| 摘 要： | 云存储系统具有高容错性、部署在低廉的硬件上、易扩展性、提供高传输率访问数据的优点,但是在云存储环境下的HDFS架构中,原有的数据节点选择策略有可能造成大文件存储负载不均衡,从而影响整个系统的性能。针对这一问题,综合考虑多个因素对其进行改进,提出了设备选择策略算法,用以均衡系统的负载。并设计仿真实验,验证了算法的有效性。

| Abstract: | Cloud storage has the advantages of high fault tolerance,easy expansibility,providing high speed of data access and cheap hardware.However,there is a problem that the initial data selection strategy may lead to the load unbalance.This problem can be solved.Considering various factors and the characteristics of distributed file system of cloud storage,provide a new data selection strategy in order to balance the load.The experiment presents that the performance and effectiveness of new strategy are improved. |

| Keywords: | HDFS load balance cloud storage selection strategy |
