Abstract:
Techniques are described herein that are capable of heterogeneously optimizing a file. Heterogeneous optimization involves optimizing regions of a file non-uniformly. For example, the regions of the file may be optimized to different extents. In accordance with this example, a different optimization technique may be used to optimize each region or subset of the regions. In one aspect, optimization designations are assigned to respective regions of a file based on access patterns that are associated with the respective regions. The file may be a database file, a virtualized storage file, or other suitable type of file. Each optimization designation indicates an extent to which the respective region is to be optimized. Each region may be optimized to the extent that is indicated by the respective optimization designation that is assigned to that region.
Abstract:
A linear cable laying engine has a pair of endless belts (12,14) having a substantial length (16,18) in respective face to face opposition, and means for applying force to the belts to cause them to grip a cable (42) between the opposed faces.
Abstract:
A heat extracting substrate is moved along a melt front formed at the edge of the surface of a molten material so that a layer of molten material is deposited on the substrate, cooled and removed from the substrate to form ribbon, filaments, fiber of film directly from the molten material. The edge may be formed by providing an upper edge upon a portion of the wall of a receptacle lower than the top of the receptacle. The molten material may be overflowed over this relatively horizontal edge and against the moving substrate surface.
Abstract:
The present invention relates to a method of manufacturing widgets from components and/or particulate; and to a can for containing such components and/or particulate during the consolidation into widgets. The method of the present invention can be used to form widgets from metals, ceramics, plastics, polymers, and/or combinations thereof. The materials used to form the widgets can be in the form of particulate, pellets, shard, and/or ribbon. The method of the present invention can also be used to join widgets and/or to heal ingot cracks.

Abstract:
Techniques for backup and restore of optimized data streams are described. A chunk store includes each optimized data stream as a plurality of chunks including at least one data chunk and corresponding optimized stream metadata. The chunk store includes data chunks in a deduplicated manner. Optimized data streams stored in the chunk store are identified for backup. At least a portion of the chunk store is stored in backup storage according to an optimized backup technique, an un-optimized backup technique, an item level backup technique, or a data chunk identifier backup technique. Optimized data streams stored in the backup storage may be restored. A file reconstructor includes a callback module that generates calls to a restore application to request optimized stream metadata and any referenced data chunks from the backup storage. The file reconstructor reconstructs the data streams from the referenced data chunks.
Abstract:
Techniques are described herein that are capable of optimizing (i.e., deduplicating) data in a virtualization environment. For example, optimization designations (a.k.a. deduplication designations) may be assigned to respective regions of a virtualized storage file. A virtualized storage file is a file that is configured to be mounted as a disk or a volume to provide a file system interface for accessing hosted files. In accordance with this example, each optimization designation indicates an extent to which the respective region is to be optimized (i.e., deduplicated). In another example, a virtualized storage file is mounted to provide a virtual disk that includes hosted files. In accordance with this example, optimization designations are assigned to the respective hosted files. In further accordance with this example, each optimization designation indicates an extent to which the respective hosted file is to be optimized.
