If all drives do spin up together, it will result in large power consumption. To reduce the power consumption, driver provide an option to make a small group of drives (say 3 or 4 drives together) to do the spin up. The delay between two spin up group and no of drives to spin up (group) can be programmed by the customer in seeprom and driver will use it to control the spinup.
