一种网络存储技术新方案--智能网络磁盘集群存储系统

A New Network Storage Scheme-intelligent Network Disk Cluster Storage System

针对网络存储技术中存在的一些问题,提出一种网络存储技术新方案——智能网络磁盘集群存储系统.通过"分散服务、集中管理"模式,有效解决了普遍存在的单点失效问题;通过设计一种虚拟文件系统,将多个存储节点虚拟成一个超大容量、集中化的数据存储中心,满足了海量信息存储的大容量、可扩展性等要求;通过多数据布局方法,满足了数据完整性和吞吐率等不同数据存储要求;最后分别提出了一种智能I/O调度和自适应负载均衡方案.

To solve some problems of network storage technology, a new scheme named intelligent network disk cluster storage system （INDCSS for short） is proposed. First, INDCSS efficiently solves the problem of single failure point by adopting a model of decentralized service and centralized management. Second, it integrates multi storage nodes into a large capacity and centralized storage pool with the help of a virtual file system, which can provide greater capacity and higher scalability. Third, it can satisfy the requirements of data integrity and throughput by using two kinds of data layouts simultaneously. Finally, it designs a scheme of intelligent I/O schedule and a method for self-adaptive load balancing of multi-nodes.
