(3) Priority specification
For setting and displaying the priority of the background tasks (Rebuild, Patrol Read, and Consistency Check)
for the RAID controller, the WebBIOS uses numerical values while the Universal RAID Utility uses three levels
of high, middle, and low. The table below shows the correspondence between the numerical value ranges and
levels for each item. In this case, the priority is the percentage of the background task processing to all
processes being processed by the RAID controller.
