基于SATA3.0的存储系统优化设计

An optimized design of a storage system based on SATA3.0

针对遥测试验中,获取的高分辨率、高帧频的大容量图像数据的实时存储以及传输稳定性问题,对存储系统进行了优化设计。该系统以Kintex 7系列FPGA为控制核心,将接收到的大容量图像通过SATA3.0传输总线,存储到固态硬盘中,并且优化了链路状态机,通过实时标志监测解决了传输中断的问题。存储完成后,通过千兆以太网将固态硬盘中的数据读取到上位机进行回放和分析。在常温以及-40℃和+60℃条件下完成大量的读写测试,结果表明,优化后的存储系统可以完成高速率、长时间的稳定存储,在大容量存储方面具有很好的参考价值。

Aiming at the problem of real-time storage of high resolution,high frame frequency and large capacity image data obtained in telemetry test,as well as the problem of transmission stability,we optimized a storage system.This system takes 7 series FPGA as the control core,and stores the received large-capacity image into the solid state hard disk through SATA3.0 transmission bus.The state machine is optimized in the stored procedure to solve the problem of transmission interruption through the real-time marker monitoring.After the storage was completed,the data in the SSD will be read through the gigabit Ethernet to the computer for playback and analysis.Lots of reading and writing data were completed at room temperature and-40℃and+60℃.The results show that the optimized storage system can achieve high speed and long time stable storage and has a good reference value in large capacity storage.
