Learn about the current development status and real-world applications of Famfs (Fabric-Attached Memory File System) in this 15-minute conference talk from the Linux Plumbers Conference. Discover how Famfs formats device memory into scale-out file systems, enabling access to multi-terabyte memory objects as files with POSIX permissions. Explore the progress toward upstreaming Famfs while understanding the challenges posed by recent DAX subsystem refactoring, as this pioneering file system becomes the first to be fully hosted on devdax (character dax). Examine the current deployment of Famfs in data-intensive workloads requiring in-memory performance across global implementations. Gain insights into the upstreaming roadmap, file-system-level memory interleaving capabilities, ongoing DAX issues and roadblocks, composable memory perspectives, and key use cases driving adoption of this innovative memory file system technology.
