VIRTUAL FILE SYSTEM SUPPORTING MULTI -TIERED STORAGE

摘要

A plurality of computing devices are interconnected via a local area network and comprise circuitry configured to implement a virtual file system comprising one or more instances of a virtual file system front end and one or more instances of a virtual file system back end. Each instance of the virtual file system front end may be configured to receive a file system call from a file system driver residing on the plurality of computing devices, and determine which of the one or more instances of the virtual file system back end is responsible for servicing the file system call. Each instance of the virtual file system back end may be configured to receive a file system call from the one or more instances of the virtual file system front end, and update file system metadata for data affected by the servicing of the file system call.
