Description

Although the current SCM-issued replication commands can be controlled via parameters, many clusters experience distinct business peak and off-peak periods. Therefore, adding a parameter to indicate non-peak business periods and using a ratio to represent the InFlightLimit proportion between off-peak and peak periods would help. 
This approach can prevent replication from causing increased DN iowait during peak periods, while fully utilizing DN resources during off-peak periods to accelerate replication.
