Dynamic Tiering uses tiers to manage data storage. It classifies the specified drives in the pool into tiers (storage hierarchy). Up to three tiers can be defined in a pool depending on the processing capacity of the data drives. Tiering allocates more frequently accessed data to the upper tier and less frequently accessed data, stored for a long period of time, to the lower tier.
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.
