附网络存储NAS是一种将分布、独立的数据整合为大型、集中化管理的数据中心,以便对不同主机和应用服务器进行访问的技术[1]。本文提出一种以ARM9微处理器EP9315和嵌入式Linux操作系统构建附网络存储系统的设计方案;对系统的体系结构、硬件设计、操作系统的移植、驱动程序和应用程序的开发等设计要点作了相关研究和讨论。 Network Attached Storage NAS is a technology that integrates distributed, independent data into a large, centrally managed data center for access to different hosts and application servers [1]. In this paper, a design scheme based on ARM9 microprocessor EP9315 and embedded Linux operating system is proposed. The system architecture, hardware design, porting of operating system, development of drivers and applications Related research and discussion.
