US Patent 10146469 Dynamic storage tiering based on predicted workloads

A technique for performing storage tiering in a data storage system includes monitoring storage demands over time to generate a time-based record of storage demands. Based on the time-based record, the data storage system makes predictions of future demand and proactively performs storage tiering based on the predictions. The technique therefore readies the data storage system for predictable changes in demand, such that, should those changes occur, the data storage system is already configured to manage them efficiently.
