1. A method of configuring resources of a data storage system, the method comprising: receiving a set of event notifications from a set of notification sources, each of the set of event notifications describing an event external to the data storage system; accessing a database that stores correlation scores between event notifications and subsequent loading of the resources of the data storage system to identify a set of correlation scores that the database associates with the received set of event notifications; generating a prediction, based on the set of correlation scores accessed from the database, of changes in loading on the resources of the data storage system in response to the received set of event notifications; and changing a configuration of the resources of the data storage system in response to the prediction of changes in loading on the resources of the data storage system to proactively prepare for changes in loading on resources based on historical correlations.
