character of DVFS (dynamic voltage and frequency scaling), this paper firstly proves that datacenter will consume lowest power at the case all CPU frequencies are the same. Based on the conclusion, it proposes the load balance scheme in datacenters. Finally, it simulates this model in CloudSim. Experimental results show that the model can optimize the power consumption of datacenter.
