Abstract: Apparatus includes a file server node having (i) a first interface operable to communicate with a network and receiving a network request via network, (ii) a non-volatile memory operable to temporarily store a request related to the network request received by the first interface, (iii) a second interface operable to be coupled to the storage device for storing the request, and (iv) a non-volatile memory processing module, coupled to the first interface, the non-volatile memory and the second interface, and operable to be coupled to another file server node, so that the request can be sent to the non-volatile memory, the second interface and the another file server node after the non-volatile memory processing module receives the file system request.

Abstract: Apparatus for managing a plurality of root nodes may include a file server coupled to a storage device, wherein a first root node is operable to identify a previous version of an object of a file system and to relate to a plurality of data blocks forming a portion of the object, a second root node is operable to identify a current version of the object and to relate to a data block of the plurality of data blocks and a new data block of the object, and the storage device is operable to store the plurality of data blocks and the new data block. Apparatus for managing a plurality of root nodes alternatively may include a file system board operable to manage a plurality of root nodes, a first root node being operable to identify the a previous version of a file system and to relate to a plurality of data blocks of the file system, and a second root node being operable to identify the a current version of the file system and to relate to a data block of the plurality of data blocks and a new data block of the file system.
