| 摘 要： | 针对当前集群文件系统缺乏动态扩展性和高可用性的不足,提出了一种基于逻辑矢量环结构的集群文件系统HANDY.系统利用逻辑矢量环实现动态扩展和资源的动态管理,采用了分布式元数据管理策略,引入邻接复制技术实现元数据的容错,通过可定制的数据存放策略满足不同应用的数据存储需求.测试结果表明,基于环状结构的系统HANDY具有良好的动态扩展性和高可用性.

| Abstract: | Most of existing cluster file systems are shortage of dynamic scalability and high availability,so we provide a new cluster file system based on logical vector rings,named HANDY.It adopts logical vector rings to implement distributed management of metadata and dynamic management of storage resource.Through neighbor replication mechanism,it provides high availability of metadata.In addition,a flexible,customized data distribution scheme is employed in HANDY,which meets storage requirements of all kinds of different applications.The experimental results show that HANDY cluster file system based on logical vector rings achieves good dynamic scalability and high availability. |
