ABSTRACT
A large-scale deployment of flash devices into data centers can greatly improve the overall system performance and reduce the rapidly growing management cost (e.g., power, cooling, staffing, floor space). Despite the technical merits promised, such a grand technical transition fundamentally changes the long-held system design assumption for a disk-based storage and will inevitably bring major critical challenges in a real-world practice. For example, underutilization of flash space would cause huge economic loss; premature device wear-out may result in catastrophic data corruption; unbalanced system could bring severe resource contention; unoptimized applications may not receive anticipated benefits; and many others.
This project aims to address these challenges. Research will be conducted to develop a cohesive design approach to providing an orchestrated whole-system optimization. By revisiting the entire storage hierarchy, from hardware, operating system, cluster middleware, to applications, the team will redesign the device architecture to enable an organic integration of flash devices as integral elements in a huge flash storage system, create a flash-based distributed storage service with optimized resource utilization and guaranteed data reliability. Furthermore, a set of key data center applications will be enhanced to fully exploit the great potential of the flash technology. As part of this CAREER project, the team will also seek influence to the industry, contribution to curriculum, and outreach to local area under represented students.

PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
This project aims to develop solutions to address the emerging challenges in the process of adopting flash storage technologies in data center environments. Many important technical issues must be addressed to achieve this goal. We have extensively investigated the involved research problems and developed effective solutions to optimize the system and application designs for flash storage in data centers.
In this project, we have systematically studied the fundamental issues with integrating flash storage in data center systems. Modern flash storage technologies have many technical merits. However, transitioning the existing systems and applications from traditional disk-based storage to flash storage poses many new challenges, which we must address for fully exploiting its performance potential while mitigating its technical constraints. We have investigated these critical challenges and developed a set of novel solutions for flash-optimized systems and applications in data center environments. These new designs and methods have been comprehensively studied and evaluated. Our research results are reported in peer-reviewed papers published in renowned journals and conferences, which provide a solid foundation for the community to effectively adopt this new technology and maximize its efficacy.
This project has also made broader impacts in multiple aspects. A variety of training opportunities have been created for students at different levels. Throughout this project, four Ph.D. students have been involved in research work. Two of them have graduated with a Ph.D. degree and are currently serving in the industry. A set of new teaching methods and research-oriented components have been developed and adopted by the PI in multiple computer science courses, which brings benefit to many students with diverse backgrounds. By participating in various activities in the local community, the PI has also introduced academic research and extended the scope of its impact to the general public.
