Because each power supply unit can only provide power to the corresponding computer node, when the power supply unit is abnormal or stops operating so as not to provide power to the corresponding computer node, the computer node stops operating due to lack of power supply.
However, computer server systems often require the cooperation of multiple computer nodes to perform complex tasks; if the computer node corresponding to the power supply unit cannot operate due to the failure of the power supply unit, the stability and the working efficiency of the system are greatly reduced.
Accordingly, the present invention provides a power supply method for a computer system, which can support power among computer nodes.

FIG. 1 is a block diagram illustrating a computer system implementing the power supply method for the computer system of the present invention.
FIG. 2 is a flowchart illustrating an embodiment of a power supply method for a computer system according to the present invention.
[ detailed description ] A
Referring to fig. 1, the power supply method for a computer system according to the present invention is implemented by a computer system, which includes a first computer node 1, a first power supply module 2 corresponding to the first computer node 1, a second computer node 3, a second power supply module 4 corresponding to the second computer node 3, and a connection module 5. Here, the computer system is a rack server system (rack server system), and the connection module 5 is a rack backplane.
The first computer node 1 includes a first board management controller 11 (baseboard management controller), and a first CPU 12 and a first voltage regulator 13 (voltage regulator) electrically connected to the first baseboard management controller 11. The second computer node 3 comprises a second baseboard management controller 31, and a second CPU 32 and a second voltage regulator 33 electrically connected to the second baseboard management controller 31. The first baseboard management controller 11 and the second baseboard management controller 31 can monitor the first CPU 12 and the second CPU 32 respectively to generate a corresponding first monitoring message and a corresponding second monitoring message, wherein the first monitoring message and the second monitoring message respectively indicate whether the first CPU 12 and the second CPU 32 are operating normally.
In addition, the first BMC 11 and the second BMC 31 can monitor the first voltage regulator 13 and the second voltage regulator 33, respectively, to generate a first power demand message and a second power demand message corresponding to the first voltage regulator 13 and the second voltage regulator 33, respectively, wherein the first power demand message and the second power demand message indicate the amount of power required by the first computer node 1 and the second computer node 3 to maintain normal operation, respectively.
The first power supply module 2 includes a first power distribution board 21 (power distribution board) and a first power supply unit 22 electrically connected to the first power distribution board 21. The second power supply module 4 includes a second power distribution board 41 and a second power supply unit 42 electrically connected to the second power distribution board 41. The first power distribution board 21 is electrically connected to the first computer node 1 and the connection module 5, and the second power distribution board 41 is electrically connected to the second computer node 3 and the connection module 5. The first power supply unit 22 and the second power supply unit 42 are respectively connected to an ac power source 6, convert ac power into dc power, and transmit the dc power to the first computer node 1 and the second computer node 3 through the first power distribution board 21 and the second power distribution board 41, respectively.
Referring to fig. 1 and fig. 2 together, an embodiment of the power supply method for a computer system according to the present invention is described in detail below, wherein the bmc of each computer node executes steps S1 to S4 shown in fig. 2.
In step S1, the bmc of each computer node detects whether the operation of the power supply unit corresponding to another computer node is abnormal. For example, the first bmc 11 detects whether the second power supply unit 42 can provide dc power through the connection module 5 and the second power distribution board 41; if the second power supply unit 42 cannot provide dc power, the first bmc 11 determines that the second power supply unit 42 is abnormal, otherwise determines that the second power supply unit 42 is normal.
When the bmc of the computer node detects an abnormal operation of the power supply unit of the other computer node, the bmc of the computer node further performs step S2: detecting whether the CPU of the other computer node is operating normally. As described in the above example, when the first bmc 11 detects the operation abnormality of the second power supply unit 42, the first bmc 11 further receives the second monitoring information from the second bmc 31 through the connection module 5, and determines whether the operation of the second cpu 32 of the second computer node 3 is normal according to the second monitoring information.
When the bmc of the computer node detects that the cpu of the other computer node is operating normally, the bmc of the computer node further performs step S3: detecting whether the operation of the power supply unit corresponding to the computer node is normal. As described above, when the first bmc 11 detects that the second cpu 32 is operating normally, the first bmc 11 detects whether the first power supply unit 22 can provide dc power through the first power distribution board 21; if the first power supply unit 22 can provide dc power, the first bmc 11 determines that the first power supply unit 22 is operating normally, otherwise, it is abnormal.
When the baseboard management controller detects that the power supply unit corresponding to the computer node to which the baseboard management controller belongs operates normally, the baseboard management controller further executes step S4 to start a power rescue mechanism, that is, the baseboard management controller controls the power supply unit corresponding to the computer node to which the baseboard management controller belongs to provide power to the other computer node; it should be noted that, under the condition that each power supply unit is operating normally, each power supply unit is independently controlled by the bmc of the corresponding computer node to provide power to the corresponding computer node, and after the power rescue mechanism is started, the power of the computer node corresponding to the power supply unit with abnormal operation is provided by the power supply unit not corresponding to the computer node. As described in the above example, when the first bmc 11 detects that the first power supply unit 22 is operating normally, the first bmc 11 receives the second power demand information from the second bmc 31 through the connection module 5 and determines that the second computer node 3 needs to maintain normal operation, and controls the first power supply unit 22 to increase the power supply amount, so as to maintain stable supply of the power needed by the first computer node 1 to the first computer node 1, and simultaneously provide the power needed by the second computer node 3 to the second computer node 3, wherein the needed power is transmitted to the second computer node 3 through the first power distribution board 21, the connection module 5, and the second power distribution board 41 in sequence.
Although the above description is made by taking the example that the first power supply unit 22 corresponding to the first computer node 1 supports power to the second computer node 3 as an example, it is obvious that when the first power supply unit 22 is abnormal and cannot provide power to the corresponding first computer node 1, the second bmc 31 can also determine whether to control the second power supply unit 42 to support power to the first computer node 1 through the above manner.
That is, if the first power supply unit 22 and the second power supply unit 42 both operate normally, the power rescue mechanism is not activated, and the power supply units only provide power to their corresponding computer nodes, i.e., the first computer node 1 and the second computer node 3. When one of the power supply units is abnormal in operation and cannot provide power, the power rescue mechanism is used for enabling the other power supply unit to increase the power supply amount so as to provide power required by the computer node corresponding to the power supply unit with abnormal operation while maintaining stable power supply required by the computer node corresponding to the power supply unit with abnormal operation, and prevent the computer node corresponding to the power supply unit with abnormal operation from being incapable of normal operation due to lack of power.
In summary, in the power supply method for a computer system according to the present invention, when the bmc of one computer node in the computer system determines that the power supply unit corresponding to another computer node is abnormal and the cpu of the other computer node is normal, the bmc controls the power supply unit corresponding to the computer node to provide power to the other computer node, so as to prevent the other computer node from being unable to operate normally due to the corresponding power supply unit being unable to provide power, thereby solving the technical problem of the present invention.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
