Abstract

Requests to access specific ones of a plurality of stored objects are processed by multiple access nodes. A separate access history is maintained for each access node. Each access history identifies stored objects most recently accessed through the specific node. A separate predicted access future is maintained for each stored object. A predicted access future associated with a specific stored object can be in the form of a listing of stored objects statistically predicted to be those most likely to be accessed within a given temporal proximity after the specific stored object is accessed. Each predicted access future is determined based on inversion of maintained access histories. Responsive to receiving an access request for a specific stored object, the predicted future associated with the requested object is read, a specific number of additional stored objects identified in the associated predicted future is pre-fetched from slower to faster storage.
