Rapid Framing mass storage system on the Internet

Wuhan University Journal of Natural Sciences 2000年第3期5卷 293-297页

作者： Wang Fang Zhang Jiang-ling Huazhong Univ of Science and Technology Wuhan China

mass storage system is now very important for storing huge volume of data in many application system such as VOD systems, electronic library, scientific computation and so on. Besides the storage device and network devices, the real performance of mass storage system is greatly influenced by the connection way between the host and storage system. Here we propose a new design of mass storage system by promoting the storage devices' functions and involving, them directly into data delivering. It can easily meet the demands both for capacity and I/O bandwidth in those applications, and has better service quality and performance compared with the traditional system in delivering mass data over network.

Highly scalable metadata distribution algorithm in mass storage system

Journal of Shanghai University(English Edition) 2008年第5期12卷 419-425页

作者：吴伟谢长生黄建忠张成峰 National storage system Laboratory School of Computer Science Huazhong University of Science and TechnologyWuhan 430074 P. R. China

Distribution of metadata in a metadata server cluster is important in mass storage system. A good distribution algorithm has a significant influence on the system performance, availability and scalability. Subtree partition and hash are two traditional metadata distribution algorithms used in distributed file systems. They both have a defect in system scalability. This paper proposes a new directory hash （DH） algorithm. By treating directory as the key value of hash function, implementing concentrated storage of metadata, pipelining operations and prefetching technology, DH algorithm can enhance the system scalability on the premise without sacrificing system performance.
