Andiry described building the world’s first fault-tolerant non-volatile main memory file system at SOSP’17 in Shanghai. The resulting file system — NOVA-fortis — provides a mechanism to take consistent snapshots to facilitate backups and protects both metadata and file data from media and software errors. Here’s the full paper.
While he was on the continent, Andiry is also presenting NOVA at Tsinghua University, Wuhan university, and Huazhong University of Science and Technology.
Well done, NOVA hackers!
