Abstract: 

Persistent Memory (PM)-based file systems are key to bringing the low-latency value of PM hardware to applications and businesses. But developing a portable POSIX-compliant file system using the traditional Kernel-to-user space FUSE bridge results in high-latency access, and thus defeats the purpose. To bridge this gap NetApp has developed the open source ZUFS bridge. ZUFS was designed with PM latencies and byte addressability in mind. It enabled NetApp PM-based solution to be more portable and is allowing the open source community to develop a new breed of efficient PM file systems in user space.
