摘要
由于服务器资源利用率偏低且资源负载不均衡,使得数据中心能耗浪费严重。针对上述情况,提出基于虚拟机迁移的数据中心节能调度方法。该方法通过选择合适的迁移时机、迁移对象和目标主机,完成虚拟机迁移前的准备工作,然后基于迭代-停止迁移方法对服务器进行动态迁移和整合,从而减少服务器的运行数量,以此最小化数据中心能耗。实验结果表明,该方法能有效提高服务器资源利用率,减少服务器的冗余数量,提高数据中心整体能效。
Since the server resources utilisation is low and the resources load is unbalanced, the energy waste of data centre is serious. In view of this, we proposed a virtual machine migration-based data centre energy-saving scheduling method. Through selecting proper migration time, migrate object and target host, this method completes the preparatory work before the migration of virtual machine. Then, it dynamically migrates and integrates the servers based on the iteration-stopping migration method, so that minimises the energy consumption of data centres by reducing the running number of the servers. Experimental results showed that this method could improve the server resources utilisation effectively, reduce the redundant number of servers, and improve the overall energy efficiency of data centre.
