Description
Technical Field
The invention relates to the technical field of servers. The invention further relates to a server temperature redundancy control method and device.
Background
Temperature control has always been a great proposition in the field of servers. Currently, the x86 servers used in the industry are basically Intel to provide technical support, most CPUs are also from Intel manufacturers, and some designs such as architectural design and board bus are also designed and used by Intel. Therefore, currently, each server design company sets different heat dissipation modes, such as air cooling, water cooling, mixed heat dissipation and the like, according to the Intel temperature specification. Among the components of the X86 architecture platform, the CPU (Central Processing Unit) typically consumes the most power and the temperature is the highest. There are different processing modes for the control part of this part. Specifically, in the existing design scheme of the motherboard in the server, a PCH (Platform Control unit) is generally adopted to obtain temperature information of the CPU through a PECI (Platform Environment Control Interface) bus, and then the temperature information of the CPU is transmitted to a BMC (Baseboard Management Controller) through an SMLINK bus (or SMBus), and after receiving the transmitted CPU temperature information, the BMC directly controls a fan PWM (Pulse width modulation) signal to Control the rotation speed of the fan.
Generally, 1 piece of PCH and BMC are placed on a motherboard, and two paths of servers are used for illustration, and a general motherboard is equipped with 2 CPUs, 1 piece of PCH, 1 piece of BMC, and 1 piece of CPLD (Complex Programmable Logic Device), which are related devices for controlling a main fan. When there is a problem with the PCH and/or BMC on the motherboard, for example, when the BMC is down and cannot execute the current setting, how to ensure that the fan control is normal needs to be considered. In the current temperature control, the temperature control modes under the condition that the SMLINK of the PCH is hung up and under the condition that the BMC is hung up are not considered, so that the fan control is in an uncontrolled state under the two abnormal conditions.
Therefore, a solution to the problem of uncontrolled heat dissipation in the server when a chip failure occurs in the PCH and/or BMC or a firmware problem occurs is needed, so as to better regulate the temperature in the server and further protect the safe operation of the server.

Detailed Description
While the present invention may be embodied in various forms, there is shown in the drawings and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiments illustrated.
It should be noted that the steps mentioned in the following description of the embodiments of the present invention are only numbered for convenience and clarity of indicating the steps without specific description, and do not limit the sequence of the steps.
In order to solve the problem of uncontrolled heat dissipation in a server when a chip failure or a firmware occurs in a PCH (Platform control unit) and/or BMC (Baseboard Management Controller), the present invention provides a method for redundant control of server temperature. Fig. 1 shows a schematic block diagram of an embodiment of a method of server temperature redundancy control according to the present invention. In the embodiment shown in fig. 1, the method comprises at least the following steps:
s1: the control channel selector transmits the collected first temperature to the first controller by a first channel, and performs first temperature control based on the first temperature by the first controller, the second controller and the third controller which are connected in serial communication;
s2: monitoring a first bus and a feed dog signal between a second controller and a third controller;
s3: in response to the first bus being idle for more than a threshold time and the dog feed signal being normal, controlling the channel selector to communicate the first temperature to the second controller in the second channel and to perform a second temperature control by the second controller and the third controller based on the first temperature;
s4: in response to the first bus being idle for more than a threshold time and the dog feed signal being abnormal, the channel selector is controlled to communicate the first temperature to the third controller in a third channel, and third temperature control is performed by the third controller based on the first temperature.
An embodiment of the method is described in detail below with reference to fig. 2. First, by default, that is, when the server system is operating normally, step S1 controls the channel selector 10 to transmit the first temperature to the first controller 20 in the first channel 11, and the first temperature control is performed by the first controller 20, the second controller 30, and the third controller 40 connected in serial communication based on the first temperature. The first temperature is preferably the collected temperature of the server CPU. In some embodiments, this step implements a conventional server temperature control strategy. In a preferred embodiment, this first temperature control further adds a multi-faceted temperature regulation strategy to the conventional server temperature control strategy, as will be further explained below. During server operation, step S2 monitors the first bus 50 and the dog feed signal 60 between the second controller 30 and the third controller 40. Preferably, the first bus 50 and the watchdog signal WDT (abbreviation for watchdog) 60 are monitored by the third controller 40. When the first bus 50 is idle for more than the threshold time and the dog feeding signal 60 is normal, it is considered that the first controller 20 is abnormal and cannot operate, so step S3 controls the channel selector 10 to transmit the first temperature to the second controller 30 through the second channel 12, and the second controller 30 and the third controller 40 perform the second temperature control based on the first temperature. In a preferred embodiment, this second temperature control further adds a multi-faceted temperature regulation strategy to the conventional server temperature control strategy, as will be further explained below. When the second bus 50 is idle for more than the threshold time and the dog feeding signal 60 is abnormal, it is considered that the first controller 20 and the second controller 30 or the second controller 30 is abnormal and cannot operate, so step S4 controls the channel selector 10 to transmit the first temperature to the third controller 40 through the third channel 13, and the third controller 30 performs the third temperature control based on the first temperature. Since the operating frequencies of the first controller 20, the second controller 30, and the third controller 40 used in the server are relatively high, the threshold time is usually set to be short, preferably in milliseconds, and at least cannot exceed seconds, in order to ensure the stability of the server temperature control.
In some embodiments of the server temperature redundancy control method of the present invention, the step S1 controlling the channel selector 10 to transfer the collected first temperature to the first controller 20 in the first channel 11, and performing, by the first controller 20, the second controller 30, and the third controller 40 connected in serial communication, the first temperature control based on the first temperature further comprises:
s11: the first controller analyzes the first temperature, regulates and controls the working state of the CPU according to the analyzed first temperature, and forwards the analyzed first temperature to the second controller through the second bus;
s12: the second controller generates a control instruction according to the analyzed first temperature and the collected second temperature, and sends the control instruction to the third controller through the first bus;
s13: and the third controller outputs a fan control signal according to the control instruction.
The specific control strategy for the first temperature control proposed in these embodiments is specifically described below, i.e., a temperature regulation strategy is added to the conventional server temperature control strategy in many aspects. After controlling the channel selector 10 to transmit the first temperature to the first controller 20 through the first channel 11, first, the first controller 20 parses the first temperature, and adjusts the CPU operating state according to the parsed first temperature, and forwards the parsed first temperature to the second controller 30 through the second bus 70 in step S11. Based on the parsed first temperature, the first controller 20 issues a corresponding instruction to adjust the operating state of the CPU, such as reducing the operating frequency of the CPU, adjusting the data processing intensity of the CPU, and so on, thereby fundamentally controlling the temperature of the CPU. At the same time, the first controller 20 forwards the parsed first temperature to the second controller 30 through the second bus 70, thereby allowing the second controller 30 to further control the server temperature. Then, in step S12, the second controller 30 generates a control command based on the analyzed first temperature and the collected second temperature, and transmits the control command to the third controller 40 via the first bus 50. From another perspective, in the first temperature control, the second controller 30 is a core control part of the server temperature control, and the second controller 30 generates a corresponding control command according to the resolved first temperature forwarded by the first controller 20 and comprehensively considering a second temperature collected by the second controller 30 through another interface (for example, the general purpose input output interface GPIO). The second temperature referred to herein includes the temperature of other elements, locations, in the server other than the CPU. After the second controller 30 generates the control command, the control command is transmitted to the third controller 40 through the first bus 50. Finally, in step S13, the third controller 40 outputs a FAN control signal, preferably a PWM FAN control signal, according to the control command, and directly outputs the FAN control signal to the FAN (FAN)80 to perform real-time temperature control on the server. In another aspect, the third controller 40 is essentially operating as an actuator for the second controller 30 in the first temperature control.
In some embodiments of the method of server temperature redundancy control of the present invention, the step S3 controlling the channel selector 10 to communicate the first temperature to the second controller 30 in the second channel 12 in response to the first bus 50 being idle for more than a threshold time and the dog feeding signal 60 being normal, and performing, by the second controller 30 and the third controller 40, the second temperature control based on the first temperature further comprises:
s31: the second controller analyzes the first temperature, generates a control instruction according to the analyzed first temperature and the collected second temperature, and sends the control instruction to the third controller through the first bus;
s32: and the third controller outputs a fan control signal according to the control instruction.
The specific control strategy of the second temperature control proposed in these embodiments is specifically described below. At this time, the first controller 20 is considered to be abnormal and thus cannot operate, that is, the first controller 20 cannot provide the aforementioned function of analyzing and forwarding the first temperature. Therefore, the control channel selector 10 transmits the first temperature to the second controller 30 through the second channel 12, and the second controller 30 provides a function of resolving the first temperature, that is, the second controller resolves the first temperature in step S31, and generates a control command according to the resolved first temperature and the collected second temperature, and transmits the control command to the third controller 40 through the first bus 50. In the second temperature control, the second controller 30 serves as the only control part of the server temperature control, and the second controller 30 generates a corresponding control command according to the first temperature analyzed by itself and comprehensively considering the second temperature collected by the second controller 30 through other interfaces (for example, the general purpose input output interface GPIO), and sends the control command to the third controller 40 through the first bus 50. Finally, in step S32, the third controller 40 outputs a fan control signal, preferably a PWM fan control signal, according to the control command, and directly outputs the fan control signal to the fan 80, so as to perform real-time temperature control on the server. In another aspect, the third controller 40 is essentially operating as an actuator for the second controller 30 in the second temperature control.
In some embodiments of the method of server temperature redundancy control of the present invention, the step S4 controlling the channel selector 10 to communicate the first temperature to the third controller 40 in the third channel 13 in response to the first bus 50 being idle for more than a threshold time and the dog feed signal 60 being abnormal, and performing, by the third controller 40, a third temperature control based on the first temperature further comprises:
the third controller analyzes the first temperature and outputs a preset fan control signal according to the analyzed first temperature.
The specific control strategy of the third temperature control proposed in these embodiments is specifically described below. At this time, it is considered that both the first controller 20 and the second controller 30 or the second controller 30 is abnormal and is not able to operate, that is, the functions of parsing, forwarding and substantial control are not able to be completed. Therefore, the third controller 40 receives and analyzes the first temperature, and outputs a predetermined fan control signal according to the analyzed first temperature. On the other hand, in the third temperature control, the third controller 40 essentially assumes a substantial control work and performs a work. However, since both the function and the stability cannot be achieved, a control device having sufficiently high stability and slightly poor functionality is generally selected in order to ensure the stability of the third controller. Therefore, some specific control signals, such as full rotation speed PWM, 90% rotation speed PWM, 80% rotation speed PWM, etc., are preset in the third controller 40, and when the first temperature obtained by analysis is within a certain range, the corresponding PWM control signals are output to the fan 80, so that the fan operates at a relatively high rotation speed, and it is ensured that the temperature in the server is not too high, but the server cannot be subjected to real-time temperature control at this time.
In some embodiments of the method for controlling the temperature redundancy of the server of the present invention, the first Controller 20 is a PCH chip (Platform control unit), the second Controller 30 is a BMC (Baseboard Management Controller), and the third Controller 40 is a CPLD (Complex Programmable Logic Device). The PCH can analyze the first temperature, and can adjust and control the operating state of the CPU while forwarding the analyzed first temperature. The BMC can better assume the actual control effort as a second controller. The CPLD has sufficient stability and certain control functions. The BMC chip is generally an advanced AST2500 chip or other similar management chip, and mainly analyzes information such as PECI and SMLINK and outputs a dog feeding signal to the CPLD in the present day, and the BMC I2C is mainly used for transmitting fan control information to the CPLD.
In some embodiments of the server temperature redundancy control method of the present invention, the first Bus 50 is an I2C Bus (Inter-Integrated Circuit Bus). That is, the second controller 30 and the third controller 40 are communicatively connected via an I2C bus to transmit control commands. Additionally, in some embodiments, the second bus is a SMLINK bus (or SMBus, system management bus). That is, the first controller 20 and the second controller 30 are communicatively connected via the SMLINK bus to communicate the resolved first temperature.
In some embodiments of the server temperature redundancy control method of the present invention, the channel selector 10 is a GPIO (General Purpose Input/Output) channel switching chip, and the channel selector 10 is controlled by the third controller 40 to gate the first channel 11, the second channel 12, or the third channel 13. A GPIO channel switching chip, that is, an I/O-SW (Input/Output Switch) chip refers to a GPIO switching chip, generally 2 pins are set for selecting a channel, that is, a channel can be selected by setting a level state of the 2 pins, so that switching to 3 channels is possible. And, since the stability of the third controller 40 is strongest, the channel selector 10 is controlled by the third controller 40 to gate the first channel 11 or the second channel 12 or the third channel 13 according to the Select signal. The Select signal refers to a channel switching control GPIO of the I/O-SW chip, and is generally 2 GPIOs, which are used to control the I/O-SW chip to switch to different channels.
In some embodiments of the method of server temperature redundancy control of the present invention, the dog feeding signal is normally a constant frequency square wave. The BMC generally outputs a square wave with fixed frequency to the CPLD for feeding back whether the working state of the BMC is normal or not. Preferably, a constant frequency of 1Hz is selected to facilitate monitoring by the third controller 40.
The hardware link and the elements in the hardware link in fig. 2 are taken as examples to further illustrate the method of the present invention.
By adopting two server mainboards for example, the PECI buses of two CPUs are connected to an I/O-SW chip (a chip of a GPIO switching channel), the PCH, the BMC and the CPLD are also connected to the I/O-SW chip, the CPU temperature information is transmitted between the PCH and the BMC through the SMLINK, a dog feeding signal WDT (abbreviation of watch dog) is interconnected between the BMC and the CPLD, and an I2C channel is arranged between the BMC and the CPLD and used for transmitting fan control information.
The normal fan control flow is as follows: the CPU1 and the CPU2 transmit the temperature information of the two CPUs respectively through the PECI bus, and the I/O SW chip is provided with a select control pin for switching the channel of the I/O SW chip. The channel of the I/O SW is generally set: CH 1: PCH terminal, CH 2: BMC end, CH 3: and a CPLD end. The default setting I/O SW channel is switched to CH1, namely, the I/O SW channel is connected to the PCH end, so that the PECI bus of the CPU transmits temperature information to the PCH end, the PCH end receives PECI bus data, analyzes the PECI bus data, and transmits corresponding data to the BMC through the SMLINK bus, and therefore the temperature information transmission from the CPU to the BMC is completed. After receiving the temperature information, the BMC sends a control instruction to the CPLD according to the set temperature and rotating speed to perform PWM control, namely fan rotating speed control. The above is the fan control flow under normal conditions.
Since the PECI is mainly transmitted to the ME module of the PCH, and the module is responsible for managing the power supply and other functions of the PCH, when the module fails, the PECI signal cannot be analyzed, that is, the temperature information of the CPU cannot be transmitted. According to the normal flow, the BMC is responsible for acquiring temperature information from the PCH through the SMLINK bus, cannot acquire the temperature information and cannot transmit the temperature information to the CPLD through the I2C, and finally the fan is controlled to be invalid and is in an out-of-control state.
When the PCH is normal, the BMC has a fault, and at this time, even if the SMLINK normally transmits temperature information, the BMC is in a hang-up state, the BMC cannot transmit information to the CPLD, and the fan is also in an out-of-control state.
When the CPLD detects that no data transmission of I2C reaches a set threshold time, and detects that a WDT (dog feeding signal) is in a normal state, it may be considered that the PCH fault is currently determined and the BMC is normal, which is a no-fan control state. At this time, the CPLD controls the I/O SW chip through a select pin, and switches to channel 2(CH 2): and at the BMC end, the BMC is responsible for analyzing the PECI, and after analysis, the PECI is transmitted to the CPLD through I2C according to a fan regulation strategy, and the CPLD carries out PWM output to control the rotating speed of the fan.
When the CPLD detects that no data transmission of I2C reaches a set threshold time, and detects that a WDT (dog feeding signal) is abnormal, it may be considered that both the PCH and the BMC are currently in a fault, and it is in a fanless control state. At this time, the CPLD controls the I/O SW chip through select pin, and switches to channel 3(CH 3): and the CPLD is responsible for the analysis of the PECI, and directly carries out PWM output and controls the rotating speed of the fan according to a fan regulation and control strategy after the analysis.
Therefore, the fan can be regulated and controlled no matter the PCH fault or the BMC fault or both the PCH and the BMC fault is ensured, and the temperature control in the server is ensured.
In another aspect, the present invention further provides a device for controlling temperature redundancy of a server, wherein the device includes: at least one processor; and a memory storing program instructions executable by the processor to perform the steps of any one of the foregoing embodiments of a method of server temperature redundancy control when executed by the processor.
