摘要： An apparatus, system, and method are disclosed for efficiently mapping virtual and physical addresses. A forward mapping module uses a forward map to identify physical addresses of data of a data segment from a virtual address. The data segment is identified in a storage request. The virtual addresses include discrete addresses within a virtual address space where the virtual addresses sparsely populate the virtual address space. A reverse mapping module uses a reverse map to determine a virtual address of a data segment from a physical address. The reverse map maps the data storage device into erase regions such that a portion of the reverse map spans an erase region of the data storage device erased together during a storage space recovery operation. A storage space recovery module uses the reverse map to identify valid data in an erase region prior to an operation to recover the erase region.

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.

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 determining a read voltage threshold for solid-state storage media. A data set read module reads a data set from storage cells of solid-state storage media. The data set is originally stored in the storage cells with a known bias. A deviation module determines that a read bias for the data set deviates from the known bias. A direction module determines a direction of deviation for the data set. The direction of deviation is based on a difference between the read bias of the data set and the known bias. An adjustment module adjusts a read voltage threshold for the storage cells of the solid-state storage media based on the direction of deviation.

摘要： An apparatus, system, and method are disclosed for a shared, front-end, distributed redundant array of independent drives (“RAID”). A multiple storage request receiver module receives at least two storage requests from at least two clients to store file or object data in one or more storage devices of a storage device set. The storage requests are concurrent and have at least a portion of the data in common. The storage device set includes autonomous storage devices forming a RAID group. Each storage device is capable of independently receiving storage requests from a client over a network. A striping module calculates a stripe pattern and writes N data segments per stripe to N storage devices. A parity-mirror module writes a set of N data segments to parity-mirror storage devices. A sequencer module ensures completion of a first storage request prior to executing a second storage request.

摘要： An apparatus, system, and method are disclosed for allocating non-volatile storage. The storage device may present a logical address, which may exceed a physical storage capacity of the device. The storage device may allocate logical capacity in the logical address space. An allocation request may be allowed when there is sufficient unassigned and/or unallocated logical capacity to satisfy the request. Data may be stored on the non-volatile storage device by requesting physical storage capacity. A physical storage request, such as a storage request or physical storage reservation, when there is sufficient available physical storage capacity to satisfy the request. The device may maintain an index to associate logical identifiers (LIDs) in the logical address space with storage locations on the storage device. This index may be used to make logical capacity allocations and/or to manage physical storage space.

摘要： A storage system implements a sparse, thinly provisioned logical-to-physical translation layer. The storage system may perform operations to modify logical-to-physical mappings, including creating, removing, and/or modifying any-to-any and/or many-to-one mappings between logical identifiers and stored data (logical manipulation operations). The storage system records persistent metadata to render the logical manipulation (LM) operations persistent and crash-safe. The storage system may provide access to LM functionality through a generalized LM interface. Clients may leverage the LM interface to efficiently implement higher-level functionality and/or offload LM operations to the storage system.
