9.2.1 Automated Storage Tiering
■
Solution Overview
Automated Storage Tiering is a function that detects frequently accessed data by monitoring data access to
the storage, and redistributes data between drives of various types according to the policy that is set.
By storing the less frequently accessed data to cost effective Nearline SAS disks with a large capacity, storage
cost can be reduced. By storing the frequently accessed data to high performance SSDs, response time are
reduced and performance is improved.
In addition, by automating operation, data management hours and management costs can be reduced.
