Set Background Initialization Rate

Does my controller support this feature? See "Supported Features."

The Set Background Initialization Rate task changes the amount of system resources dedicated to the background initialization task. See "Background
Initialization on PERC 3/SC, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, and 4e/Di Controllers" for more information on the background initialization task.

The background initialization rate, configurable between 0% and 100%, represents the percentage of the system resources dedicated to running the
background initialization task. At 0%, the background initialization will have the lowest priority for the controller, will take the most time to complete, and will
be the setting with the least impact to system performance. A background initialization rate of 0% does not mean that the background initialization is stopped
or paused.

At 100%, the background initialization will be the highest priority for the controller, will minimize the background initialization time, and will be the setting with
the most impact to system performance.

To change the controller's background initialization rate:
1. Type a numerical value in the New Background Initialization Rate text box. The value must be within the 0 – 100 range.
2. Click Apply Changes. If you want to exit and cancel your changes, click Go Back to Previous Page.
