When does Pressure down actually move

When I see downward pressure on my pressure report in Storage Manager, when will that data actually move?  At the next snapshot? When the next snapshot expires? or 12 days from when the down pressure is reported?

Thanks for any insight,

Bill

According to Understanding RAID with Dell SC Series Storage:

5.1 Data Progression

Data Progression moves data within a virtualized storage environment, between tiers and drive types, as well as among multiple RAID levels within the same tier for a constant balance of performance and cost. Data Progression runs every 24 hours to assess disk use and moves data to disk space that is more efficient for the data usage. By default, Data Progression runs each day at 7 PM, but this schedule can be changed in the SCOS settings. The storage profile applied to each volume determines Data Progression behavior.
