Abstract
The system and methods disclosed herein relate to an improvement in automated data tiering technology. In these embodiments, users are able to weigh the importance of read, write, and pre-fetch operations in terms of tier placement within the data storage system. Data relocation evaluations are performed by an off-load engine, e.g., a graphics processing unit, which utilizes parallel processing on data arrays/vectors/extents. The data relocation candidates are identified via calculating a mobility score on an extent-by-extent basis. Data are then relocated within the various tiers of the data storage system.
