【摘要】：近年来,数据中心庞大的能源开销问题引起广泛关注.虚拟化管理平台可以通过虚拟机迁移技术将虚拟机整合到更少的服务器上,从而提高数据中心能源有效性.对面向数据中心节能的虚拟机整合研究工作进行调研,并总结虚拟机整合研究存在的3个挑战.针对已有工作未考虑虚拟机等待资源调度带来的服务器资源额外开销这种现象,开展了资源调度等待开销感知的虚拟机整合研究.从理论和实验上证明了在具有实际意义的约束条件下,存在着虚拟机等待资源调度带来的服务器资源额外开销,且随着整合虚拟机数量的增长保持稳定.基于典型工作负载的实验结果表明,这个额外开销平均占据了11.7%的服务器资源开销.此外,提出了资源预留整合(MRC)算法,用于改进已有的虚拟机整合算法.算法模拟实验结果表明,MRC算法相比于常用的虚拟机整合算法FFD(first fit decreasing),明显降低了服务器资源溢出概率.
[Abstract]:In recent years, the huge energy cost of data center has attracted much attention. Virtualization management platform can integrate virtual machine into fewer servers through virtual machine migration technology. In order to improve the energy efficiency of data center, the research work of virtual machine integration for data center energy saving is investigated. Three challenges of virtual machine integration research are summarized. The phenomenon of server resource overhead caused by virtual machine waiting resource scheduling is not considered in the existing work. The research on virtual machine integration of resource scheduling wait overhead awareness is carried out, and it is proved theoretically and experimentally that under the constraint condition of practical significance. There is the additional cost of server resources caused by virtual machine waiting for resource scheduling, and it is stable with the increase of the number of integrated virtual machines. The experimental results based on typical workload show that. This extra cost accounts for an average of 11.7% of the server resource overhead. In addition, a resource reservation integration algorithm is proposed. It is used to improve the existing virtual machine integration algorithm. The simulation results show that the FFD(first fit algorithm is better than the traditional virtual machine integration algorithm. Significantly reduced server resource overflow probability.
