US Patent 9460399 Dynamic event driven storage system optimization

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.
