Storwize Family Software improves Easy Tier capabilities to allow for up to three tiers of storage. Easy Tier users can now define their tiers making it possible to turn on Easy Tier between more than just solid-state devices and hard disk drives. These Easy Tier capabilities offer more alternatives for optimizing the storage you use. As you expand storage pools, Storwize Family Software also now provides automation to restripe data across the pools for optimal performance.
