Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, on the one hand, the embodiment provides a circuit for controlling independent power on and off of a hard disk, including: a baseboard management controller BMC, a coprocessor, and a hard disk HDD. In this embodiment, the coprocessor is specifically a CPLD chip (Complex Programmable Logic Device, complex programmable logic device). In this embodiment, the baseboard management controller BMC obtains the hard disk status through I2C through the integrated circuit bus, and sends the hard disk status signal to the coprocessor CPLD through the integrated circuit bus through I2C. The co-processor CPLD is used to turn off or turn on the hard disk power supply through the E-fuse control according to the instruction of the baseboard management controller.

[0016] Another aspect of the embodiment provides a method for controll...

Abstract

The embodiment of the invention provides a circuit and a method for controlling the independent power up and down of a hard disk, belonging to the field of server power supply design. The circuit forcontrolling the independent power up and down of the hard disk comprises a substrate management controller, a coprocessor and a hard disk. The substrate management controller is used for acquiring thestate of the hard disk and sending the state signal of the hard disk to the coprocessor. The coprocessor is used for controlling to turn off or turn on the power supply of the hard disk according tothe instruction of the substrate management controller. The embodiment of the invention has the advantages of realizing independent management of hard disk power supply, reducing the power consumptionof the hard disk when the hard disk fails, and improving the stability of the storage system.

Description

technical field [0001] The invention relates to the field of server design, in particular to the design of a hardware power supply circuit. Background technique [0002] With the development of storage technology, in the storage business, the storage capacity is increasing all the time, and the demand for the number of hard disks will also increase; After a fault occurs, the operation and maintenance personnel may not be able to replace the hard disk in time. If the faulty hard disk is always working, it will generate useless power consumption and affect the stability of the machine. Contents of the invention [0003] The invention aims to solve the technical problem of reducing the power consumption generated by the hard disk when a fault occurs. Therefore, the present invention provides a circuit and method for controlling independent power on and off of a hard disk, which has the advantage of being able to reduce the power consumption of the hard disk when the hard dis...
