Controller Settings Page

Figure 21. Controller Settings Page

The Controller Settings page appears when you choose Management > Controller Settings from the menu bar.

The Controller Settings page lets you view and change settings that affect the units on the controller specified in the drop-down list on the menu bar.

Background Task Rate

The Background Task Rate fields let you change the balance of background tasks (rebuild and verify) and I/O performed by the controller.

9000-series controllers show separate settings for Rebuild Rate and Verify Rate, as shown in Figure 21. 7000- and 8000-series controllers show only one setting for Task Rate; it applies to both rebuild and verify rates.This rate is not persistent following a reboot for 7/8000.

The 5 radio buttons let you set the ratio at which rebuilds and verifies are performed. The furthest left buttons set the firmware to the fastest rebuild and verify settings. This means, 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.
