网络公用存储的可靠性与灾备技术

随着网络和存储技术的发展，提供可共享和便捷使用的网络公用数据存储服务已成为互联网的一种重大新型应用模式和发展趋势，这对存储可靠性与灾备等方面提出了巨大挑战。本项目针对大规模网络公用数据存储，研究主要集中在存储设备基础层和系统管理与构建层，具体在如下四个方面展开研究：1.网络公用存储可靠性模型及灾备结构研究；2.大规模存储阵列设备的可靠性；3.分布式存储系统级的可靠性研究；4.远程灾备关键技术研究。通过本项目的研究，冀突破大规模网络公用数据存储中心建设中的存储可靠性与灾备的关键技术，以满足重要行业和部门信息对网络公用存储的需要。

With the rapid development of networks and storage technologies, providing a shared and convenient network public storage service has become an important application mode and developing trend of Internet service, which brings tremendous challenges to the storage reliability and the data backup and disaster recovery system. To improve the reliability of large-scale network public storage, we propose four main research topics focusing on the storage device level, system management level and construction level: 1. the reliability model of network public storage service and the architecture of data backup and disaster recovery system; 2. the reliability of large-scale storage device/array; 3. the reliability of distributed storage systems; 4. The key technologies of remote data backup and disaster recovery system. Through above research, we expect to propose some key technologies and the solutions for building a large-scale network public storage system and the data backup and disaster recovery system, satisfying the public storage requirements of industries and important departments.
