My guess is it lowers the clock speed. To bring this into the realm of
Python, here's something you might try:

python -m test.pystone
echo "min_power" | sudo tee
/sys/class/scsi_host/host*/link_power_management_policy
python -m test.pystone

My guess is that you will see the pystone value reduced after issuing
the min_power command.
