摘要
为了降低IaaS云中物理服务器的资源开销和能耗,提出了一种资源损耗模型;同时结合服务器能耗模型,提出了一种能耗和资源损耗优化的虚拟机放置策略;设计并实现了一种能耗有效且物理资源损耗优化的多目标虚拟机放置算法。仿真实验结果表明,该算法不仅能有效地降低物理服务器的能源消耗,同时能较好地控制物理资源损耗,从而实现节能减排,具有较强的理论和现实意义。
In order to reduce the power consumption and server physical resources astage in IaaS,a resource wastage model is established.By incorporating energy consumption model of servers,a virtual machine placement strategy is proposed for optimizing the consumption of resource and energy.Moreover,this paper designs and implements a multi-objective virtual machine placement algorithm to achieve the energy efficiency and optimization of physical resource.Finally,it is shown from simulation results that the proposed algorithm not only effectively reduces the energy consumption of server cluster but also improves the utilization ratio of server physical resource simultaneously.
