  • Publication number: 20160110252
    Abstract: Apparatuses, systems, methods, and computer program products are disclosed for distributing error-correction codes. A correction module is configured to determine an error correction code (ECC) code word for storage on one or more non-volatile storage media. A mapping module is configured to determine one or more addresses for the ECC code word so that a portion of the ECC code word is stored at a first physical address within a first set of strings of storage cells of the one or more non-volatile storage media and a portion of the ECC code word is stored at a different physical address within a second set of strings of storage cells of the one or more non-volatile storage media. A storage module is configured to cause the ECC code word to be stored in the one or more non-volatile storage media based on the determined one or more addresses.

  • Patent number: 9304853
    Abstract: In various embodiments, an apparatus, system, and method may increase data integrity in a redundant storage system. In one embodiment, a request is received for data stored at a storage system having a plurality of storage elements, where one or more of the plurality of storage elements include parity information. A determination is made that one of the plurality of storage elements is unavailable, the unavailable storage element being a functional storage element and including at least a portion of the data. Responsive to the determination, the data is reconstructed based on at least a portion of the parity information and data from one or more of the plurality of storage elements other than the unavailable storage element; a response is provided to the request such that the response includes the reconstructed data.

  • Patent number: 9306599
    Abstract: Apparatuses, systems, and methods are disclosed for reconfiguring an array of storage elements. A storage element error module is configured to determine that one or more storage elements in an array of storage elements are in error. An array of storage elements stores a first ECC block and first parity data generated from the first ECC block. A data reconfiguration module is configured to generate a second ECC block comprising at least a portion of data of a first ECC block. A new configuration storage module is configured to store a second ECC block and associated second parity data on fewer storage elements than a number of storage elements in an array.

  • Publication number: 20160092135
    Abstract: An adaptive logical storage element comprises a plurality of solid-state storage elements accessible in parallel. The logical storage element includes logical storage units, which may include logical page, logical storage divisions (erase blocks), and so on. Each logical storage unit comprises a plurality of physical storage units. A logical storage unit may include one or more physical storage units that are out-of-service (OOS). The OOS status of logical storage units is tracked by OOS metadata. When data is stored on the logical storage element, padding data is provided to physical storage units that are OOS, and valid and/or parity data is provided to in-service physical storage units. A write data pipeline accesses the OOS metadata to insert padding data, and a read data pipeline accesses the OOS metadata to strip padding data.

  • Patent number: 9250817
    Abstract: A storage layer presents logical address space of a non-volatile storage device. The storage layer maintains logical interfaces to the non-volatile storage device, which may include arbitrary, any-to-any mappings between logical identifiers and storage resources. Data may be stored on the non-volatile storage device in a contextual format, which includes persistent metadata that defines the logical interface of the data. The storage layer may modify the logical interface of data that is stored in the contextual format. The modified logical interface may be inconsistent with the existing contextual format of the data on the non-volatile storage media. The storage layer may provide access to the data in the inconsistent contextual format through the modified logical interface. The contextual format of the data may be updated to be consistent with the modified logical interface in a write out-of-place storage operation.

  • Publication number: 20150333773
    Abstract: A storage module is configured to store data segments, such as error-correcting code (ECC) codewords, within an array comprising a plurality of columns. The ECC codewords may comprise ECC codeword symbols. The ECC symbols of a data segment may be arranged in a horizontal arrangement, a vertical arrangement, a hybrid channel arrangement, and/or vertical stripe arrangement within the array. The individual ECC symbols may be stored within respective columns of the array (e.g., may not cross column boundaries). Data of an unavailable ECC symbol may be reconstructed by use of other ECC symbols stored on other columns of the array.

  • Patent number: 8972627
    Abstract: An apparatus, system, and method are disclosed for managing operations for data storage media. An adjustment module interrupts or otherwise adjusts execution of an executing operation on the data storage media. A schedule module executes a pending operation on the data storage media in response to adjusting execution of the executing operation. The pending operation comprises a higher execution priority than the executing operation. The schedule module finishes execution of the executing operation in response to completing execution of the pending operation.

  • Publication number: 20150032982
    Abstract: A storage layer is configured to implement efficient open-close consistency operations. Open close consistency may comprise preserving the original state of a file until the file is closed. The storage layer may be configured to clone a file in response to a file open request. Cloning the file may comprise referencing file data by two separate sets of identifiers. One set may be configured to reflect file modifications, and the other set may be configured to preserve the original state of the file. Subsequent operations configured to modify the file may be performed in reference to one of the sets of identifiers, while the storage layer provides access to the unmodified file through the other set of identifiers. Closing the file may comprise merging the sets of identifiers according to a merge policy.
