为解决远程容灾系统中出现的存储服务器负载不均衡现象,提出一种动态负载均衡方法,该方法首先对用户的任务进行排队,并结合动态反馈原理,周期地根据远程容灾系统各存储服务器的真实负载变化情况,进行任务分发,避免了系统内部存储节点间的负载不均.仿真实验证明,相对于传统的动态负载均衡算法WLC,该方法明显地提高了系统的吞吐量.
In order to solve the load imbalance problem in disaster tolerant system, a requests reordering method and an dynamic feedback dispatch load-balancing solution are provided. The approach aims to balance the request load of the storage server by changing the dispatch strategy according to the load of the storage server node periodically. The experiments show that the algorithm can improve the throughput of system, compared with troditional load-balancing solution.
