    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: Apparatus for managing plural versions of a root node for an object of a file system manages an update data of a first version of the plural versions of the root node in a status in which (i) data of a second version of the plural versions of the root node is written from the second storage of the file server to the first storage and (ii) a new checkpoint, capable of being used when the object of the file system is recovered, is taken. The apparatus also manages an update data of the second version of the plural versions of the root node in another status in which (iii) data of the first version of the plural versions of the root node is written from the second storage of the file server to the first storage and (iv) a next new checkpoint is taken.
