Optimizing data location in data storage arrays

A system for optimizing location of storage objects in a storage array, the system configured to:

• a primary storage array associated with a secondary storage array, the primary storage array and secondary storage array including auto-tiering functionality, wherein the secondary storage array is configured as a backup storage array for the primary storage array;
• a first auto-tiering module configured to derive tiering metadata for a storage object stored on the primary storage array;
• transmit the tiering metadata for the multiple storage object to the secondary storage array;
• receive, at the secondary storage array, tiering metadata derived at the primary storage array;
• a second auto-tiering module configured to initiate auto-tiering at the secondary storage array, wherein the received tiering metadata is used as input to the auto-tiering function when auto-tiering replicated storage objects associated with the tiering metadata;
• identify a failover event at the primary storage array;
• initiate failover for one or more production sites associated with the primary storage array from the primary storage array to the secondary storage array;
• derive subsequent data tiering metadata based on an activity level of the storage object activity occurring at the secondary storage array;
• and
• provide the subsequent data tiering metadata as input to the secondary storage array's auto-tiering function.
