    摘要: A storage unit coupled to a controller for receiving a first control signal and a second control signal is provided. The storage unit includes a cell array, a first access module and a second access module. The cell array stores data. The first access module accesses the data stored in the cell array according to the first control signal. The second access module processes the data stored in the cell array according to the second control signal to generate a search result and provides the search result to the controller. When the first access module receives the first control signal and the second access module receives the second control signal, the first and second access modules simultaneously operate.

    摘要: An adaptive guard band for a ramp load/unload device is disclosed to provide extended data storage. In illustrated embodiments, an adaptive guard band algorithm is configured to format one or more discs or media having a lower capacity device with the adaptive guard band and extended data zone utilizing capacity measurements. The algorithm formats the media to provide a track zero at a first cylinder if the capacity is at or above the threshold capacity and a second cylinder if the capacity is below the threshold capacity to provide the extended data storage zone. A size or width of the extended data zone is variable to provide additional capacity to meet the threshold capacity.

    摘要: A system for real-time operating system memory block and message management is disclosed. The real-time operating system enables different processes to migrate an allocated memory block from one type of memory block to another type of memory block, and to reliably release the block back to its correct pool of origin. According to one aspect of the inventive subject matter, a memory management engine allocates memory in a basic type to a first process, and upon a migration request from a second process, convert the allocated memory from the basic type to a message type for the second process. Allocating memory in the basic type can be fast but does not ensure proper release of the memory block to its pool of origin. Converting the basic type to the message type enables the operating system to reliably release the block back to its correct pool of origin from any process.

    摘要: For adaptive similarity search resolution in a data deduplication system using a processor device in a computing environment, multiple resolution levels are configured for a similarity search. Input similarity elements are calculated in one resolution level for a chunk of input data. The input similarity elements of the one resolution level are used to find similar data in a repository of data where similarity elements of the stored similar repository data are of the multiple resolution levels.

    摘要: Method, data processing systems, and computer program products are provided for virtualizing and managing a storage virtualization system (SVS) in a storage management architecture. Source data is copied from the source storage media to target data in a target storage media based on a predefined copy policy in a copy mapping table. A relation between the source data and the target data is tracked in a copy mapping table. It is determined if a copy of the requested data exists using the copy mapping table. Tiered storage policies are configured in a migration mapping table pertaining to the SVS. A source storage media is mapped to a target storage media and a migration policy. Responsive to the migration policy condition, determining the source storage media and a migration storage media. A copy relation between source storage media and migration storage media is determined to exists using the copy mapping table.

    摘要: A RAID system is provided in which, in the event that a rebuild is to be performed for one of the PDs, a filter driver of the operating system of the computer of the RAID system informs the RAID controller of the RAID system of addresses in the virtual memory that are unused. Unused virtual memory addresses are those which have never been written by the OS as well as those which have been written by the OS and subsequently freed by the OS. The RAID controller translates the unused virtual memory addresses into unused physical addresses. The RAID controller then reconstructs data and parity only for the unused physical addresses in the PD for which the rebuild is being performed. This reduces the amount of data and parity that are rebuilt during a rebuild process and reduces the amount of time that is required to perform the rebuild process. In addition, the RAID system is capable of being configured to prevent or reduce data sprawl.

    摘要: In a nonvolatile memory array, such as a three-dimensional array of charge-storage memory cells, data is randomized so that data of different strings along the same bit line are randomized using different keys and portions of data along neighboring word lines are randomized using different keys. Keys may be rotated so that data of a particular word line is randomized according to different keys in different strings.
