Dynamic Tiering (HDT) Tier Utilization

Is there a way to push data down storage pool tiers to allow the additional spindles in lower tiers to activate and provide additional performance?


Here is the example:


HDP Pool - 680TB Total Usable Capacity

Broken Down by:

Tier 1 Pool

- 19TB Flash

- 98% Utilization

Tier 2 Pool

- 360TB 600GB 10k SAS

- 67% Utilization

Tier 3 Pool

- 300TB 4TB NL-SAS

- 0% Utilization


I know the NL-SAS tier will fill as the array gets more consumed, but if there a way to have 10-15% of the SAS Tier push down into the NL-SAS Tier without waiting for the SAS Tier to fill?


I feel like there is a simple setting to change that would make this happen.
