NOVA is high-performance, full-featured, fault-tolerant file system tailored for byte-addressable non-volatile memories (e.g., NVDIMMs and Intel’s soon-to-be-released 3D-Xpoint DIMMs). It combines design elements from many other file systems to provide a combination of high-performance, strong consistency guarantees, and comprehensive data protection. NOVA support DAX-style mmap and making DAX performs well is a first-order priority in NOVA’s design.
NOVA is open-source, you can try it yourself. You can also read more about it on Wikipedia or in the papers below.
