In my talk, I will present Conquest, a disk/persistent-RAM hybrid file system I designed and built at UCLA. Conquest provides a smooth transition of primary storage medium from disk to persistent RAM by combining the strengths of both storage media. The integration of the RAM component into the file system also leads to major architectural changes to low-level disk-tailored mechanisms, critical data paths, file system representation, and disk-related optimizations.
In terms of performance, Conquest realizes most of the benefits of persistent RAM at a fraction of the cost of pure RAM systems. Further, measurements show that Conquest achieves significantly faster performance than leading disk-based file systems under existing caching solutions.
