摘　　要：随着气象事业发展,非结构化数据海量增长,针对传统非分布式、直联式存储方式支撑能力受限问题及对存储系统需要支持大容量、集中管理、高可扩展性、高可靠性的新需求出发,利用网络附加存储,采用分布式架构、堆叠组网冗余和纠删码冗余保护机制、运用NFS、CIFS、FTP等协议,搭建一个分布式架构集群存储系统,通过分布式文件系统对外提供统一网络存储空间,通过CIFS、NFS、FTP三种方式实现文件共享。解决旧系统存储能力不足、动态扩展性差、效率不高、可靠性和安全性低的问题,进一步提升重庆气象数据云平台基础支撑能力。With the development of meteorological informatization, the unstructured meteorological data is growing massively. To solving the problem of the storage capacity limitation to the non-distribute storage system and in order to meet the needs of large storage capacity,centralized management, high scalability and high reliabilityof the storage system, a fully symmetrical distributed architecture cluster storage system which is used distributed architecture, stack networking redundancy , erasure code redundancy protection mechanism and NFS,CIFS,FTP and other protocols is builded based on major network attached storage .This system provides unified network storage space through distributed file system and realizes file sharing through CIFS, NFS and FTP protocols.It solves the shortages of insufficient storage capacity, poor dynamic scalability, low efficiency, lowreliability and low safety of unstructured data.
