Abstract
Predictors of future application activity/inactivity are used in combination with monitored data access activity to prompt movement of data between tiers of storage. The apparent amount of activity for data associated with an application that is expected to become active to be increased even before data associated with that application becomes active. Further, the apparent amount of activity for data associated with an application that has become inactive is rapidly decreased by overriding algorithms that control rate of change to counter thrashing.
