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.

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.

Abstract: An apparatus, system, and method are disclosed for reconfiguring an array of solid-state storage elements. The method includes determining that one or more storage elements are unavailable to store data. The storage elements are configured in an array of N storage elements that each store a portion of a first ECC chunk and P storage elements that store first parity data corresponding to the first ECC chunk. The method includes generating a second ECC chunk comprising at least a portion of the data of the first ECC chunk. The method includes storing the second ECC chunk and associated second parity data across (N+P)?Z storage elements where 1?Z?P.

Abstract: An apparatus, system, and method are disclosed for managing data storage. The method includes determining that an error correcting code (ECC) block comprises uncorrectable errors. The ECC block is stored across a plurality of memory devices. The method includes iteratively substituting replacement data, within data of the ECC block, for individual memory devices of the plurality of memory devices to form substitute ECC blocks until one of the substitute ECC blocks is correctable using the error correcting code for the ECC block. The method includes providing corrected data from the correctable one of the substitute ECC blocks.

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.

Abstract: An apparatus, system, and method are disclosed for reconfiguring an array of solid-state storage elements protected using parity data. The storage element error module determines that one or more storage elements are unavailable to store data (“unavailable storage elements”). The storage element resides in an array with N number of storage elements storing a first ECC chunk and P number of storage elements storing first parity data. The reconfigure data read module reads data from storage elements other than the unavailable storage elements. The data regeneration module uses the first parity data to regenerate missing data from the first ECC chunk. The data reconfiguration module creates a second ECC chunk. The new configuration storage module stores a portion of the second ECC chunk and associated second parity data on (N+P)?Z number of storage elements, wherein 1?Z?P.

Abstract: An apparatus, system, and method are disclosed for power loss management in a nonvolatile data storage device. A monitor module initiates a power loss mode in the nonvolatile data storage device in response to a primary power source failing to supply electric power above a predefined threshold to the nonvolatile data storage device. A secondary power source supplies electric power to the nonvolatile data storage device for at least a power hold-up time during the power loss mode. A power loss module adjusts execution of in-process operations on the nonvolatile data storage device during the power loss mode so that essential in-process operations execute within the power hold-up time.

Abstract: An apparatus, system, and method are disclosed to increase data integrity in a redundant storage system. The receive module receives a read request to read data from a logical page spanning an array of N+P number of storage elements. The array of storage elements includes N number of the storage elements each storing a portion of an ECC chunk and P number of the storage elements storing parity data. The data read module reads data from at least a portion of a physical page on each of X number of storage elements of the N+P number of storage elements where X equals N. The regeneration module regenerates missing data. The ECC module determines if the read data and any regenerated missing data includes an error. The read data combined with any regenerated missing data includes the ECC chunk.

Abstract: An apparatus, system, and method are disclosed for detecting and replacing failed data storage. A read module reads data from an array of memory devices. The array includes two or more memory devices and one or more extra memory devices storing parity information from the memory devices. An ECC module determines, using an error correcting code (“ECC”), if one or more errors exist in tested data and if the errors are correctable using the ECC. The tested data includes data read by the read module. An isolation module selects a memory device in response to the ECC module determining that errors exists in the data read by the read module and that the errors are uncorrectable using the ECC. The isolation module also replaces data read from the selected memory device with replacement data and available data wherein the tested data includes the available data combined with the replacement data.
