The Flexible service level enables you to adjust throughput and size limits independently. This service level is designed for demanding applications such as Oracle or SAP HANA. You can also use the Flexible service level to create high-capacity volumes with (relatively) low throughput requirements or the reverse: low-capacity volumes with high throughput requirements. The minimum throughput to be assigned to a Flexible capacity pool is 128 MiB/second regardless of the pool quota. The first 128 MiB/s of throughput, known as the baseline, is included in the Flexible service level. The maximum throughput is 5 x 128 x the size of the capacity pool in TiB. For more information see [Flexible service level throughput examples](#flexible-examples). You can assign throughput and capacity to volumes that are part of a Flexible capacity pool in the same way you do volumes that are part of a manual QoS capacity pool of any service level. Cool access isn't currently supported with the Flexible service level.

* The minimum throughput for Flexible service level capacity pools is 128 MiB/second. Maximum throughput is calculated based on the size of the capacity pool using the formula 5 x 128 x capacity pool size in TiB. If your capacity pool is 1 TiB, the maximum is 640 MiB/second (5 x 128 x 1). For more examples, see [Service levels for Azure NetApp Files](azure-netapp-files-service-levels.md#flexible-examples).

* You can increase the throughput of a Flexible service level pool at any time. Decreases to throughput on Flexible service level capacity pools can only occur following a 24-hour cool-down period. The 24-hour cool-down period initiates after any change to the throughput of the Flexible service level capacity pool.
