After enabling Qtier on a storage pool, why is frequently accessed data still in a lower tier when it should be moved to a higher tier?
Applicable products:
- QTS
- Storage & Snapshots
To optimize NAS access speeds and system performance, Qtier automatically analyzes usage patterns on the NAS to determine the ideal off-peak hours for moving data. After enabling Qtier, it can therefore take some time before all of your frequently accessed data is moved to a higher tier for better read and write performance, and your infrequently accessed data is moved to a lower tier for more cost-effective data storage.
If you know specific hours when access to the NAS is not needed, you can set a tiering schedule, or manually start tiering data, by following these steps:
- Log on to QTS.
- Go to Storage & Snapshots > Storage > Storage/Snapshots.
- Select a Qtier storage pool.
- Click Manage. The Storage Pool Management window opens.
- Go to the Qtier Auto Tiering tab.
- Click Tiering Schedule. The Qtier Auto Tiering Schedule Settings window opens.
- Select Manually set tiering schedule.
- Specify the hours on the calendar.
- Optional: Specify the number of minutes past the hour to start tiering.
- Optional: Select Run now.
- Click Apply.
If your NAS model supports Cache Acceleration, you can also increase your data access speed immediately by creating an SSD cache.
