Abstract
A technique is used for optimizing data location in data storage arrays. A primary storage array is associated with a secondary storage array, the primary storage array and secondary storage array including auto-tiering functionality, where the secondary storage array is configured as a backup storage array for the primary storage array. Tiering metadata is derived for a storage object stored on the primary storage array. The tiering metadata is transmitted to the secondary storage array. Auto-tiering is initiated at the secondary storage array, where the received tiering metadata is provided as input to the secondary storage array's auto-tiering function when auto-tiering replicated storage object associated with the tiering metadata.
