Run efficiency operations depending on the amount of new data written
You can modify the efficiency operation schedule to run deduplication or data compression when the number of new blocks written to the volume after the previous efficiency operation (performed manually or scheduled) exceeds a specified threshold percentage.
schedule option is set to
auto, the scheduled efficiency operation runs when the amount of new data exceeds the specified percentage. The default threshold value is 20 percent. This threshold value is the percentage of the total number of blocks already processed by the efficiency operation.
volume efficiency modifycommand with the
auto@numoption to modify the threshold percentage value.
numis a two-digit number to specify the percentage.
The following command modifies the threshold percentage value to 30 percent for the volume VolA:
