Abstract

One embodiment of the present invention provides an efficient data-object-related-request-routing method and component used within a dynamic, distributed data-storage system for efficiently routing data objects to component data-storage systems when component data-storage systems frequently become unavailable and new component data-storage systems are frequently added to the dynamic, distributed data-storage system. The data-object-related-request-routing method is employed in data-object store operations and data-object retrieval operations. The data-object store and retrieval operations, in turn, are based on identifying certain preferred component data-storage systems within the distributed data-storage system by a component-data-storage-system-ranking method.

Claims16

Dependent claims

A data-object-related-request routing method employed in a distributed electronic-data storage system comprising a routing component and component data storage systems, the data-object routing method comprising:

computing, by the routing component of the distributed electronic-data storage system, a number of ranks for the number of component data storage systems based on data contained in the data object and, for each rank, on an identifier of the corresponding component data storage system that identifies a set of data stored in the component data storage system;
selecting, by the routing component of the distributed electronic-data storage system, one or more target component data storage systems based on the computed ranks for each operational component data storage system within the distributed electronic-data storage system;
and
directing, by the routing component of the distributed electronic-data storage system, a data-object-related request to the selected one or more target component data storage systems.
