The Spring File System cache coherent file data and attributes. It uses the virtual memory system to provide data caching and uses the operations provided by the virtual memory system to keep the data coherent. The file system consists of two types of file servers: ones that provide coherent access to files they export and ones that run on each Spring machine and provide caching of data and attributes for remote files. The per-machine caching file server utilizes the virtual memory system to provide caching of data for read and write operations, and has its own private protocol with the remote file servers to cache file attributes.
