一种基于国产FPGA的NAS存储系统设计与实现OA

Against the dual backdrop of the accelerated advancement of domestic independent innovation and the explosive growth in de-mand for AI computing power,the localization of core underlying disk control technologies in storage systems remains inadequate.To address this issue,this paper designs and implements a SATA-standard NAS storage system based on the domestic software and hard-ware ecosystem.Its core hardware architecture adopts the Fudan Microelectronics FPGA and the Loongson 3A3500 processor,with the software layer built on the Kylin Linux operating system.The FPGA realizes the bridge conversion between the PCIe and SATA proto-cols,encompassing core functions such as high-speed PCIe data interaction,HBA controller logic,and SATA protocol processing.On this basis,combined with RAID redundant storage technology,a NAS storage management system integrating volume group manage-ment and multi-protocol file sharing is further designed and implemented.This work provides a feasible technical approach and practical solution for the localization of storage systems.
