Improve performance
Easy Tier technology, an optional function for Storwize V3700, automatically and dynamically moves only the appropriate data to f lash storage, so users can achieve high performance without needing to manually create and manage storage-tier policies. Easy Tier automatically identifies highly-active data and moves only that data to f lash storage. The remaining data can be placed on higher capacity drives for the best value. Using Easy Tier, you can improve performance up to three times with
only five percent f lash storage capacity
