【摘要】：監(jiān)獄是關(guān)押和改造犯罪人員的特殊場所，做好監(jiān)獄的安保工作，有效防止犯罪分子越獄、暴獄、破壞，是保障社會和諧穩(wěn)定的重要措施。隨著信息化建設(shè)的不斷發(fā)展，監(jiān)獄的安保也充分利用現(xiàn)代先進的信息化資源，依托數(shù)字監(jiān)控技術(shù)實現(xiàn)對監(jiān)獄的全方位監(jiān)控，采用遠程視頻、音頻監(jiān)控可以保證管理人員隨時監(jiān)控系統(tǒng)的現(xiàn)場狀態(tài)，監(jiān)獄監(jiān)控系統(tǒng)日益成為監(jiān)獄管理的有力工具，對犯罪分子具有極大地震懾作用。 而隨著監(jiān)獄監(jiān)控系統(tǒng)規(guī)模的日益增加和功能的不斷擴展，傳統(tǒng)模式的監(jiān)獄監(jiān)控存儲系統(tǒng)已經(jīng)很難滿足大規(guī)模監(jiān)獄監(jiān)控數(shù)據(jù)存儲的需求。本文從監(jiān)獄監(jiān)控存儲系統(tǒng)的實際需求出發(fā)，分析了其在數(shù)據(jù)存儲、高性能網(wǎng)絡(luò)傳輸以及數(shù)據(jù)可靠性方面的需求，設(shè)計了基于Lustre文件系統(tǒng)的監(jiān)獄監(jiān)控存儲系統(tǒng)，該系統(tǒng)可以充分滿足系統(tǒng)對數(shù)據(jù)海量存儲、高性能傳輸和高可靠性方面的需求。 本文首先分析比較了Lustre和其他主流的分布式文件系統(tǒng)，提出Lustre文件系統(tǒng)用于監(jiān)獄監(jiān)控存儲系統(tǒng)中的優(yōu)越性，并給出了基于Lustre文件系統(tǒng)的監(jiān)獄監(jiān)控存儲系統(tǒng)系統(tǒng)結(jié)構(gòu)設(shè)計。同時針對網(wǎng)絡(luò)帶寬對系統(tǒng)傳輸性能的限制，提出利用InfiniBand網(wǎng)絡(luò)構(gòu)建其網(wǎng)絡(luò)傳輸子系統(tǒng)的設(shè)計方案，充分利用InfiniBand網(wǎng)絡(luò)高帶寬、低延遲的特點，大大降低了數(shù)據(jù)傳輸?shù)臅r延，通過與Lustre文件系統(tǒng)的無縫融合，保證了監(jiān)控存儲系統(tǒng)對存儲系統(tǒng)性能的需求。 本文還就監(jiān)獄監(jiān)控系統(tǒng)對數(shù)據(jù)可靠性的高度需求，提出了利用DRBD和Heartbeat技術(shù)構(gòu)建高可靠的元數(shù)據(jù)器構(gòu)架；利用RAID5構(gòu)建系統(tǒng)的存儲節(jié)點，使系統(tǒng)數(shù)據(jù)存儲的可靠性得到了很大的加強，，滿足了監(jiān)控存儲系統(tǒng)對高可靠數(shù)據(jù)存儲的需求。 最后，針對監(jiān)獄監(jiān)控存儲系統(tǒng)數(shù)據(jù)傳輸?shù)奶攸c，通過工程實踐，分別對Lustre文件系統(tǒng)服務(wù)器端和客戶端進行優(yōu)化配置，搭建了工程實驗環(huán)境，對系統(tǒng)的性能進行了測試與驗證，給出了測試結(jié)論，對充分發(fā)揮Lustre在監(jiān)獄監(jiān)控存儲系統(tǒng)中的最佳性能具有重要的參考價值。
[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.
