FIG. 1B is a schematic block diagram illustrating one embodiment of a system 101 for object management in a storage device in accordance with the present invention. The system 101 includes one or more storage devices 150, each with a storage controller 152 and one or more data storage devices 154, and one or more requesting devices 155. The storage devices 150 are networked together and coupled to one or more requesting devices 155. The requesting device 155 sends object requests to a storage device 150a. An object request may be a request to create an object, a request to write data to an object, a request to read data from an object, a request to delete an object, a request to checkpoint an object, a request to copy an object, and the like. One of skill in the art will recognize other object requests. |
