Abstract
Methods and systems for concurrently reading direct and indirect data blocks of a data object stored in a network storage server system. In one embodiment, upon receiving a request to read a data object, the storage server identifies a location of an indirect data-block of the data object and a total number of direct data-blocks associated with the data object. Using this information, the storage server concurrently reads, using a single read operation, both the indirect data-block and a specific number of data blocks that are contiguous with the location of the indirect data-block. The specific number is commensurate with the total number of direct-data blocks associated with the data object. In one embodiment, the storage server verifies whether the data object is represented using a contiguous-mode layout scheme before performing the concurrent single-read operation to read the data object.
