存储管理系统

The information collecting module deployed on resources is designed to obtain state information of resources; the information node server is introduced for assembling and managing resource information. The XML format is used to formalize the data source and information transport. Meanwhile adopt native-XML database technology for direct data store and process. The interface for information query and resource information filtering is implemented through Web service capsulation.
