    摘要: 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.

    摘要: 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.

    摘要: 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.
