    摘要: A hardware-based file system includes multiple linked sub-modules that perform functions ancillary to client data handling. Each sub-module is associated with a metadata cache. A doubly-rooted structure is used to store each file system object at successive checkpoints. Metadata is stored within an object and/or as a separate object. Provisions are made for allocating sparse objects. A delayed write feature is used for writing certain objects into non-volatile storage. Checkpoints can be retained as read-only versions of the file system. Modifications to the file system are accomplished without affecting the contents of retained checkpoints. The file system can be reverted to a retained checkpoint. Multiple file servers can be interconnected as a cluster, and each file server stores requests from another file server. Interconnections between file servers can be dynamically modified. A distributed locking mechanism is used to control access to file system objects stored by the file servers.

    摘要: Methods and apparatus automatically identify certain types of data storage system problems, such as a flawed storage device or an incompatibility between a data storage system and a data storage device or an incompatibility between the storage system and a user computer. The existence of such a problem may be highlighted to a user through an indicator on the storage system and/or through a “dashboard” application being executed by the user computer, and the problem may be automatically corrected by automatically downloading a fix (e.g., new firmware or a “patch”) from a server (e.g., a server managed by the storage device manufacturer, a server managed by the storage system manufacturer and/or a server managed by a third party) and automatically implementing the fix.
