Managing Dynamic Tiering and active flash

Parent Topic

• Dynamic Tiering and active flash

  Hitachi Dynamic Tiering (HDT) simplifies storage administration by automatically optimizing data placement in 1, 2, or 3 tiers of storage that can be defined and used within a single virtual volume. Tiers of storage can be made up of internal or external (virtualized) storage, and use of HDT can lower capital costs. Simplified and unified management of HDT allows for lower operational costs and reduces the challenges of ensuring applications are placed on the appropriate classes of storage.
