A Model for the Storage Resource Manager

The Storage Resource Manager has been proposed as a standard interface for high-end storage systems deployed on Grid architectures. In this paper we propose a conceptual model for the SRM that should supplement its API specification with a clear and concise definition of its underlying structural and behavioral concepts. This model would make it easier to define its semantics, it would help service and application developers, and provide for a more rigorous validation of implementations. Different notations are used as appropriate to define different aspects of the model.
