Problems solved by technology
In many systems, multiple SATA hard disks are installed at the same time. When the system is turned on, all the SATA hard disks will draw a large instantaneous current at the same time. However, when the SATA hard disk is working, the required operating current is significantly less than the starting current. Configuring a high-power power supply for the server will cause low power utilization when the server is running normally, and the cost of high-power power supply is relatively high. For the above problems, the existing solution is to sequentially start the hard disks in the server hard disk group However, in some cases, the start-up current of the hard disk group is not higher than the current threshold of the power supply. If the hard disk group is still started sequentially, it will waste a certain amount of time

Embodiment Construction
[0013] Please refer to figure 1 A preferred embodiment of the hard disk boot control circuit 10 of the present invention includes a power supply 20 , a detection unit 30 , a control unit 40 and a hard disk group 50 .
[0014] The power supply 20 is connected to the hard disk group 50 through the detection unit 30 , and the detection unit 30 is also connected to the hard disk group 50 through a control unit 40 .
[0015] When in use, the power supply 20 supplies power to the hard disk group 50, the detection unit 30 detects the output current of the power supply 20, and compares the detected current value with a preset value. If the current value is less than or equal to the preset value, the hard disk group 50 will start normally, that is, the hard disks in the hard disk group 50 will start at the same time; if the detected current value is greater than the preset value, the detection unit will 30 will output a trigger signal to the control unit 40, and the control unit 40 wi...

A hard disk starting control circuit comprises a power supply, a detection unit and a control unit. The power supply is used for supplying power for a hard disk cluster of a server, and the hard disk cluster comprises a plurality of hard disks. The detection unit detects a current value output by the power supply and outputs a trigger signal if the current value is larger than a preset value. The control unit is respectively connected with the detection unit and the hard disk cluster and outputs a control signal and controls the hard disks in the hard disk cluster to be started in a preset sequence when receiving the trigger signal. The control unit controls the hard disk cluster to be started in sequence so as to avoid abnormal power supply work caused by an overlarge current peak value.
Description
technical field [0001] The invention relates to a hard disk startup control circuit. Background technique [0002] At present, SATA hard disks have been widely used in systems using hard disks, such as computers and servers, and have the advantages of fast transmission speed and hot swappability. In many systems, multiple SATA hard disks are installed at the same time. When the system is turned on, all the SATA hard disks will draw a large instantaneous current at the same time. However, when the SATA hard disk is working, the required operating current is significantly less than the starting current. Configuring a high-power power supply for the server will cause low power utilization when the server is running normally, and the cost of high-power power supply is relatively high. For the above problems, the existing solution is to sequentially start the hard disks in the server hard disk group However, in some cases, the start-up current of the hard disk group is not highe...
