With development of networked storage and its applications, united storage network (USN) combined with network attached storage (NAS) and storage area network (SAN) has emerged. It has such advantages as high performance, low cost, good connectivity, etc. However the security issue has been complicated because USN responds to block I/O and file I/O requests simultaneously. In this paper, a security system module is developed to prevent many types of atl~cks against USN based on NAS head.The module not only uses effective authentication to prevent unauthorized access to the system data, but also checks the data integrity.Experimental results show that the security module can not only resist remote attacks and attacks from those who has physical access to the USN, but can also be seamlessly integrated into underlying file systems, with little influence on their performance.  相似文献

为了改进网络存储设备的I/O速度和系统性能, 设计了一种新的专用存储服务器, 该服务器是一种基于iSCSI的附网存储服务器 (iSCSI-based network-attached storage server, iNAS). 在iNAS中, 利用iSCSI软件提供的模块, 使得iNAS同时提供file I/O 和block I/O服务, 实现了NAS和SAN (storage area network)的融合; 通过在RAID (redundant array of inexpensive disks)控制器和用户内存之间的直接数据传输(零拷贝), 极大地提高了iNAS的I/O响应速度; 通过一个多级分流的的设备驱动程序, 将多个RAID整合成单一的存储池, 从而实现了存储虚拟化. 实验结果显示, iNAS对文件I/O请求和块I/O请求都具有极高的响应速度.  相似文献
