New technologies are being developed and evolving at a very fast pace today. Although some of them are designed to solve a particular problem, as a whole these new technologies have created a big impact on existing computing and communication environments. Many recently developed applications are also demanding changes. For example, a number of fast growing applications like streaming video, data mining, and scientific visualization demand for larger and faster storage systems. However, the existing computer systems are too slow to react to these required changes as well as take advantages of new technologies. In this talk, Dr. David Du will present past and current research activities that are related to network attached storage systems. He has taken a fully integrated approach to carry out this research from applications to scalable servers. His focus is using PC/Workstation clusters and InfiniBand based servers to support these applications from servers to network attached storage and storage area networks. Dr. Du has focused on the performance and usage of FC-AL, SSA, and iSCSI (SCSI over Internet). Based on network attached storage, his goal is to design and develop computer systems that can take advantage of the newly developed technologies including active disks, object storage devices, disk-based XOR, iSCSI, and silicon-based TCP/IP offloading engines as well as to react to the required changes from applications. This talk will give a high-level overview of his effort in this area.


Dr. David H.C. Du received a B.S. degree in mathematics from National Tsing-Hua University, Taiwan, R.O.C. in 1974, as well as a M.S. and Ph.D. degree in computer science from the University of Washington in Seattle for 1980 and 1981, respectively. He is currently a Professor at the Computer Science and Engineering Department at the University of Minnesota in Minneapolis. His research interests include multimedia computing, storage systems, high-speed networking, high-performance computing over clusters of workstations, database design and CAD for VLSI circuits. Dr. Du has authored and co-authored more than 160 technical papers, including 75 revered journal publications in his research areas. Dr. Du is an IEEE Fellow and was an editor of IEEE Transactions on Computers from 1993 to 1997. He is currently serving on the editorial board of "Journal of Cluster Computing," "Journal of Parallel and Distributed Computing Practices" and the "Journal of Information Sciences and Engineering." He has also served as a guest editor for a number of journals including "IEEE Computer," "IEEE and Communications of ACM" and served as Conference Chair and Program Committee Chair to several conferences in multimedia and database areas.
