冷存储在铁路视频监控系统的文件接口研究

铁路综合视频监控系统在数字化、高清化、结构化、存储更集中、存储时间更长等方面进步迅速,正逐步向基于云的视频服务方向发展。传统IP-SAN及X86服务器的存储方案会使海量数据的存储成本、能源消耗、机房空间及管理压力越来越大,创建一种基于云的冷存储层(简称冷存储)成为大势所趋。对于冷存储,文件系统接口如何最大程度地简化用户操作,提高其工作效率,成为需要解决的重点问题。将冷存储技术与铁路综合视频监控系统相结合,开展冷存储技术的文件系统接口研究和测试分析。

Research on File Interface of Cold Storage in Railway Video Surveillance System

The integrated railway video surveillance system is progressing rapidly in terms of digitization,high definition,structuring,storage concentration and storage time.It is gradually developing towards cloud-based video services.The storage solutions of traditional IP-SAN and X86 server will increase the storage cost,energy consumption,machine room space and management pressure of massive data.It is an irresistible trend to create a cloud-based cold storage layer(referred to as cold storage).For cold storage,how the file system interface minimizes user operations and improves its work efficiency becomes a key issue that needs to be addressed.In this paper,the cold storage technology is integrated with the railway video surveillance system for the research and test analysis on the file system interface of cold storage technology.
