Making large-scale storage systems dependable against failures is critical yet non-trivial in the face of the ever-increasing amount of data. In this talk, I will present new theoretical and applied findings on erasure coding, a low-cost redundancy technique for fault-tolerant storage. I will first present general techniques and code constructions for accelerating the repair of storage failures, and further propose a unified framework for readily deploying a variety of erasure coding solutions in state-of-the-art distributed storage systems.  I will also introduce my recent work on wide stripes and the repair parallelization of optimal erasure codes.


Patrick P. C. Lee is now a Professor in the Department of Computer Science and Engineering at the Chinese University of Hong Kong. His research interests are in various applied/systems topics on improving the dependability of storage systems, distributed systems, and networks.  He has been serving as an Associate Editor in IEEE/ACM Transactions on Networking and ACM Transactions on Storage, as a TPC co-chair of APSys 2020, LANMAN 2022, and DSN 2025, and as a TPC member of several major systems and networking conferences.
