Welcome!

I am Baoquan Zhang, a PhD Candidate (Sep.2015 - current) in Computer Science at University of Minnesota Twin-Cities advised by Professor David H.C. Du. Currently, I am a member of CRIS (Center for Research in Intelligent Storage), UMN and working on Cloud Storage, Software RAID Systems, SMR Drives, Key-Value Stores and etc.

Before joining UMN, I got B.E. (Sep. 2008 - July 2012) and M.S. (Sep. 2012 - April 2015) degrees in Computer Science & Technology at Harbin Engineering University, China. As a Research Assistant (June 2013 - April 2015), I worked in Cloud Storage in the storage systems group at Research Institute of Information Technology, Tsinghua University, Beijing advised by Prof. Dongsheng Wang.

Research Experience

University of Minnesota - Twin Cities
Twin Cities, Sept. 2015 ~ Present
SMRMD: a design of Software RAID 5/6 on Host-Aware SMR drives

Design a software RAID 5/6 on Host-Aware SMR drives to mitigate the performance degradations caused by the drive cleanings.

Improving data integrity in Linux Software RAID 5/6 using T10 PI

Design and implement a DIX-aware MD module using T10 PI to solve the integrity losing problem of current MD module in Linux kernel.

Tsinghua University
Beijing, June 2013 ~ April 2015
Construction of big data management systems supporting both OLAP and OLTP

A hybrid system combining relational databases with applications of big structured data processing was designed to construct a general platform supporting both OLAP and OLTP.

Research of I/O scheduling in distributed systems for data-intensive computing

A mathematical model which scheduled the I/O requests among nodes according to their performance was established to improve the system performance by balancing the time cost among nodes.

Research of data joining for geo-distributed clouds

Designed and implemented a method based on a cache mechanism to improve the performance of data joining among geo-distributed Hadoop clouds.
