    Distributed Layered Resource Management Model in Blue Whale Distributed File System

    • 摘要: 为了高效地管理海量分布式存储资源,蓝鲸分布式文件系统抛弃了传统的集中式资源管理方式,实现了分布式分层资源管理模型.该模型可以管理多个存储服务器,还能支持多个元数据服务器组成的集群进行分布式元数据处理,支持各种元数据和数据的负载平衡策略.同时,该模型中的带外数据传输功能克服了系统的性能瓶颈,提高了系统支持并发访问的能力.理论分析和实际测试结果都表明此模型能够满足多种不同的需求,提供很好的性能和良好的扩展性.

       

      Abstract: In order to manage massive storage efficiently, Blue Whale distributed file system discards the traditional central resource management model, and adopts a distributed layered resource management model. This model supports multiple storage nodes and a cluster of metadata servers. The out-of-band data transportation alleviates the bottlenecks of performance, and enables metadata server cluster to handle metadata concurrently and efficiently, and also provides load balancing in the system. Theoretical analysis and test results show that this model outperforms in capability and scalability in various circumstances.
