Setting Background Task Rate
In 3DM, you can set the relative performance of background tasks (initializing, rebuilding, and verifying) in relation to normal I/O activity.
9000-series controllers show separate settings for Rebuild Rate and Verify Rate. (Initialization occurs at the Rebuild rate.) 7000- and 8000-series controllers show only one setting for Task Rate, which applies to both rebuild and verify rates.
Rebuild and verify tasks can be started manually or scheduled. For details about manually starting these processes, see Rebuilding Units and Verifying Units. For details about scheduling rebuild, verify, and other tasks, see Scheduling Background Tasks.
To change the background task rate
- Choose Management > Controller Settings from the menu bar.
- In the Background Task Rate section of the Controller Settings Page, select one of the five radio buttons to indicate the relative task rate for Rebuild and Verify Tasks.
The furthest left buttons set the firmware to the fastest rebuild and verify settings. This means that maximum processing time will be given to rebuilds or verifies rather than I/O. The furthest right buttons set the firmware to the slowest rebuild and verify settings, giving maximum processing time to I/O.
After you select one of the radio buttons, the page refreshes, and a message at the top confirms the change you have made.
For more information about these settings, see the reference section, Controller Settings Page.
