iRBO: Intelligent Role-Based Object for Object-Based Storage Device

The intelligence of Object-based Storage Device (OSD) is crucial for an autonomous Object-based Storage Device Cluster (OSDC) and the intelligence of OSD depends on the intelligent Objects. Traditionally, object defined in OSD-2 draft is the container of data and attributes (such as user object) and lacks for intelligence which is the basis of an intelligent OSD. Consequently, the construction of an intelligent object will catch the fancy of most researchers. The task of traditional object is similar to each other and some special tasks aren´t taken by the specific objects. So some specific objects are urgent needed to be added into OSD for the special missions. This paper presents intelligent Role-Based Object (iRBO) for OSD. The construction of intelligent object is proposed firstly. Methods, rules, trigger and feed back mechanism are introduced into object defined in OSD-2 draft, so an object is comprised of data, attributes, methods, rules, trigger and feed back mechanism. After the relationship among these six components is built up, the object is no longer passive, but active. Then, the model of iRBO is discussed and some specific objects for special missions are introduced.
