Abstract: Systems and techniques relating to network file systems are described. A described technique includes associating with a process that exports a network file system, where the process manages the network file system, associating with one or more peers that use the network file system, where the one or more peers cache data associated with the network file system on one or more non-volatile memory structures, receiving a file system request to read or write at least a portion of a file that is associated with the network file system, and processing the file system request by selectively communicating with the one or more peers to retrieve cached data associated with the file when the file system request indicates a read or inform the one or more peers of a write to the file when the file system request indicates a write.

Abstract: Apparatuses, methods, and other embodiments associated with distributed metadata caching are described. According to one embodiment, a method includes intercepting a metadata request intended for an NFS server and communicating with a member of the set of peers to satisfy the metadata request from a distributed metadata cache maintained by the set of peers. The metadata request will have originated from a member of a set of peers participating in peer-to-peer distributed metadata caching.
