    摘要: Methods for indexing data of an append-only, log-based structure include writing 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 associated with different logical identifiers belonging to a logical address space that is independent of physical storage locations on the storage media. The methods may further include writing an index segment associated with the plurality of data packets to the log-based structure, the index segment comprising index entries for determining the logical identifiers of the data packets and recording, on the storage media, information indicating where the index segment is written on the storage medium.

    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.
