Abstract:
Today, with many exciting applications like cloud computing, digital twins, and AI&ML, the amount of data to be generated and stored has gone beyond the storage capability provided. This triggers us to re-think the design and develop of existing and future storage systems. In this talk, we will briefly exam the efforts from storage industry to develop new types of storage devices and how these devices to be put together to form a new generation of storage systems. How can some data be preserved for hundreds of years? The traditional research on storage systems focused on the trade-offs between higher performance and large capacity. Today, we also must consider the power management and sustainability. We will discuss a proposed storage system with SSD (Solid State Drives) plus a system called MAID (Massively Array of Idle Disks) based on hard drives which can potential address all the three objectives. Especially, we would like to consider both operational and embodied carbon emissions together. Operational carbon emission can be reduced by effective power management, but embodied carbon emission, including the carbon produced by manufacturing the device (material extraction, chip fabrication and package), transport and disposal of the device, can only be addressed by prolonging the lifetime of a device. We will also cover the research issue of how to prolong the lifetime of an SSD.
Biography:
David H.C. Du (杜宏章)– received his B.S. from National Tsing-Hua University in 1974 and the M.S. and Ph.D. degrees in computer science from the University of Washington, Seattle, in 1980 and 1981, respectively. He is currently the Qwest Chair Professor at the Computer Science and Engineering Department, University of Minnesota, Minneapolis and was the Director of NSF I/UCRC Center Research in Intelligent Storage from 2009 to 2021. He is an IEEE Fellow and a Fellow of Minnesota Supercomputing Institute. He served as a Program Director at National Science Foundation CISE/CNS Division from March 2006 to August 2008. At NSF, he was responsible for the NeTS (Networking Research cluster) NOSS (Networks of Sensor Systems) Program and worked with two other colleagues on Cyber Trust (Internet Security) Program. He has done research in cyber security, sensor networks, multimedia computing, storage systems, high-speed networking, high-performance computing, and database design and CAD for VLSI circuits. His current research focuses on storage technologies/systems and vehicular networks. He has authored and co-authored more than 350 technical papers. He has also graduated 68 Ph.D. and 100+ M.S. students in the past.
