A framework for accessing general object storage

With computer application popularizing and storage capacity increasing, research for NAS and SAN storage system are gradually turning to OBS The OBS will become the next wave of network storage technology. In this paper a framework for accessing general object storage(GOS) is presented. The GOS system adopts a basic unit called Storage Device Object(SDO) and proposes an access model that contains Upper Layer, Middle Layer and Lower Layer. It not only enriches the concept of object, but also gives a compatible object interface in the network storage systems. So it allows applications to access to different SDO according their attributes. Therefore it is more universal.
