Abstract
A data location table master system generates a master data location table storing associations of tokens with storage nodes for varying responsibility levels. When the master data location table is updated, the data location table master system updates storage nodes affected by the update as well as other storage nodes and application nodes in the system. Then, the storage nodes and the application nodes store a copy of the master data location table. A token migration and synchronization process reallocates data object storage among the storage nodes based on the updated master data location table.
