Design Of A Universal High-Speed Data Storage System And Data Management Technology

With the rapid development of modern information technology,the electromagnetic environment of modern battlefields has become increasingly complex and varied.The operational effectiveness of conventional electronic warfare methods has also gradually declined.New radars,unknown signals,and complex waveforms emerge on the battlefield,and electromagnetic space is added.In the case of spectrum congestion,the data volume forms explosive growth,signal resolution and sampling frequency of the receiver front end,and the storage capacity,storage bandwidth and system versatility and reliability of the electronic countermeasure information data storage system are proposed.higher requirement.In order to solve the above problems,and provide a reliable offline processing container for intelligent processing of electronic warfare information,a scientific and reasonable storage scheme is designed for the massive signal parameters in the field of electronic countermeasure information processing,which is the hardware cornerstone for realizing information processing in modern electronic warfare.This paper firstly carried out the demand analysis of high-speed data storage system and the introduction and comparison of high-speed storage technology.On this basis,the main work of this paper is carried out.The main work of the thesis is as follows: 1.The overall architecture design of the system,the system uses a decentralized architecture to divide the system into upper user nodes and lower storage nodes.The upper user node is the system management software in the user control computer,and its main function is to realize the user to the underlying system management and storage node information query.The underlying storage node mainly completes the storage and upload function of high-speed data sources outside the system.A single storage node can provide 8TB of storage capacity and 3.2GB/s of storage bandwidth.2.Combined with the overall design and requirements analysis of the system,the Xilinx XC7K355 T chip and TI TMS320C6455 chip are taken as the core,and the Samsung SSD860EVOmSATA1 TB solid-state disk array is used as the storage medium to build the storage node(storage control board)hardware platform.The high-speed data storage and uploading logic software in the storage node is designed,and the fiber data stream,the VPX data stream and the uploaded data stream are analyzed respectively,and the system stores the fiber data stream and the VPX data stream and the storage medium.Upload of internal data.3.According to the application scenario of this system,a set of system data management scheme is designed.According to the characteristics of the system decentralized architecture,the internal data management of a single storage node is first designed,including the design of management modules such as file system module,RAID0 array control module,command transceiver module,and the design of data management working mode based on it..Finally,from point to point,complete management and task assignment of the entire system node network.4.Set up a test platform to test and verify the storage performance and management functions of the system.It includes testing the read/write speed and signal quality of the storage interface in the system,testing the storage and upload modules in the system,and verifying the function of the system data management scheme.The test results prove the correctness and feasibility of the design of the system,and at the same time realize the user's management of the stored data in the system.
