    摘要: A method for performing parallel data indexing within a data storage system is disclosed. After the receipt of a group of data objects, the data objects are copied to an indexing module. Next, the copy of data objects within the indexing module are indexed by the indexing module while the data objects are being stored within a storage medium. The indices of the copy of data objects within the indexing module are stored in an index repository within the indexing module.

    摘要: A rotary switch rotates about an axis which is at acute angles to a lower cartridge surface and a cartridge end so that a first display surface and a second display surface may be independently accessed by disparate components residing in disparate planes. The display surfaces are generally orthogonal to each other and can have multiple facets, with each facet containing a subset of information. To aid this optical interrogation, the display surfaces may be generally orthogonal to the disparate interrogating components.

    摘要: An apparatus, system, and method are disclosed for hard disk drive redundancy. A demarcation module demarks a parity data block in each set of a specified number of data blocks on a hard disk drive. An association module associates a PBA of each un-demarked data block with a LBA. A write module writes the data to the un-demarked data blocks. A parity module calculates parity data for the data written to the un-demarked data blocks and the write module writes the parity data to the parity data block.

    摘要: A dual-path optical recording medium and an apparatus for accessing such are disclosed. The dual-path optical recording medium includes a substrate, an intermediate recording layer, a holographic recording layer and a dichronic mirror layer. The intermediate recording layer is a rewritable data storage layer with a relatively low storage capacity. The holographic recording layer is a write-once data storage layer with a relatively high storage capacity. The dichronic mirror layer is located between the holographic recording layer and the intermediate recording layer. The apparatus for accessing the dual-path optical recording medium includes a first light module capable of generating a first laser light, and a second light module capable of generating a second laser light.

    摘要: A velocity calculator performs high-order calculations of servo frame velocities of a storage media, particularly tape and disk. The velocity calculator employs a servo frame indexing module for generating a first-order preceding servo frame velocity signal indicative of a first-order calculation of a preceding servo frame velocity including a first-order preceding servo frame error term based on first-order current servo frame velocity signal indicative of a first-order calculation of a current servo frame velocity including a first-order current servo frame error term. The velocity calculator further employs a velocity estimating module for generating a higher-order current servo frame velocity signal indicative of a second or higher order velocity calculation of the current servo frame velocity including a higher-order current servo frame error term based on the first-order preceding servo frame velocity signal and the first-order current servo frame velocity signal.

    摘要: A Redundant Array of Independent Devices uses convolution encoding to provide redundancy of the striped data written to the devices. No parity is utilized in the convolution encoding process. Trellis decoding is used for both reading the data from the RAID and for rebuilding missing encoded data from one or more failed devices, based on a minimal, and preferably zero, Hamming distance for selecting the connected path through the trellis diagram.

    摘要: A mechanism is provided for optimizing migration/copying of de-duplicated data from an internal storage system to a removable storage system. A preliminary number of clusters to be generated are determined for sets of data objects stored on the internal storage system based on a number of the sets of data objects. The preliminary number of clusters is generated based on shortest distances between the sets of data objects, each cluster comprising one or more sets of data objects and each set of data objects comprising one or more chunks of data. A chosen cluster is identified from a set of clusters by identifying a cluster having a greatest number of common chunks within as few sets of data objects. Responsive to an export-size of the chosen cluster failing to exceed the available storage capacity of the removable storage system, the chosen cluster is exported to the removable storage system.
