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...
