【摘要】 大数据背景下,网络文件系统NFS作为一种成熟的分布式文件系统,为数据存储、管理提供了良好解决方案;So PC是基于软硬件协同设计的片上可编程系统,应用前景十分广泛。系统以SATA硬盘为存储介质实现了一个基于So PC的完整网络存储结构。重点介绍了如何在FPGA内嵌Micro Blaze处理器上设计实现NFS服务组件、文件系统软件,以及如何设计实现SATA硬盘控制硬件IP核。经Xilinx的XUPV5_LX110T开发平台调试验证,So PC网络存储软硬件系统工作正常,可以用作云存储的虚拟资源节点。更多还原

【Abstract】 NFS,network file system,is a mature distributed file system. It provides a solution to data storage and management in the era of big data. So PC,a programmable on-chip system,is based on hardware and software co-design. It has a wide application prospect. The system adopts SATA as its storage media to implement a network storage architecture based on SoPC. It focuses on how to implement NFS server component and file system on the Micro Blaze processor embedded in FPGA.Also,the implementation of the IP core of SATA hard disk control is the focal point. The design is debugged on the platform of XUPV5_LX110T of Xilinx. The result certifies that So PC network storage system works well and it can be used as the virtual resource node of cloud storage.更多还原
