摘要:
A data storage cartridge comprises data storage media configured to store data for read and/or write access, wherein the data may be arranged in a plurality of partitions; and a plurality of cartridge memories. A control system, for example of a data storage drive, is configured to allocate at least portions of capacity of the data storage media to cartridge memories of the data storage cartridge; and to provide information defining the allocated portions of capacity to the cartridge memories. Each of the cartridge memories may have a separate user and thus provide access for that user to separate partitions.

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.

A portable data storage assembly, comprising a holographic data storage layer, and an optical tracking layer comprising addressing information for the holographic data storage layer, wherein that addressing information defines a first storage band comprising a first plurality of storage addresses and a second storage band comprising a second plurality of storage addresses, wherein said second plurality of storage address is greater than said first plurality of storage addresses.

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 to access a data in a RAID array comprising a plurality of data storage media, wherein information is written to said plurality of data storage media using a RAID configuration, wherein the method receives from a requester a command comprising a data access priority indicator. If a RAID rebuild is in progress, the method determines if the data access priority indicator is set. If the data access priority indicator is set, the method executes a command selected from the group consisting of writing information to the target logical block array range, and returning to the requestor information read from the target logical block array range.
摘要:
An apparatus, system, and method are disclosed for converting between serial data and encoded holographic data. The apparatus for converting between serial data and encoded holographic data is provided with a logic unit containing a plurality of modules configured to functionally execute the necessary steps of reading data signals from and writing data signals to a data bus on a computing device, converting between a serial data stream and an encoded data image, and reading data from and writing data to a holographic storage medium. From the foregoing discussion, it should be apparent that a need exists for an apparatus, system, and method for converting between serial data and encoded holographic data. Beneficially, such an apparatus, system, and method would encode backup information directly with the data as it is written to the storage medium.

Data hologram recycling systems, methods and computer program products are configured to arrange data for storage in the intermediate data storage as data segments which are replicas of holographic storage segments for destaging to the holographic data storage, and to determine retrieval for recycling of the destaged holographic storage segments to which aggregated requests for deletion are directed. The retrieval determination may be based on a plurality of policies.

A method and a system are provided for displaying information on a hard disk drive assembly. The hard disk drive assembly includes a hard disk drive which further comprises a driver circuit coupled to a display and a display memory. The driver circuit activates the display mounted on the hard disk drive assembly. In response to the activation of the display the driver circuit obtains information from the display memory of the hard disk drive. The driver circuit displays at least a portion of the information obtained from the display memory on the display mounted on the hard disk drive assembly.
