| 摘 要： | 传统容灾系统后台存储采用灾备中心直接磁盘存储的方法,该方法存在集中存储带来的一系列问题,如存储数据易损坏、存储能力无法在线扩展以及随着磁盘容量的增大存储性能会不断下降等。针对这些问题,设计并实现了一种支持集群存储的容灾系统。通过在容灾系统后台部署GlusterFS分布式文件系统,实现了数据的分布式和副本化存储,数据存储的安全性、可扩展性和存储性能均得到了极大的改进,很好地克服了上述问题。

| Abstract: | Traditional disaster tolerance system use direct attached storage as the back method has series problems such as the backup-data is easy to damage, the storage performance will decrease as the disk capacity extends. According to these problems, storage is designed and implemented. By deploying GlusterFS file system at the back end above were overcome. end storage of disaster recovery center. This capacity cannot extend online, and the storage a disaster tolerance system supporting clustered of the disaster tolerance system, these problems |
