Performance Priority
: To guarantee external IO task performance, internal IO task is totally stopped.
Protection Priority
: To guarantee internal IO task performance, external IO task would only take the
rest channel.
Balanced
: When both internal and external IO task exist, Balance ensures internal IO task occupy
certain channel without influencing external IO task.
Smart
