[0044] In order to make the above-mentioned objects, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0045] Referring to Figure 1 is a step flow chart of an embodiment of a server control method based on an intelligent PDU, the intelligent PDU is connected with a complex programmable logic device (CPLD) of a server mainboard through a serial interface, a preset power consumption value for the server is written in the intelligent PDU, and a power consumption acquisition module is arranged in the server.

[0046] With the development and wide application of computer technology, more and more application systems relying on computer technology have entered the work and life of human beings. At present, the performance of servers has become better and better, but in order to obtain higher performance, multiple servers need to be used to achieve it. The multiple servers can form a computer system, and the computer system formed by the multiple servers is also commonly referred to as a server cluster, so that a group of integrated computer software and / or hardware can be connected to cooperate to complete the computing work. The server cluster is usually used to improve the computing speed and / or reliability of a single server. In general, the power consumption of the server cluster is very large, and therefore the power consumption of the server cluster is usually controlled by an intelligent PDU.

[0047] Among them, the intelligent PDU refers to a power distribution socket for a cabinet. Specifically, the intelligent PDU is a product designed to provide power distribution for cabinet-mounted electrical equipment (such as servers, etc.), has different functions, installation methods, and multiple series specifications with different combinations of plug positions, and can provide suitable cabinet power distribution solutions for different power supply environments. The application of the intelligent PDU can make the power distribution of the servers in the cabinet neat, safe, reliable, professional, and beautiful, and the intelligent PDU can also make the maintenance of the power supply of the servers in the cabinet more convenient and reliable.

[0048] The embodiments of the present application can be applied to an application environment as shown in Figure 2 The server can be a stand-alone server or a server cluster composed of multiple servers. Specifically, the intelligent PDU is connected with the CPLD of the server mainboard through a serial interface, so that the intelligent PDU and the CPLD of the server mainboard can perform corresponding logical conversion and communication through the serial interface, and realize intelligent PDU monitoring power consumption, adjusting power consumption, and realizing server intelligent power-on and power-off and other intelligent functions.

[0049] It should be noted that, since the smart PDU and the CPLD communicate based on a serial interface, even if the network environment is in a paralyzed state, the smart PDU can still be normally used, and the smart function of the smart PDU will not be interrupted by the network environment.

[0050] Of course, the smart PDU can communicate with the CPLD of the server mainboard through a serial interface, or communicate with the CPLD of the server mainboard through a network. Alternatively, the smart PDU can be set to communicate with the CPLD of the server mainboard through both the serial interface and the network, so that even if the network environment is in a paralyzed state, the smart PDU can still communicate with the CPLD of the server mainboard through the serial interface.

[0051] In the embodiment of the application, a voltage and current and power consumption collection module (referred to as a power consumption collection module) is designed for the smart PDU. The power consumption collection module can include a small AC meter head, which has the functions of collecting real-time voltage, real-time current and real-time power consumption of the server, and can feed back the real-time voltage, real-time current and real-time power consumption and other data to the main control RAM (Random Access Memory) board of the smart PDU, so that the main control RAM board can monitor the collected data in real time.

[0052] Specifically, the server control method based on the smart PDU can include the following steps:

[0053] Step 101, receiving a first real-time power consumption value of the server collected by the power consumption collection module.

[0054] In the embodiment of the application, the power consumption collection module can collect the first real-time power consumption value of the server in real time, and feed back the first real-time power consumption value to the main control RAM board of the smart PDU, so that the main control RAM board can determine whether the power consumption of the server needs to be adjusted according to the first real-time power consumption value. When the power consumption needs to be adjusted, the preset power consumption value to be adjusted is written into the main control RAM board of the smart PDU, and the main control RAM board compares and judges the real-time power consumption value collected by the AC meter head at present with the preset power consumption value after receiving the preset power consumption value, to control the server to adjust its power consumption, for example, to increase or decrease the power consumption of the server.

[0055] Step 102, when detecting that the preset power consumption value is lower than the first real-time power consumption value, sending a response of reducing power consumption of the server to the CPLD through the serial interface to control the server to perform frequency reduction operation, and continuing to receive the second real-time power consumption value of the server collected by the power consumption collection module in the process of the server performing frequency reduction operation, if the preset power consumption value is equal to the second real-time power consumption value, sending a response of stopping reducing power consumption of the server to the CPLD through the serial interface to control the server to stop performing frequency reduction operation.

[0056] Specifically, the server includes an ME chip (Intel Management Engine) and a CPU (Central Processing Unit), wherein the ME chip is an embedded microcontroller located in a PCH (Platform Controller Hub) chipset, which runs management firmware by using resources invisible to the server to provide specific management functions.

[0057] Specifically, when the preset power consumption value is lower than the first real-time power consumption value collected by the AC meter head, the main control RAM board of the intelligent PDU communicates with the CPLD chip of the mainboard and informs the CPLD that the response of reducing the power consumption of the whole machine is needed. After the CPLD receives the response of reducing the power consumption of the whole machine, the CPLD communicates with the ME chip of the mainboard through the bus mode, the ME chip communicates, informs the CPU that the frequency reduction operation is needed, the CPU receives the information and performs the active dynamic frequency reduction operation, and the CPU peripheral circuit performs the corresponding dynamic adjustment of voltage and current.

[0058] It should be noted that while the server is performing dynamic adjustment of the power consumption of the whole machine, the AC meter head will continue to collect the second real-time power consumption value of the server, and the main control RAM board compares the second real-time power consumption value collected by the AC meter head in real time with the preset power consumption value, so as to realize the negative feedback of power consumption adjustment. Specifically, when the main control RAM board monitors that the second real-time power consumption value collected by the AC meter head is the same as the preset power consumption value, it will feedback the communication of stopping power consumption reduction to the CPLD, the CPLD receives it and communicates with the mainboard ME chip, the ME chip receives the information and notifies the CPU, so that the CPU stops the response of frequency reduction operation and the voltage and current of the CPU peripheral circuit stop dynamic adjustment.

[0059] Step 103, when detecting that the preset power consumption value is higher than the first real-time power consumption value, sending a response of increasing power consumption of the server to the CPLD through the serial interface to control the server to perform the overclocking operation, and continuing to receive the third real-time power consumption value of the server collected by the power consumption collection module in the process of the server performing the overclocking operation, and if the preset power consumption value is equal to the third real-time power consumption value, sending a response of stopping increasing power consumption of the server to the CPLD through the serial interface to control the server to stop performing the overclocking operation.

[0060] Specifically, when the preset power consumption value is higher than the first real-time power consumption value collected by the AC meter head, the main control RAM board of the intelligent PDU communicates with the CPLD of the mainboard and informs the CPLD that the response of increasing the power consumption of the whole machine is needed. After the CPLD receives the response of increasing the power consumption of the whole machine, the CPLD communicates with the ME chip of the mainboard through the bus mode, the ME chip communicates with the CPU, and informs the CPU that the overclocking operation is needed. After the CPU receives the information, the CPU performs the active dynamic overclocking operation, and the CPU peripheral circuit performs the corresponding dynamic adjustment of voltage and current.

[0061] It should be noted that while the server is performing the dynamic adjustment of the whole machine power consumption, the AC meter head will continue to collect the third real-time power consumption value of the server, and the main control RAM board compares the third real-time power consumption value collected by the AC meter head in real time with the preset power consumption value, so as to realize the negative feedback of power consumption adjustment. Specifically, when the main control RAM board monitors that the third real-time power consumption value collected by the AC meter head is the same as the preset power consumption value, it will feedback the communication of stopping the power consumption increase to the CPLD, and the CPLD receives the response and communicates with the ME chip of the mainboard. The ME chip receives the information and notifies the CPU, so that the CPU stops the response of the overclocking operation and the voltage and current of the CPU peripheral circuit stop the dynamic adjustment.

[0062] Of course, if the preset power consumption value is consistent with the first real-time power consumption value collected by the AC meter head, that is, the preset power consumption value is the same as the first real-time power consumption value collected by the AC meter head, the main control RAM board of the intelligent PDU can not make any response.

[0063] In an optional embodiment of the present application, the intelligent PDU can be provided with a plurality of solid-state relays for realizing multi-path power input and output, and each power input end of the solid-state relays is provided with a corresponding threshold fuse.

[0064] In a specific implementation, as a carrier for power switching, the smart PDU first needs to implement the power switching function. The smart PDU can use a solid-state relay with reliable quality as the power switching. The main control RAM board can control the control end of the solid-state relay through a low-voltage circuit to control the alternating current. The entire smart PDU can preset multiple solid-state relays to realize the function of multiple PDU power input and output. At the same time, in order to prevent overcurrent problems, an appropriate threshold fuse is needed at the power input end of each solid-state relay to ensure safety.

[0065] In an optional embodiment of the present application, the method can further include the following steps:

[0066] When the server is powered off, the smart PDU sends a power-off response to the CPLD to control the power chip of the server to disconnect the direct current of the server, and receives the power-off state of the power chip fed back by the CPLD that the direct current is powered off.

[0067] Specifically, when the server needs to be powered off, the main control RAM board of the smart PDU sends a power-off response to the CPLD. After receiving the response, the CPLD controls the power chip IC (Integrated Circuit Chip) to disconnect the direct current on the mainboard (such as 3.3V, 12V, 5V, etc.) through the logic of the power-off sequence. At the same time, the power chip IC will feed back the power-off state of the direct current to the CPLD, and the CPLD can feed back the power-off state of the direct current to the main control RAM board of the smart PDU. When the direct current of the server is powered off, the power-off process of the server is completed.

[0068] In an optional embodiment of the present application, the method can include the following steps:

[0069] When the server is powered on, the smart PDU sends a power-on response to the CPLD to control the power chip of the server to connect the direct current of the server, and receives the power-on state of the power chip fed back by the CPLD that the direct current is powered on.

[0070] Specifically, when the server needs to be powered on, the main control RAM board of the smart PDU sends a power-on response to the CPLD. After receiving the response, the CPLD controls the power IC to power on the direct current on the mainboard through the logic of the power-on sequence. At the same time, the power chip IC will feed back the power-on state of the direct current to the CPLD, and the CPLD can feed back the power-off state of the direct current to the main control RAM board of the smart PDU. When the direct current of the server is powered on, the power-on process of the server is completed.

[0071] In an optional embodiment of the present application, the intelligent PDU is provided with a speed-adjustable fan, and the cabinet of the intelligent PDU is provided with an air inlet and an air outlet, and the air inlet and the air outlet are provided with temperature sensors, and the method further comprises:

[0072] receiving the real-time temperature sent by the temperature sensors;

[0073] adjusting the fan speed of the speed-adjustable fan according to the real-time temperature.

[0074] When the intelligent PDU is working, the temperature will rise, in order to ensure the normal work of the intelligent PDU, the speed-adjustable fan is arranged on the intelligent PDU. Specifically, the cabinet of the intelligent PDU is provided with an air inlet and an air outlet, and the air inlet and the air outlet are provided with temperature sensors for detecting the real-time temperature of the intelligent PDU in real time and sending it to the intelligent PDU, and the intelligent PDU can adjust the fan speed of the speed-adjustable fan according to the real-time temperature, so as to ensure that the temperature is not too high to cause the intelligent PDU to work abnormally.

[0075] In an optional embodiment of the present application, the main control RAM board of the intelligent PDU is provided with a heat sink for wall-mounted heat dissipation.

[0076] Optionally, in order to further ensure that the temperature of the main control RAM board of the intelligent PDU is not too high, a heat sink can also be arranged on the main control RAM board of the intelligent PDU, so that the main control RAM board can realize wall-mounted heat dissipation.

[0077] As can be seen from the above, the intelligent PDU of the embodiments of the present application is connected with the CPLD of the server mainboard through a serial port interface, so that even when the network environment is in a paralyzed state, the intelligent PDU can still realize its own intelligent functions, such as monitoring the power consumption state of the server, controlling the power-on and power-off state of the server cluster, and the like.

[0078] In order for those skilled in the art to better understand the embodiments of the present application, the following will be described with a complete example.

[0079] The embodiments of the present application design a new intelligent PDU, which is connected with the CPLD of the server mainboard through a serial port interface, so that the intelligent PDU can perform corresponding logical conversion and communication with the CPLD of the server mainboard through serial communication, realize intelligent functions such as monitoring power consumption, adjusting power consumption, power-on, power-off, and the like, so that even when the network environment is in a paralyzed state, the intelligent functions of the intelligent PDU will not be affected.

[0080] Reference Figure 3Fig. 1 is a flow diagram of a server control process based on the intelligent PDU according to the present application. The intelligent PDU is designed in terms of a main control board, heat dissipation, power supply, structure and interface. The design of each part of the intelligent PDU is described in detail below.

[0081] (I) Main control board design

[0082] The main control board is described in terms of four functional modules: PDU power input and output module, voltage, current and power consumption collection module, power consumption adjustment module and control server power on and off module.

[0083] 1. PDU power input and output module

[0084] The intelligent PDU is a carrier for power conversion. The first function to be implemented is power conversion. The intelligent PDU can use a reliable solid-state relay for power conversion. The main control RAM board can control the control end of the solid-state relay through a small voltage circuit to control the alternating current. The intelligent PDU can be pre-set with multiple solid-state relays to achieve the function of multiple PDU power input and output. In order to prevent overcurrent, an appropriate threshold fuse is pre-set at the power input end of each solid-state relay to ensure safety.

[0085] 2. Voltage, current and power consumption collection module

[0086] The voltage, current and power consumption collection module can be pre-set with a small AC meter at the output end of the solid-state relay. The AC meter has the function of collecting real-time voltage, real-time current and real-time power consumption, and feeds back the voltage, current and power consumption to the main control RAM board of the intelligent PDU. The main control RAM board monitors the collected data in real time.

[0087] 3. Power consumption adjustment module

[0088] When the power consumption needs to be adjusted, the pre-set power consumption value to be adjusted is written into the main control RAM board. After the main control RAM board receives the pre-set power consumption value, the main control RAM board compares the real-time power consumption collected by the AC meter with the pre-set power consumption value and makes a judgment.

[0089] When the preset power consumption value is lower than the real-time power consumption value collected by the AC meter, the main control RAM board of the intelligent PDU communicates with the CPLD chip of the main board and informs the CPLD that the response of reducing the power consumption of the whole machine is needed. After the CPLD receives the response of reducing the power consumption of the whole machine, the CPLD communicates with the ME chip of the main board through the bus mode, the ME chip communicates with the CPU, and informs the CPU that the frequency reduction operation is needed. After the CPU receives the information, the CPU performs the active dynamic frequency reduction operation, and the CPU peripheral circuit performs the dynamic adjustment of the voltage and current. In addition, the main control RAM board compares the real-time power consumption value collected in real time with the preset power consumption value, so as to realize the negative feedback of the power consumption adjustment. Specifically, when the main control RAM board monitors that the real-time power consumption value continuously collected by the AC meter is the same as the preset power consumption value, the communication of stopping the power consumption reduction is fed back to the CPLD, the CPLD communicates with the ME chip of the main board after receiving, the ME chip receives the information and informs the CPU, so that the CPU stops the response of the frequency reduction operation and the voltage and current of the CPU peripheral circuit stop the dynamic adjustment.

[0090] When the preset power consumption value is higher than the real-time power consumption value collected by the AC meter, the main control RAM board of the intelligent PDU communicates with the CPLD of the main board and informs the CPLD that the response of increasing the power consumption of the whole machine is needed. After the CPLD receives the response of increasing the power consumption of the whole machine, the CPLD communicates with the ME chip of the main board through the bus mode, the ME chip communicates with the CPU, and informs the CPU that the frequency increase operation is needed. After the CPU receives the information, the CPU performs the active dynamic frequency increase operation and the CPU peripheral circuit performs the dynamic adjustment of the voltage and current. In addition, the main control RAM board compares the real-time power consumption value collected in real time with the preset power consumption value, so as to realize the negative feedback of the power consumption adjustment. Specifically, when the main control RAM board monitors that the real-time power consumption value continuously collected by the AC meter is the same as the preset power consumption value, the communication of stopping the power consumption increase is fed back to the CPLD, the CPLD communicates with the ME chip of the main board after receiving, the ME chip receives the information and informs the CPU, so that the CPU stops the response of the frequency increase operation and the voltage and current of the CPU peripheral circuit stop the dynamic adjustment.

[0091] When the preset power consumption value is the same as the real-time power consumption value collected by the AC meter, the main control RAM board of the intelligent PDU does not respond, and of course the CPLD does not need to respond.

[0092] 4. Power on and off function of control server

[0093] When the server needs to be powered off, the main control RAM board of the intelligent PDU sends a power-off response to the CPLD. After receiving the response, the CPLD controls the power IC to disconnect the DC power on the mainboard (such as 3.3V, 12V, 5V, etc.) through the logic of the power-off sequence.
