摘要： 为降低数据中心的能量消耗，提出一个具有2层能耗模块结构的数据中心能耗有效性系统框架EADC，其中，虚拟环境管理子系统通过节点状态的按需变化降低能耗，数据中心管理子系统通过控制节点在应用间的按需切换满足其所有的服务需求。测试结果表明，ECDA可在满足能耗与性能要求的前提下实现能耗最低。

Abstract: In order to reduce the energy consumption in data center, its energy consumption effectiveness is researched with a framework named EADC. In the framework, there are two types of modules: Virtual Environment Manafement System(VEMS) and Data Center Manafement System(DCMS), which put down the energy usage by changing the status of computing nodes(VEMS) and satisfy the Quality of Service(QoS) by controlling the nodes migration among VEs(DCMS). Test results shows that EADC makes data center achieve the balance between energy consumption and performance, it has the lowest energy consumption while meeting the QoS.

Key words: data center, Quality of Service(QoS), energy consumption effectiveness, performance model, resource placement
