摘要: 本文针对目前云数据中心主机服务器在空转时间段对能源消耗巨大的问题，建立了虚拟资源申请–分配模型，提出了一种虚拟资源分配的策略。该策略在满足用户需求前提下，对主机服务器最大化利用，以此来降低基础设施对能源的消耗。通过“端”对云任务进行统计综合，提交云中心，云中心的资源管理器对云任务进行统一分配，以达到对服务器的最佳利用。仿真结果表明，我们提出的策略对不同任务数目、类型的云任务调度具有较好的效果，能够提高云计算中心服务器的利用率。
Abstract:
In this paper, a virtual resource application-allocation model and an efficient virtual resource al-location strategy are presented aiming at the huge energy consumption problem during the idle time of host server in cloud data center. The strategy can maximize the use of the host server and reduce energy consumption of the infrastructure under the premise of meeting the users’ needs. The cloud tasks are submitted to the cloud center after the statistical synthesis at the ends of the cloud, and unified allocated by the resource manager of cloud center in order to achieve optimal utilization of the servers. Simulation results show that our proposed strategy has good effect for different number and type of cloud tasks scheduling, and can improve the utilization of cloud computing center server.
