- Tiering License
- 2 tiers
By enabling users to flexibly assign applications to tiers distinguished by different drive types and RAID levels, automated storage tiering provides an architecture that fully leverages the advantages of different storage media, including SSDs for high-performance data storage. With automated storage tiering, users can greatly optimize storage performance and increase ROI. As part of automated storage tiering, data is migrated between tiers based on data usage patterns and user-configured policies. With tiering implemented on the sub-volume level, data can be moved in a highly granular fashion. Data migration achieves efficient distribution of data, and ensures that SSDs and other high-performance drives have the necessary storage space to deal with mission-critical applications.
