The HT-7U data system is being designed to support the HT-7U superconducting tokamak. For the HT-7U to achieve its mission of extremely long pulse and steady-state operation, the HT-7U data system must be flexible and robust. Corresponding to the various operation modes of the HT-7U experiment, a variety of system configurations and workload models are considered. A trace-driven simulation-based method and steady-state operational analysis technique is used for performance evaluation. These analyses show that much better performance may be obtained by applying the performance optimization techniques of fast switching networking, data compression, caching/buffering, pipelining, a real-time operating system, a real-time database, etc
