<p>Systems, methods, and apparatus for providing data storage services storage using self-organizing replica management. In one embodiment, a cellular system operates to store storage objects, for example, data files, for clients. The system stores the storage objects as generally more than one substitutable replica, with each replica being stored on a separate cell. In some aspects, the system maintains multiple layers of overlapping trees and uses them for managing storage object replicas. In other aspects, a single self specializing substitutable cell performs dynamic specialization of itself in the system, while persistence is provided by the system as a whole. In other aspects, the system gives replicas special status while their storage object is being updated and returns them to a state of being fully substitutable after all changes have been successfully propagated to the replicas.</p> |
