The embodiment of the invention provides a hard disk power-on control method and device. The method includes: obtaining a quota current margin according to the peak value difference of the quota current supplied to the hard disk by the power supply and the power supply real-time current supplied to the hard disk by the power supply within a preset duration; and determining the target number of newly added power-on hard disks according to the quota current margin and the maximum starting current of the single hard disk, and powering on the non-power-on hard disks. According to the scheme provided by the embodiment of the invention, the power supply capacity of the power supply is fully utilized; the target number is determined according to the quota current margin, then the unpowered hard disk is started, power supply overcurrent protection or damage caused by hard disk starting current impact is avoided, the total starting time of the hard disk can be shortened under the condition thatthe power supply capacity of the power supply is limited, and the efficiency of the power supply is improved.
Description
technical field [0001] The present application relates to the field of storage technologies, and in particular, to a hard disk power-on control method and device. Background technique [0002] The continuous increase of storage business volume requires higher and higher capacity of storage devices. There are two ways to increase storage capacity, one is to increase the storage capacity of a single disk, and the other is to increase the number of hard disks, such as setting up hard disk arrays, etc. Regardless of the solution, the total power consumption of the hard disk will increase. [0003] Since the current of the hard disk is 2 to 3 times the current during normal operation, if all the hard disks are powered on at the same time, the huge current may cause the hard disk power supply to trigger the overcurrent protection. If there is no limit Improving the output current capability of the hard disk power supply will result in a higher cost of the whole machine. [0004]...
