Priority settings
For setting and displaying the priority of the background tasks (Rebuild, Patrol Read, and Consistency Check)
for the RAID Controller, WebBIOS uses numerical values while 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.
