摘要
针对当前网络存储系统中存在的问题,提出了基于智能算法的智能网络磁盘IND的存储方案,探讨了IND系统的结构,设计了相应的应用协议,实现了智能网络磁盘调度算法。通过应用协议实现了对外虚拟存储,并将文件服务器分放到智能磁盘,避免了单点故障和性能瓶颈。通过对多个磁盘的并行调度算法,实现了并行传输,提高了文件的传输速度。以此为基础,设计和实现了IND模拟程序。试验结果显示,智能网络磁盘有助于避免单点故障,提高数据文件的传输效率。
Aiming to solve the problem in network storage system, this paper proposes a scheme named intelligent network disk based on the intelligent arithmetic, discusses the construction of the IND system frame, designs correlative protocols, and implements intelligent arithmetic. A virtual storage via protocol is achieved, single nod exception and capability choke point is avoided via transferring the function of file server down, to IND, and a parallel file transfer via the intelligent scheduling arithmetic in IND is implemented. A simulating program is designed and implemented. Experimental results show that IND helps avoid single nod exception and improves the file transfer efficiency.
