    Abstract: A storage controller is configured to append data to a sequential log. The data may be appended sequentially within erase regions of the non-volatile storage medium. An order of the sequential log may be defined by, inter alia, the order in which the erase regions are filled and/or the sequential order of physical storage locations and/or addresses within the erase regions. The erase regions may comprise sequence information which may be applied in response to recovering the erase regions, appending data to the erase regions, or the like. Data appended to the sequential log may be associated with source parameters, which may include a virtual identifier of the data. The physical storage location of the data on the non-volatile storage medium may be independent of the source parameters. The sequential log may, therefore, comprise a set of mappings between virtual identifiers and physical storage locations.

    Abstract translation: 存储控制器被配置为将数据附加到顺序日志。 数据可以顺序地附加在非易失性存储介质的擦除区域内。 顺序日志的顺序可以通过尤其是擦除区域被填充的顺序和/或擦除区域内的物理存储位置和/或地址的顺序来定义。 擦除区域可以包括响应于恢复擦除区域而被应用的序列信息,将数据附加到擦除区域等。 附加到顺序日志的数据可以与源参数相关联,源参数可以包括数据的虚拟标识符。 数据在非易失性存储介质上的物理存储位置可以独立于源参数。 因此,顺序日志可以包括虚拟标识符和物理存储位置之间的一组映射。
