    摘要: A method to encode information holographically, wherein the method provides information, and generates a plurality of data images, wherein each data image comprises a portion of the information. The method holographically encodes each of the plurality of data images in a holographic data storage medium, generates a plurality of identifiers, and associates a different one of the plurality of identifiers with a different one of the plurality of data images. The method forms a directory image reciting each of plurality of identifiers, encodes the directory image in a non-holographic data storage medium, and holographically encodes the directory image in the holographic data storage medium.

    摘要: A method to allocate resources in a data storage library comprising a plurality of data storage devices configured as a RAID array, by establishing a normal operation resource allocation, a RAID failure resource allocation, and a multiple storage device failure resource allocation. The method receives host I/O requests, and enqueues those host I/O requests. If the system is operating without any storage device failures, then the method processes host I/O requests using the normal operation resource allocation. If the system is operating with a storage device failure, then the method processes host I/O requests using the RAID failure resource allocation. If the system is operating with multiple storage device failures, then the method processes host I/O requests using the multiple storage device failure resource allocation.

    摘要: A method is disclosed to store information in a holographic data storage medium. The method supplies a holographic data storage medium and provides information. The method defines an Active storage portion for the holographic data storage medium and establishes a threshold access interval. The method determines if the information was last accessed within the threshold access interval. If the information was last accessed within said threshold access interval, the method then stores that information as one or more holograms encoded in said Active storage portion of the holographic data storage medium.

    摘要: Data for storage by holographic data storage is arranged in an intermediate data storage as data segments which are replicas of holographic storage segments. Files of data are aggregated into the data segments, and a destaging control determines the destaging of the data segments to the holographic data storage in accordance with a plurality of policies, such as whether a segment is full, a time threshold has been reached, or whether a threshold number of segments are “open”. The intermediate data storage may be arranged into a number of partitions at least equal to the number of sources having input to the data destaging system, the partitions comprising integral multiples of the data segments.

    摘要: Data that is to be deduplicated and compressed is received. The data is compressed then deduplicated to generate first compressed then deduplicated data. The data is deduplicated then compressed to generate first deduplicated then compressed data. The first compressed then deduplicated data is stored if the first compressed then deduplicated data is smaller in size than the first deduplicated then compressed data. The first deduplicated then compressed data is stored if the first deduplicated then compressed data is smaller in size than the first compressed then deduplicated data.

    摘要: A method is disclosed to store and retrieve information using holographic data storage media. The method provides original data, generates a first image of that original data, and encodes that first image in a holographic data storage medium at a first storage location. The method then generates a second image of the original data, where the second image differs from the first image, and encodes the second image in a holographic data storage medium at a second storage location, where the second storage location differs from the first storage location.
