NSF Supports Tseng’s Research on SSD Efficiency

Dr. Hung-Wei Tseng, assistant professor of computer science at NC State University, has been awarded $174,998 by the National Science Foundation (NSF) to support his research proposal entitled “Rethinking the FTL in SSDs – a File Translation Layer Instead of a Flash Translation Layer.” 
The award will run from March 15, 2017 to February 28, 2019.
Abstract – SSDs (solid state drives) nowadays become popular in all kinds of computing systems. However, these systems still leverage the existing block interface to manage SSDs, resulting in multiple layers of indirections, under-utilized parallelism inside the SSD, overheads for in-storage computing, and difficulties in sharing files among heterogeneous computing devices.

This work will reshape the current system stack and simplifies the software/hardware interface for SSDs by using the SSD to directly map files into physical block addresses on the SSD. This work will demonstrate the effect of the proposed system in applications ranging from file systems, datacenter storage, and virtualized machines.
