-Set the `disk_time_available_scale_<used-device-type>` configuration parameter equal to the calculated value of $D$, multiplied by 1000 and rounded. We assume that the physical devices in the user cluster are comparable in performance to the baseline; hence, by default, the `disk_time_available_scale_<used-device-type>` parameter is set to 1000.
