摘要： Apparatuses, systems, and methods are disclosed for indexing data of an append-only, log-based structure. A storage controller writes a plurality of data packets to a storage medium by sequentially appending the data packets to a log-based structure of the storage medium. The data packets may be associated with different logical identifiers belonging to a logical address space that is independent of physical storage locations on the storage medium. An indexing module writes an index segment associated with the plurality of data packets to the log-based structure. The index segment may include index entries for determining the logical identifiers of the data packets. The indexing module records, on the storage medium, information indicating where the index segment is written on the storage medium.

摘要： A method and apparatus for storing data packets in two different logical erase blocks pursuant to an atomic storage request is disclosed. Each data packet stored in response to the atomic storage request comprises persistent metadata indicating that the data packet pertains to an atomic storage request. In addition, a method and apparatus for restart recovery is disclosed. A data packet preceding an append point is identified as satisfying a failed atomic write criteria, indicating that the data packet pertains to a failed atomic storage request. One or more data packets associated with the failed atomic storage request are identified and excluded from an index of a non-volatile storage media.

摘要： A storage controller is configured to implement an atomic storage operation comprising a plurality of separate storage operations on a non-volatile storage medium. The storage controller may store persistent indicators to identify data that pertains to the atomic storage operation. An invalid shutdown may occur before the atomic storage operation is complete. A restart and recovery operation comprises a first scan of the non-volatile storage medium to identify data of the failed atomic storage operation. A physical trim note is stored on the non-volatile storage medium to identify the data of the failed atomic storage operation. The data may be identified by media address. Storage metadata is reconstructed in a second scan, which excludes the data and/or operations of the failed atomic storage operation.
