Dynamic event driven storage system optimization

摘要

An improved technique involves proactively adjusting data storage system configuration in response to detecting external events. The improved technique predicts load changes based on historical correlations between events and load changes and directs an administrator to modify system configurations to prepare for the predicted changes in load. Advantageously, the improved technique enables administrators to better prepare for changes in load brought about by external events and thus to better maintain required service levels. Further, the improved technique reduces need for stressful and urgent responses by system administrators.

主权项

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.
