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.
