Abstract: Large scale data centers need to consume a large amount of power,resulting in high operating costs and other issues such as environmental pollution.In order to reduce the energy consumption of the data center,we constructed a management model of the data center and proposed the algorithm of the static placement algorithm and dynamic adjustment of the virtual machine.Dynamic migration of virtual machine can effectively reduce the energy consumption while improving resource utilization.However,excessive migration of virtual machines will affect the quality of the application and cause SLA violation.In the dynamic adjustment stage,we adopted dynamic thresholds to control the virtual machine migration and reduce energy consumption.Finally,we used CloudSim to do a lot of experiments.The results show that the energy-aware management of virtual machine (EAMVM) mechanism can reduce energy consumption and reduce the number of virtual machine migration. 〖BHDWG1,WK42,WK43,WK42W〗第10期 朱德剑 ,等:数据中心虚拟机节能管理机制
