## Changing the rebuild rate

(Startable-CD mode only.)

Use this action to change the rebuild rate.

1. Click a controller from the Main Tree.
2. Click Actions --> Change rebuild rate.
3. Click High, Medium, or Low rate.

When the rebuild rate is High, the rebuild I/O request gets high priority in the controller execution order.

If you change the rebuild rate from High to Medium in a heavily loaded system, the rebuild time can increase but provide better system performance.

If you change the rebuild rate from High or Medium to Low in a moderate to heavily loaded system, the rebuild time can increase, but provide better system performance.
