【摘要】：监狱是关押和改造犯罪人员的特殊场所，做好监狱的安保工作，有效防止犯罪分子越狱、暴狱、破坏，是保障社会和谐稳定的重要措施。随着信息化建设的不断发展，监狱的安保也充分利用现代先进的信息化资源，依托数字监控技术实现对监狱的全方位监控，采用远程视频、音频监控可以保证管理人员随时监控系统的现场状态，监狱监控系统日益成为监狱管理的有力工具，对犯罪分子具有极大地震慑作用。而随着监狱监控系统规模的日益增加和功能的不断扩展，传统模式的监狱监控存储系统已经很难满足大规模监狱监控数据存储的需求。本文从监狱监控存储系统的实际需求出发，分析了其在数据存储、高性能网络传输以及数据可靠性方面的需求，设计了基于Lustre文件系统的监狱监控存储系统，该系统可以充分满足系统对数据海量存储、高性能传输和高可靠性方面的需求。本文首先分析比较了Lustre和其他主流的分布式文件系统，提出Lustre文件系统用于监狱监控存储系统中的优越性，并给出了基于Lustre文件系统的监狱监控存储系统系统结构设计。同时针对网络带宽对系统传输性能的限制，提出利用InfiniBand网络构建其网络传输子系统的设计方案，充分利用InfiniBand网络高带宽、低延迟的特点，大大降低了数据传输的时延，通过与Lustre文件系统的无缝融合，保证了监控存储系统对存储系统性能的需求。本文还就监狱监控系统对数据可靠性的高度需求，提出了利用DRBD和Heartbeat技术构建高可靠的元数据器构架；利用RAID5构建系统的存储节点，使系统数据存储的可靠性得到了很大的加强，，满足了监控存储系统对高可靠数据存储的需求。最后，针对监狱监控存储系统数据传输的特点，通过工程实践，分别对Lustre文件系统服务器端和客户端进行优化配置，搭建了工程实验环境，对系统的性能进行了测试与验证，给出了测试结论，对充分发挥Lustre在监狱监控存储系统中的最佳性能具有重要的参考价值。
[Abstract]:Prison is a special place to detain and reform criminals. It is an important measure to ensure social harmony and stability to do a good job of prison security and effectively prevent criminals from escaping from prison, breaking into prison and destroying. With the continuous development of information construction, the security of the prison also makes full use of modern and advanced information resources, relying on the digital monitoring technology to achieve the all-round monitoring of the prison, the use of remote video, Audio surveillance can ensure the managers to monitor the status of the system at any time. The prison monitoring system has become a powerful tool for prison management and has a great deterrent effect to criminals. With the increasing scale of prison monitoring system and the continuous expansion of functions, the traditional prison monitoring storage system has been difficult to meet the needs of large-scale prison monitoring data storage. Based on the actual demand of prison monitoring and storage system, this paper analyzes its requirements in data storage, high performance network transmission and data reliability, and designs a prison monitoring storage system based on Lustre file system. The system can meet the requirements of mass data storage, high performance transmission and high reliability. This paper first analyzes and compares Lustre with other mainstream distributed file systems, proposes the superiority of Lustre file system in prison monitoring and storage system, and gives the structure design of prison monitoring storage system based on Lustre file system. At the same time, aiming at the limitation of network bandwidth on the transmission performance of the system, this paper puts forward a design scheme of using InfiniBand network to construct its network transmission subsystem, which makes full use of the characteristics of high bandwidth and low delay in InfiniBand network, and greatly reduces the delay of data transmission. Through the seamless integration with Lustre file system, the performance of monitoring storage system is ensured. According to the high demand for data reliability of prison monitoring system, this paper puts forward to use DRBD and Heartbeat technology to construct a high reliable metadata structure, to construct storage node of the system by using RAID5, to construct the storage node of the system, and to use RAID5 to construct the storage node of the system. The reliability of system data storage is greatly enhanced and the requirement of high reliability data storage in monitoring storage system is satisfied. Finally, according to the characteristics of prison monitoring and storage system data transmission, through engineering practice, the Lustre file system server and client are configured optimally, the engineering experimental environment is built, and the performance of the system is tested and verified. The test results are given, which have important reference value for giving full play to the best performance of Lustre in prison monitoring and storage system.
