Implementing Auto Tiering requires pre planning around memory and sizing. Considerations and requirements for Auto Tiering include:

- Flash memory must be locally attached. Using network attached storage (NAS), storage area networks (SAN) or solutions such as AWS Elastic Block Storage (EBS) is considered not supported.
- Flash memory must be locally attached. Using network-attached storage (NAS), storage area networks (SAN), or solutions such as AWS Elastic Block Storage (EBS) is not supported.
- Flash memory must be dedicated to Auto Tiering and not shared with other parts of the database, such as durability, binaries, or persistence.
- For the best performance, the SSDs should be NVMe based, but SATA can also be used.
- The available flash space must be greater than or equal to the total database size (RAM+Flash). The extra space accounts for write buffers and [write amplification](https://en.wikipedia.org/wiki/Write_amplification).
