Abstract
A data storage system includes a processor, a system memory, and logical extents. Blocks of storage in one or more physical storage devices are allocated to each of the logical extents. The processor maintains a logical container for data objects and the volume includes one or more of the logical extents. The processor stores data objects that are uniquely identified by object identifiers in the logical extents. The processor also maintains a first index that is stored in the system memory and maps a range of the object identifiers to a second index. The second index is also stored in a logical extent and indicates storage locations of the data objects associated with the range of the object identifiers.
