Abstract
A multilayered index is implemented for data stored in a data storage system. The multilayered index may include a granular index that specifies the location of specific files or abstractions within the data storage system, while a skip table specifies segments of the abstractions, and may point to both the granular index and the data storage devices of the data storage system. In redundancy coded systems, the use of multilayered indices may enable asynchronous retrieval of data during normal or adverse operation (such as during periods of varying data availability).
