    摘要： A self-healing Hard Disk Drive (HDD) system includes a chassis housing an HDD device self-healing subsystem coupled to an HDD data storage system that includes a plurality of HDD data storage resources. The HDD device self-healing subsystem prevents data from being stored on a first HDD data storage resource that is included in the plurality of HDD data storage resources included in the HDD data storage system. When the HDD device self-healing subsystem determines that data storage operations using a second HDD data storage resource that is included in the plurality of HDD data storage resources will be subsequently unavailable, it remaps logical addresses associated with the second HDD data storage resource to the first HDD data storage resource, and provides the data that was stored using the second HDD data storage resource on the first HDD data storage resource.

    摘要： Systems, apparatuses, and methods related to a memory array data structure for posit operations are described. Universal number (unum) bit strings, such as posit bit string operands and posit bit strings representing results of arithmetic and/or logical operations performed using the posit bit string operands may be stored in a memory array. Circuitry deployed in a memory device may access the memory array to retrieve the unum bit string operands and/or the results of the arithmetic and/or logical operations performed using the unum bit string operands from the memory array. For instance, an arithmetic operation and/or a logical operation may be performed using a first unum bit string stored in the memory array and a second unum bit string stored in the memory array. The result of the arithmetic operation and/or the logical operation may be stored in the memory array and subsequently retrieved.

    摘要： The storage system is a storage system comprising a plurality of storage nodes each including a non-volatile storage device, a storage controller that processes data read/write to the storage device, and a volatile memory, in which the storage controller stores data related to the data write in the memory, stores data that needs to be non-volatile among the data stored in the memory as log data in the storage device, makes the log data stored in the storage device redundant among a plurality of storage nodes, and performs a recovery process for the log data when a problem occurs in the log data stored in the storage device of one of the storage nodes.

    摘要： A method comprises selecting a sample excerpt from a data input file; in response to the determining that a first row in the sample excerpt does not contain a delimited value and a second row does contain a delimited value, determining that the first row consists of header data; identifying one or more jagged rows based on row delimiters that were erroneously placed; causing displaying text that led to creation of a jagged row; receiving an addition or removal of a specific row delimiter to the text; updating the sample excerpt based on the addition or the removal; analyzing the sample excerpt to determine a row delimiter for the data input file; identifying a plurality of rows that is not included in the header data; identifying a plurality of candidate column delimiters and generating a candidate schema for the data input file.

    摘要： A method for dynamically storing keys and values includes receiving a request for storing one or more keys in a key value Solid State drive (KV-SSD). The method further includes performing a storage operation for storing each key of the one or more keys in a node of a data structure of the KV-SSD. The storage operation includes allocating a first region in the node for storing the key, such that a size of the first region is equal to a size of the key. The storage operation further includes allocating a second region in the node for storing key metadata associated with the key, such that the second region is of a predetermined size. The storage operation further includes storing the key in the first region and the key metadata in the second region of the node.
