%X Performance is a key factor in storage management systems.To improve storage performance could reduce the TCO dramatically.As one of the most important elements in performance optimization,data migration needs a more reasonable model to decide what and where to migrate.A measurable method for evaluating the value of every data block in a disk was proposed.Comparing with the hotspots detecting system that focuses on IO characters,more factors were taken into consideration in this model.To establish the model...
