Title: On Fault Resilience of Data Storage

Abstract: One key enabler of modern data-driven innovation is the data storage systems that manage the massive scientific data. Such systems are also pervasive in daily life for keeping bank transactions, family photos, etc. Therefore, failures of data storage systems are extremely damaging — if your browser crashes you sigh, but when your family photos disappear you cry. In this talk, I will focus on the fault resilience of two representative types of storage systems: databases and distributed file systems. The first project analyzes the potential atomicity, consistency, isolation, and durability (ACID) violations in database transactions under faults, and the second project analyzes the failure recovery of large-scale storage nodes. I will provide concrete examples of vulnerabilities in the widely-used real-world systems which may lead to data corruption, resource leak, etc. Through the analysis, we can better understand the weakness of modern systems and help build computer systems that can guarantee data integrity. Moreover, we hope to raise the awareness of vulnerabilities in “mature” systems, and call for the community’s collective efforts in examining such an increasing challenge and coming up with scalable solutions.

Bio: Mai Zheng is an Assistant Professor in the Department of Computer Science at the New Mexico State University. His research spans from storage hardware to large-scale data management software, with a focus on system dependability. His work appears in venues such as OSDI, FAST, ASPLOS, ICS, PPoPP, as well as in the media including ZDNet, Slashdot, the RISKS Digest, etc. He is the PI of two NSF research grants and a senior personnel of several NSF education grants. Mai earned his bachelor’s degree from Qingdao University in 2006 and his master’s degree from University of Science and Technology of China in 2009, both in Electronic Science and Technology; he received his Ph.D. in Computer Science from The Ohio State University in 2015.
