  • Patent number: 7467276
    Abstract: A system and method automatically generates a root volume for use by a storage operating system of a storage system. During initialization of the storage system, the storage operating system detects that no operational root volume exists and, in response, invokes a root volume generation process. The root volume generation process automatically creates a thinly provisioned flexible volume of the smallest allowable size on an aggregate. The created flexible volume is marked as the root volume for the storage system. The storage operating system then continues initialization utilizing the automatically generated root volume.

  • Patent number: 7444361
    Abstract: A method for reducing duplicate data of an active file system, where the data is stored on a storage device of a storage system, is disclosed. A persistent image of the active file system is generated at a first point in time. At a later time, a sequence of steps to compare the active file system with the persistent image is initiated. Then, if a block of data of the active file system is identical to the data in the persistent image, the active file system is directed to refer to the persistent image for data of the file. Alternatively, if the block of data of the active file system is not identical to the data in the persistent image, the active file system is directed to refer to the data of the active file system. A file folding command may be issued to start the comparison.

  • Patent number: 7313720
    Abstract: An on-disk storage arrangement increases the number of persistent consistency point images (PCPIs) that may be maintained for a volume of a storage system. The on-disk storage arrangement comprises a novel volume information (volinfo) block representing a root of the volume; the volinfo block is stored at predefined locations on disk and comprises various system wide configuration data. The volinfo block further comprises a data structure configured to provide a level of indirection that increases the number of PCPIs maintainable by a file system executing on the storage system. To that end, the data structure may be organized as an array of pointers, wherein each pointer references a block containing a snapshot root, thereby enabling efficient access to each PCPI maintained by the file system.

  • Patent number: 7111021
    Abstract: A system and method for implementing on-the-fly block ownership accounting of snapshots in a file system is provided. For each snapshot, including the current active file system, the number of blocks that the snapshot is the youngest and oldest owner of is computed and stored in non-volatile storage. As file system operations modify the file system and associated snapshots, the youngest and oldest owner counts are updated concurrently with the execution of the file system operations, thereby providing near instantaneous access to the count information for use by various file system commands.

  • Patent number: 7072910
    Abstract: A file folding technique reduces the number of duplicate data blocks of a file consumed on a storage device of a file server configured to generate a persistent image of its active file system at a point in time. According to the file folding technique, if “old” data blocks of the file are over-written with “new” data and that new data is identical to the data of the persistent file image, the old data blocks are “freed” and the file is directed to refer to the persistent image for its data. The invention reduces disk space consumption in a file server configured to generate persistent images of its active file system and, in particular, reduces overall persistent image disk usage.

  • Patent number: 7051050
    Abstract: The present invention provides a system and method for restoring a single file from a snapshot without the need to copy every individual block or inode from the snapshot. A file restore process duplicates the inode of a file within the active file system and performs a reconciliation process between the blocks of the twin inode and the snapshot inode. If the file does not exist within the active file system, a new buffer tree is created that points to the data blocks stored in the snapshot.

  • Patent number: 6692051
    Abstract: Provided herein is a cab for a tractor-truck. The cab includes a work station, suitable for use as a desk or the like, which can be provided with common office machines. Also provided in the cab is a seat, which is slidably fixed to a seat-supporting track that extends across the floor of the cab, so that the seat can be selectively positioned between a driving position and a workstation position. The tractor-truck can be equipped with an interlock system that keeps the vehicle from moving if the seat is not in the driving position. Also, when the seat is not in the workstation position, a second seat can be detachably fixed in the workstation position.

  • Patent number: 6385546
    Abstract: The invention described herein is a method of identifying and changing amino acid residues that affect the stability of a protein and thereby to “adjust” the stability of a protein under particular conditions, e.g., to function at lower or higher temperatures. The residues modified in the method are chosen such that they are not in or interact with an active site or binding site of the protein, and therefore the mode of action or interaction of the protein on substrates remains unchanged. The method has wide applicability to any situation where a protein would be a better match to a pre-existing or new process if the functional optimum of the protein under particular conditions were different. Among others, the method is useful to produce proteins for bioremediation, food technology and enzymes for detergents.
