Abstract
A method is used in managing data relocation in storage systems. Metadata of a slice of a storage tier in a data storage system is evaluated for migrating the slice 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 the evaluation, relocation of the slice of the storage tier is effected. The metadata of the slice indicates whether the slice includes user data.
