As shown in fig. 3, the main control unit 106 no longer provides GPIO, and the motherboard 102 provides a corresponding SMBus interface 107;
the SMBus interface connects an SMBus type Bus, referred to as System Management Bus (SMBus) 108;
the other end of the SMBus108 is connected with a plurality of Safety controllers (Safety)109 of a communication system power supply;
typically, each security controller 109 is connected to a corresponding RAID disk; if the functions of the security controller 109 are expanded, one security controller 109 may be connected to a plurality of RAID disks.
In the computer system, the RAID card stores the configuration information and the state information of each physical disk of the computer system, the operating system accesses each physical disk through the RAID card to realize access operation, at the moment, the RAID card shields surprisal between the physical disks, so that all the physical disks only appear as a single logical disk in the operating system of the computer system. That is, a computer system includes a common disk for storing data during the operation of the computer system; the backup disk is used for storing backup data of the computer system and providing backup data when data backup is carried out; the main control unit is used for generating and sending a control instruction according to the alarm information or the disk array configuration information from the RAID card and a preset control strategy; the power supply control circuit is used for adjusting the power supply state of the standby disk in the storage equipment according to the control instruction; a control circuit for transmitting the control instruction to the power control circuit; and the communication interface is used for receiving the control instruction and uploading the control instruction to the control circuit.
The RAID card provides different APIs, the main control unit 106 is connected with the RAID card, and the configuration and state information of the RAID card is obtained by calling the APIs; the main control unit 106 generates a control instruction according to the configuration and state information of the RAID card and a predetermined control policy; the control instruction is used for controlling the power-on and power-off of each physical disk.
When a RAID disk of the computer system fails, the main control unit 106 receives a corresponding alarm message. After the control instruction is generated, the control instruction is uploaded to the system management bus108 through the SMBus interface 107, and arrives at the corresponding security controller 109, and according to the control instruction, the security controller 109 controls the physical disk controlled by itself. Because the control instruction is mainly a turn-off instruction and a power-on instruction, when one RAID physical disk cannot be used and data backup needs to be performed by means of the hotspot disk, the RAID physical disk receives the turn-off instruction, and the hotspot disk receives the power-on instruction, the security controller 109 powers on the hotspot disk according to the power-on instruction and performs data backup.
The main control unit 106 generates and sends a working process of the control instruction according to the acquired state information, configuration information, and control policy, as shown in fig. 2, which is specifically described as follows:

Step 205, the BMC checks whether a Hotspare disk still exists through the GPIO, if so, the step 206 is carried out, otherwise, the step 211 is carried out;
at this point, the BMC may also enter an idle waiting state.
For step 204 and step 205, the exchange can be carried out; after the exchange, the BMC acquires configuration information on the RAID card, directly judges whether a HotSpre hard disk exists in the computer system at present, and generates a turn-off instruction if the HotSpre hard disk exists in the computer system; otherwise, go to step 211 to notify the plugging of a new physical hard disk, and execute the step of generating a shutdown instruction after step 211.
And step 206, when the RAID logic disk fails, the RAID card gives an alarm to generate alarm information.
And step 207, the BMC acquires the current alarm information through the provided API.
And step 208, the BMC generates a power-on instruction as a control instruction according to the alarm information and a preset control strategy, the power-on instruction reaches the control circuit switch unit 104 through the GPIO and the control circuit 105, and controls the power-on circuit to power on the Hotspare disk, start and start data backup.
Step 209, after the data backup is finished, a completion signal is returned through the control line 105, and the BMC notifies the replacement of the failed disk.
And step 210, using the replaced fault disk as a new Hotspare disk.
And step 211, the BMC alarms and informs an administrator to plug in a new physical disk as a HotSpare disk. Considering that the current computer is in a normal operation state, the newly plugged hotspot disk may not be powered off temporarily, and the computer is powered off when being started next time, that is, go to step 206;
or, as another preferred embodiment, after the hot spare disk is newly plugged, step 202 may be performed, at this time, the BMC serving as the main control unit 106 in the computer acquires the current configuration information in the RAID card, and performs the subsequent operation.
By applying the technical scheme provided by each preferred embodiment of the invention, the power-on circuit of each disk serving as the common disk and the standby disk can be directly controlled by the main control unit through the control circuit; when any physical disk is used as the hot standby disk, the main control unit can control the power-off and power-on of the hot standby disk, so that the power consumption of the hot standby disk in an idle state can be effectively reduced while data protection is realized, and the total power consumption of the system is effectively reduced.
