Dynamic Tiering overview
Dynamic Tiering is a software that helps you reduce storage costs and increase storage performance by supporting a volume configured with different storage media of different cost and performance capabilities. This support allows you to allocate data areas with heavy I/O loads to higher-speed media and to allocate data areas with low I/O loads to lower-speed media. In this way, you can make the best use of the capabilities of installed storage media. Up to three storage tiers consisting of different types of data drives are supported in a single pool of storage.
