This dissertation demonstrates that the conventional approach for evaluating the performance of an I/O subsystem design, which is based on standalone subsystem models, is too narrow in scope. In particular, conventional methodology treats all I/O requests equally, ignoring differences in how individual request response times affect system behavior. As a result, it often leads to inaccurate performance predictions and can thereby lead to incorrect conclusions and poor design choices. A new methodology, which expands the model's scope to include other important system components (e.g., CPUs and system software), is proposed and shown to enable accurate predictions of both subsystem and overall system performance.
