Design and implementation of large⁃scale network data storage system

传统网络数据存储系统存在各种各样的缺陷,因此设计并实现了大规模网络数据存储系统。该系统通过A/D网络数据采集模块使用A/D变换器转化网络模拟信号为数字信号,传递至FPGA网络数据接收模块展开接收并处理,处理后的网络数据传递至FLASH数据存储模块,该模块通过读取、擦除、编程等操作保证网络数据的完整性和可靠性实现网络数据存储。系统软件采用超高密度数据存储分布空间结构模型,通过尺度伸缩降低存储冗余,在网络数据集合空间范围内分割网络数据存储特征,优化网络数据存储。经实验分析,该系统大规模网络数据存储速度良好,响应速度快,负载均衡存储性能良好。

As the traditional network data storage system has a variety of defects,a large⁃scale network data storage system is designed and implemented.The A/D converter is used in the system to convert network analog signals into digital signals by A/D network data acquisition module,and transmit it to FPGA network data receiving module for receiving and processing.The processed network data is transmitted to Flash data storage module to ensure the integrity and reliability of network data by means of the reading,erasure,programming and other operations,and realize the storage of network data.In the system′s software,the spatial distribution structure model of ultra⁃high density data storage is adopted to reduce the storage redundancy by scaling,segment the features of network data storage in the network data set spatial range,and optimize the network data storage.The experimental analysis results show that the system has high storage velocity,fast response speed and exellent load balancing storage performance for large⁃scale network data.
