Tutorial #2 Tutorial type: half-day Authors: Prof. Dhabaleswar K. (DK) Panda, The Ohio State University Dr. Weikuan Yu, Oak Ridge National Laboratory Title: Storage Networks, Protocols and File Systems: Latest Trends? Description: With the advances of modern interconnects and networking protocols, the designs for storage and file systems are going through rapid changes. This tutorial will provide an overview of these emerging trends and the ongoing R&D efforts in these directions. The tutorial will start with an overview of different storage networking architectures and protocols including the IP-based storage networking protocols (FCIP/iFCP/iSCSI) and the latest ones on top of RDMA-capable high speed networks (such as SRP, ISER and NFSoRDMA). Next, an overview of different file systems (such as network file systems and parallel file systems) will be presented. Significance of the emerging RDMA techniques and their benefits in enhancing storage and file systems will be emphasized. Available networking storage products and the market trends will also be highlighted. Finally, case studies and performance evaluation involving lower-level software stacks (iSCSI, iSER/SRP with OpenIB and iWARP) and upper-level software stacks (Lustre, NFSoRDMA and GFS) will be presented. Targeted Audience: The tutorial is targeted for various categories of people (such as researchers, engineers, scientists, managers, and system developers) working in the areas of storage and file systems, high performance communication and I/O, and applications related to next generation high-end systems (such as clusters for storage systems, file systems, cluster-based servers (web, database), enterprise systems, etc.). Bios: Dhabaleswar K. (DK) Panda is a Professor of Computer Science at the Ohio State University. He obtained his Ph.D. in computer engineering from the University of Southern California. His research interests include parallel computer architecture, high performance computing, high performance networking, file systems, network-based computing, and Quality of Service. He has published over 195 papers in major journals and international conferences related to these research areas. Dr. Panda and his research group members have been doing extensive research on InfiniBand and the emerging iWARP. His research group is currently collaborating with National Laboratories and leading InfiniBand and iWARP companies on designing various subsystems of next generation High Performance Computing systems and file systems with InfiniBand and iWARP. The MVAPICH/MVAPICH2 package developed by his research group (http://nowlab.cse.ohio-state.edu/projects/mpi-iba/) is being used by more than 370 organizations world-wide (in 30 countries) to extract the potential of modern interconnects and protocols HPC applications. This software has enabled several InfiniBand clusters (including the 8000-processor Sandia Thunderbird Cluster) to get into the latest TOP500 ranking. It is also available with the OpenIB stack and the recently released Open Fabrics Enterprise Distribution (OFED) stack by InfiniBand vendors and Linux distros. Dr. Panda's research is supported by funding from US National Science Foundation, US Department of Energy, and several industry including Intel, Cisco, SUN, Mellanox, NetApp and Linux Networx. Weikuan Yu has recently earned his Ph.D. from Prof. Panda's group, and is now an R&D Staff Member of the Future Technology group at Oak Ridge National Laboratory. He also works for National Center for Computational Sciences (NCCS). Dr. Yu has carried out extensive research on various networking storage and file system protocols, including NFS, iSCSI, PVFS2, Lustre. He has worked as an intern at Los Alamos National Laboratory. Dr. Yu is a recipient of Outstanding Research Award of Excellence from Department of Computer Science and Engineering in 2005. He has published more than 17 papers in International conferences and journals.
