A new approach in the modeling and generation of synthetic disk workload

Shows a new approach to generate synthetic disk workload. The work presented is based on previous results obtained from the analysis of real disk traces. The proposed disk workload generation model can capture the heavy-tailed behavior of real disk workload, a critical feature to reproduce disk subsystem congestion. The generator provides synthetic workload much more accurately than commonly-used models. Since the workload plays a critical role in performance evaluations, having a more accurate disk workload generator is important for storage researchers in order to obtain fair and unbiased performance predictions.
