Power-on and power-off control method for hard disk of server, control device and control equipment

Abstract

The invention discloses a power-on and power-off control method for a hard disk of a server. The method comprises the following steps of by pre-setting corresponding relations between the type of index information of the hard disk and a calculation rule, calling the calculation rule according to the type of the index information of a to-be-processed hard disk, calculating position information of the to-be-processed hard disk according to the index information of the to-be-processed hard disk, generating a control command according to the position information of the to-be-processed hard disk and the processing content of the to-be-processed hard disk; finally, according to the position information of the to-be-processed hard disk, writing the control command into a corresponding controller.A user only needs to input the index information and the processing content of the to-be-processed hard disk to realize power-on or power-off control of the to-be-processed hard disk without tediouscalculation, so that the operation of power-on and power-off control of the hard disk is simplified, and the problem of power-on and power-off failure of the hard disk caused by calculation errors ofthe user is avoided. The invention further discloses a server hard disk power-on and power-off control device, control equipment and a computer readable storage medium, which have the above beneficialeffects.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to a control method for powering on and off a hard disk of a server, a control device, a control device, and a computer-readable storage medium. Background technique [0002] With the development and progress of server technology, some servers will have dozens of large-capacity hard disks used to store a large amount of data, and the power consumption of each hard disk is generally about 12 watts. It can be seen that in data storage servers , The power consumption of the hard disk accounts for most of the power consumption of the whole machine. When the server is running, if a certain hard disk fails and cannot be used normally, it is necessary to power off the faulty hard disk without affecting the use of other hard disks, so as to achieve the purpose of energy saving. After the faulty hard disk is replaced, the replacement hard disk needs to be powered on. [0003] The h...

Problems solved by technology

Since different CPLDs may be on different I2C buses, and each register that controls hard disk power on and off in different CPLDs controls the power on and off of hard disks in different slots, when controlling the power on and off of one or some hard disks, the staff It is necessary to determine the location of the hard disk through complex calculations, edit the control command, and then use the i2c-test tool to edit the control command and write the control command into the corresponding register in the corresponding CPLD. electrical failure
