Abstract

A load scheduling algorithm for the virtual server cluster which is suitable for the storage system is proposed to solve the problem of uniform load distribution of the current virtual server cluster, according to the characteristics of the storage system. This method, which analyzes the selection schemes of each index's weight, is based on the real server's state collection feedbacks periodically to the load balancer to make decisions. The result of experiment shows that this algorithm can make the external response performance (time to last byte) of the cluster system reach a higher level, and make the internal load performance of system (balance of disk usage) reach a more balanced state.

基于状态获取和动态反馈的存储系统负载均衡调度算法
针对当前虚拟服务器集群负载分布不均的问题,根据存储系统的特点,提出了一种适用于存储系统的虚拟服务器集群负载调度算法。该方法分析了各指标权重的选择方案,并根据实服务器的状态集合定期反馈给负载均衡器进行决策。实验结果表明,该算法可以使集群系统的外部响应性能(到最后一个字节的时间)达到更高的水平,并使系统的内部负载性能(磁盘使用平衡)达到更平衡的状态。
