The emerging storage management paradigm

The authors present a summary of important challenges in managing and addressing the data of large commercial and governmental installations and the solutions that are arising from industry, national laboratories, and standards organizations. These issues are viewed from the perspective of a shift away from the paradigm of centralized, sequential storage systems toward a new paradigm of distributed, network-based, parallel storage systems. The challenges of technology discussed include high-speed storage devices, communications, and parallel computing. The relationship between managing data and managing storage is considered, with emphasis on scientific data objects. The challenge of integrating components from many vendors is also discussed
