    摘要: An apparatus, system, and method are disclosed for bad block remapping. A bad block identifier module identifies one or more data blocks on a solid-state storage element as bad blocks. A log update module writes at least a location of each bad block identified by the bad block identifier module into each of two or more redundant bad block logs. A bad block mapping module accesses at least one bad block log during a start-up operation to create in memory a bad block map. The bad block map includes a mapping between the bad block locations in the bad block log and a corresponding location of a replacement block for each bad block location. Data is stored in each replacement block instead of the corresponding bad block. The bad block mapping module creates the bad block map using one of a replacement block location and a bad block mapping algorithm.

    摘要: An apparatus, system, and method are disclosed for coordinating storage requests in a multi-processor/multi-thread environment. An append/invalidate module generates a first append data storage command from a first storage request and a second append data storage command from a second storage request. The storage requests overwrite existing data with first and second data including where the first and second data have at least a portion of overlapping data. The second storage request is received after the first storage request. The append/invalidate module updates an index by marking data being overwritten as invalid. A restructure module updates the index based on the first data and updates the index based on the second data. The updated index is organized to indicate that the second data is more current than the first data regardless of processing order. The modules prevent access to the index until the modules have completed updating the index.

    摘要: An apparatus, system, and method are disclosed for converting a storage request to an append data storage command. A storage request receiver module receives a storage request from a requesting device. The storage request is to store a data segment onto a data storage device. The storage request includes source parameters for the data segment. The source parameters include a virtual address. A translation module translates the storage request to storage commands. At least one storage command includes an append data storage command that directs the data storage device to store data of the data segment and the one or more source parameters with the data, including a virtual address, at one or more append points. A mapping module maps source parameters of the data segment to locations where the data storage device appended the data packets of the data segment and source parameters.
