Problems solved by technology

During the operation of the server, due to vibration, connector aging and other reasons, the power supply connector on the mainboard or backplane side is prone to poor contact with the power supply line, resulting in unstable power supply voltage of the hard disk. Once the voltage is lower than the hard disk requirements threshold, it will cause the hard disk to stop working, and even cause data loss

Description

technical field [0001] The invention relates to the field of servers, in particular to a power supply control circuit, a server hard disk backplane and a power supply circuit thereof. Background technique [0002] The hard disk backplane is an important part of the server system. It is used to connect the hard disk and provide the power output for the hard disk. Power supply is a necessary condition for the hard disk to work normally. If the power supply is abnormal during the hard disk operation, the hard disk will stop working, and the data stored in the hard disk will be at risk of loss. Therefore, ensuring the stable and reliable power supply of the hard disk backplane is the key to ensuring data security. [0003] The current server hard disk backplane power supply method usually uses a power supply cable with one end connected to the motherboard power supply connector and the other end connected to the hard disk backplane power supply connector, and the power supply o...
