Abstract : Storage device performance prediction is a key element of self-managed storage systems and application planning tasks, such as data assignment and configuration. Based on bagging ensemble, we proposed an algorithm named selective bagging classification and regression tree SBCART to model storage device performance. In addition, we consider the caching effect as a feature in workload characterization. Experiments indicate that caching effect added in feature vector can substantially improve prediction accuracy and SBCART is more precise and more stable compared to CART.
