Abstract
A method is used in managing data relocation in storage systems. Data access activity information is gathered for a set of slices of a storage tier in a data storage system for migrating the set of slices from the storage tier to another storage tier. The data storage system includes a first storage tier and a second storage tier configured such that performance characteristics associated with the first storage tier is superior to the second storage tier. Based on a pattern indicated by the data access activity information, a temperature for the set of slices is determined by applying a predictive analysis technique. Based on the determination, relocation of data is effected in the storage system.
