Abstract
A storage control system includes performance monitor logic configured to track performance parameters for different volumes in a storage array. Service level enforcement logic is configured to assign target performance parameters to the different volumes and generate metrics for each of the different volumes identifying how much the performance parameters change for the different volumes responsive to changes in the amounts of tiering media allocated to the different volumes. Resource allocation logic is configured to allocate the tiering media to the different volumes according to the performance parameters, target performance parameters, and metrics for the different volumes.
