Dell Storage Manager 2020 R1 Administrator's Guide

View a Data Progression Pressure Report

For each storage type, the data progression pressure report displays how space is allocated, consumed, and scheduled to move across different RAID types and storage tiers. Use the data progression pressure report to make decisions about the types of disks to add to a Storage Center.

1. If the Dell Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2. Click the Storage tab.
3. In the Storage tab navigation pane, expand Storage Type, then select the individual storage type that you want to examine.
4. Click the Pressure Report subtab to view the data progression pressure report. By default, the most recent data gathered from the Storage Center is displayed.
5. To view a previously generated data progression report, select a report from the drop-down menu. Reports are identified by the date and time at which they were generated.
