摘　　要：在雷达、通信、电子对抗等数据存储应用领域,为满足大容量SATA固态盘存储阵列的持续稳定高速写盘要求,设计了一种基于FPGA的RAID0存储阵列系统。该系统以FPGA作为数据处理核心芯片,实现了数据接收、数据缓存、数据传输、数据存储等功能。根据SATA固态盘垃圾回收的特性,设计并优化逻辑功能模块。经反复测试验证,16路SATA固态盘存储容量达32 TB,写入带宽高达5.5 GB/s,在工业温度环境下能长时间稳定工作。In the domain of data storage applications such as radar,communication,and electronic countermeasure,in order to meet the requirements of writing large capacity SATA Solid State Disk Array(SSD)continuously,steadily and high-speedily,a RAID0 storage array system based on FPGA is designed.This system takes FPGA as the data processing core,which realizes functions such as data receiving,data buffering,data transmission,and data storage.According to the garbage collection characteristic of SATA SSD,logic function modules are designed and optimized.The repeatable tests show that sixteen SATA SSD has the storage capacity up to 32 TB,writing bandwidth up to 5.5 GB/s,and the ability to work steadily for a long time in the industrial environment.
