Abstract
A write request for the data object is received. The data object is stored at one or more of a plurality of storage nodes according to the write request. A storage manager catalog that maps a data object identification (DOID) for the data object is updated with an actual storage location of the data object, the DOID for a corresponding data object being calculated based on content of the data object, a plurality of data objects being organized into one or more storage volumes. The storage manager catalog includes a count of a number of instances of a data object that is currently referenced for each of the one or more storage volumes.
