1. A method comprising: requesting, from an analysis engine, data representing a prediction of an impact on a storage system of implementing a planning action on the storage system; receiving the data representing the prediction of the impact based on a first model of the storage system, wherein the data representing the prediction of the impact includes parameters indicative of modeling error and modeling confidence indicative of reliability of the first model of the storage system to predict the impact of implementing the planning action on the storage system; and determining, using a processor, whether to execute the planning action, wherein determining whether to execute the planning action includes requesting second data representing a second prediction of the impact on the storage system using a second model of the storage system when one of the parameters indicative of modeling confidence is below a predetermined value.
