Abstract

A data storage system (100) includes a storage media (132) having stored thereon data configured as a plurality of objects (124-126), each object having attributes indicative of characteristics of the object (124-126). The objects (124-126) include a redundancy object (412) storing redundancy information. A control component (150) is operably coupled to the storage media (132) and is configured to provide an interface (128) to the objects (124-126). The interface (128) exposes methods (Ï-N) which are invoked to access the objects (124-126).
