Data management requirements for high energy physics in the year 2000

It is noted that the data storage and management requirements of future high energy physics (HEP) experiments, such as those planned for the Large Hadron Collider or the Superconducting Supercollider, will greatly exceed those of current experiments. A global requirement for the storage of 10 to 100 petabytes of new HEP data per year is foreseen. The author discusses the lessons learned from existing home-grown solutions, such as those described at previous symposia, current trends in data management and storage, and future requirements. Particular emphasis is placed on the specific needs of HEP, integration with user-level code, and the suitability of the IEEE Mass Storage System Reference Model and commercial solutions in such an environment. The specific needs of end users, data managers, and central support staff are addressed.<
