About virtualizing storage tiers
Smart Tiers functionality lets you configure the monitoring frequency modes at which data is accessed
and relocate that data in a specific pool and tier based on the results.
For example, you might create a pool that combines volumes having different cost performances,
such as combining high-speed volumes (SSD, FMD, or SAS) with inexpensive low-speed volumes
(SATA). The data in this pool is then automatically relocated among the volumes depending on the
I/O load:
•
High-load pages are allocated to high-speed volumes
•
Low-load pages are allocated to low-speed volumes
