Research Status
Research fields in my group include: non-volatile memory (NVM) systems and technologies, network (/cloud/big data) storage systems and technologies, and storage reliability and security, etc.
In the aspect of NVM systems and technologies, to address the problems of both the inability of legacy storage architecture and software systems (which are designed for hard disks) in exploiting the advantages of NVMs and the limitations of NVM on performance and endurance, we have performed research on NVM system building and the related technologies; In response to a series of problems and challenges in building persistent memory storage systems, such as NVM device abstraction, consistency guarantee during system failure, memory fragmentation, operating system abstraction and software overhead, we have performed in-depth research in the programming model of persistent memory, data structure, space management, (distributed) persistent memory file system, reliability, processing in memory (PIM) architecture and technologies. Main results are published in international conferences (including OSDI’2021, FAST’2021(2), ASPLOS’2020, MICRO’2018/2014, USENIX ATC’2021/2017(2), EuroSys’2019/2016, ICDE’2021, VLDB’2020, ISCA’2015, DAC’2019/2016/2015, DSN’2014, MSST’2020/2016/2015(Best Paper Nomination), ICCD’2014, DATE’2017(2), ICPP’2016, CF’2015, GLSVLSI’16, ASP-DAC’2018/2016, NVMSA’2019/2018/2016/2015, et. al.) and journals (including ACM TOS 2020/2019/2018/2016, IEEE TPDS 2019). Based on the above key technologies, we have developed TH-DPMS (a distributed persistent memory storage system), KucoFS (a persistent memory file system), ScaleRPC (a scalable RDMA network system), and Octopus (a distributed persistent memory file system). These systems and their application have won Huawei’s first "Olympus Award" and the One Million Award in 2020, and the First Prize of Science and Technology Award of China Computer Federation for Technology Invention in 2020.
In the aspect of solid storage system and technology based on Flash devices, in response to the contradiction between flash memory device architecture and flash memory characteristics and disk-centric storage architecture and software design, which leads to a series of serious problems such as functional redundancy, perception shielding, semantic isolation, and system performance jitter, we have proposed an open-channel flash memory storage architecture with direct management of the software, which is supported by the Linux4.4 kernel and subsequent versions. Main results are published in international conferences (including OSDI’20, FAST’2014/2013, USENIX’2016, SC’2017, DAC’2020/2019, ICDCS’2020/2019, IPDPS’2014, ICCD’2013, DATE’2014, CODES+ISSS’2017, NVMSA’ 2014 et al.) and journals (including ACM TOS 2019、IEEE TC 2019/2016/2015、IEEE TPDS 2018). we have developed a flash storage system named TH-SSS, and mainly studies solid-state storage and related technologies based on open-channel SSDs, including flash-based file system ParaFS, flash-based key-value storage system FlashKV, distributed flash storage system OCStore, etc. These systems and their applications won the first prize of the Science and Technology Invention Award of the Ministry of Education in 2019; part of the results have been transferred and applied to relevant partner companies.
In the aspect of network (/cloud/big data) storage systems and technologies, to address the problems of performance, scalability, compatibility, ease of use, security, and manageability of large-scale storage systems, we have performed research on storage virtualization, online scaling, metadata management, cache strategies, hierarchical storage, parallel SAN file system and secure cloud system. We have also developed a SAN-based network storage system, TH-MSNS (Tsinghua Mass Storage Network System). At present, there are nearly 100 sets of TH-MSNS applied in many fields, including audit, public security, oil field, telecom, and education. Main results are published in international journals (including IEEE TOC 2016/2014/2010/2007/2005、ACM TOS 2010/2007, IEEE TPDS 2016/2015/2014, JPDC 2018/2014, et. al.) and conferences (including IPDPS’2016, CODES/ISSS’2016, IWQos’2014/2013, ICPP’2012, CLUSTER’2012, MSST’2006, et. al.).
In the aspect of data reliability in storage systems, to address the problems of fault tolerance capacity (i.e., single fault tolerance, double fault tolerance, and multi-fault tolerance), performance (i.e., coding efficiency), and storage utilization of erasure codes, we have proposed and implemented several high-performance and practical techniques of erasure codes. Main results are published in international conferences (including USENIX ATC’2021, DSN’2016/2014, SRDS’2020/2017/2016/2015/2014, IPDPS’2020/2015, ICPP’2015/2013/2012, et. al.) and journals (including IEEE TC 2017/2016/2010, IEEE TPDS 2019/2018/2017/2016, IEEE TDSC 2020, ACM TOS 2012/2009, et. al.).
