SYSTEMS AND METHODS FOR VIRTUALIZING STORAGE SYSTEMS AND MANAGING DATA INDEPENDENTLY

摘要

Method, data processing systems, and computer program products are provided for virtualizing and managing a storage virtualization system (SVS) in a storage management architecture. Source data is copied from the source storage media to target data in a target storage media based on a predefined copy policy in a copy mapping table. A relation between the source data and the target data is tracked in a copy mapping table. It is determined if a copy of the requested data exists using the copy mapping table.
