摘　　要：针对视频清晰度过高导致存储容量不足以及处理耗时长的问题,设计基于LSM树的视频数据扩容存储系统。利用EMCX4-480磁盘阵列储存备份数据,使用FPGA实现数据缓存管理与控制。应用LSM树控制存储过程中出现的延迟问题,并通过分割机制计算数据节点的分割存储数量,由此完成系统扩容。利用LSM树组织视频数据,应用概率描述存储期望值,实现视频数据扩容存储。由实验结果可知,该系统能够将所有视频数据存储在系统中,且数据存储最大耗时为179 ms,能够达到在短时间内实现全部视频数据有效存储的目的。Design a video data expansion storage system based on LSM tree to address the issues of insufficient storage capacity and long processing time caused by high video clarity.Utilize EMCX4-480 disk array to store backup data,and use FPGA to achieve data cache management and control.Apply LSM tree to control the latency issues that occur during stored procedures,and calculate the number of segmented storage for data nodes through a segmentation mechanism to achieve system expansion.Using LSM tree to organize video data,applying probability description to store expected values,and achieving video data expansion and storage.According to the experimental results,the system can store all video data in the system,and the maximum data storage time is 179 ms,which can achieve the goal of effectively storing all video data in a short period of time.
