Abstract
Described is a system that allows for the efficient management of reallocating data between tiers of an automated storage tiering system. In certain configurations, protected data that is stored within the storage system may include a user data portion and a redundant data portion. Accordingly, to conserve space on higher storage tiers, the system may separate user data from the redundant data when reallocating data between tiers. For example, the system may only allocate the user data portion to higher storage tiers thereby conserving the space that would otherwise be taken by the redundant data, which remains, or is demoted to a lower tier. Moreover, the reallocation may occur during scheduled reallocation cycles, and accordingly, the reallocation of the separated protected data may occur without any additional tiering overhead.
