Specifically, after receiving the start signal of the storage system, the current and the precharge current of each storage unit group fed back by the detection unit are received.

Step 102: Determine the number of Devices in the storage unit group according to the current.

Since the current of each Device is constant, the number of Devices in the storage unit group can be determined according to the measured total current of each Device.

If the number of Devices is small (specifically, the current may be less than 50% of the maximum rated operating current), use the traditional power supply method for power supply; if the number of Devices is large (specifically, the current may be greater than 50% of the maximum rated operating current), then use Distributed power supply mode, that is, to supply power to each storage unit group successively according to a certain power supply sequence.

Step 104: When the number of Devices is greater than the preset threshold number, an enable signal is sent to the switch management unit, so that the switch management unit controls to turn on a preset number of switches, and powers on the storage unit group.

Specifically, when the enabling condition is met, the CPLD logic processing unit sends an enabling signal to the switch management unit, so that the switch management unit can control to turn on a preset number of switches to power on the storage unit group.

Step 105: After a preset time delay, control the next storage unit group to be powered on until all storage unit groups are powered on.

After the working state of the above-mentioned storage unit group tends to be stable, that is, after the preset time delay, continue to detect the real-time current, perform distributed power-on according to the current, and send a second enabling signal to power on the next storage unit group. Power on, and so on, until all storage unit groups at the back end of the storage server are turned on.
