Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a server-collaborative power-on and power-off device, method, system and medium.
In order that those skilled in the art will better understand the disclosure, the following detailed description is given with reference to the accompanying drawings.
In the application of the current server, the resource of the main server is limited, so the resource expansion is performed by the device such as the pooling server. However, since the pooling server cannot work alone, the system can be regarded as a component of the main server, taking a Graphics Processing Unit (GPU) pooling server as an example, when the system is powered on, it is required to first ensure that the GPU pooling server is powered on, and then the main server is powered on, otherwise, the main server cannot identify the PCIE device. When the system is powered off, the main server needs to be ensured to be powered off, then the GPU pooling server is powered off, and otherwise, the system can be down.
PCIE: peripheral Component Interconnect Express, high speed serial computer expansion bus standard.
I2C bus: a simple, bi-directional two-wire synchronous serial bus. It requires only two wires to transfer information between devices connected to the bus.
When the cooperative power-on is carried out, the main server BMC issues a power-on instruction to the pooling server BMC through the I2C bus, polls the power-on state of the pooling server continuously, and executes the power-on operation after the pooling server is powered on. When the power is off, the main server firstly executes the power-off action, the BMC sends the power-off instruction to the pooling server BMC through the I2C after detecting that the main server is off, and the pooling server executes the power-off operation.
Specifically, the power-on and power-off operations to the servers are implemented by Complex Programmable Logic Devices (CPLDs) provided at the respective servers, the CPLD responsible for power-on and power-off of the main server is called a CPLD of the main server, and the CPLD responsible for power-on and power-off of the pooling server is called a CPLD of the pooling server. The CPLD of the main server and the CPLD of the pooling server have no connection relation, and the cooperative power on and power off of the servers are realized through unified allocation of the BMC.
However, the above-mentioned software-based collaborative power-on/power-off scheme may cause abnormal power-on/power-off of the whole server due to BMC abnormality or communication abnormality between two levels of management units, thereby affecting normal operation of the server.
In order to solve the above problem, the present application provides a server cooperating with a power on/off device, as shown in fig. 1, including: a main server CPLD12 provided at the main server 11 and a pooling server CPLD14 provided at the pooling server 13;
the main server CPLD12 is in communication connection with the pooling server CPLD14;
the PWRGD terminals of the power management chips 15 (power management chips a-E) of the remaining components of the main server 11 are connected to the main server CPLD12, and the PWRGD terminals of the power management chips 15 (power management chips a-E) of the remaining components of the pooling server 13 are connected to the pooling server CPLD 14.
PWRGD terminal: also known as PWRGD pin, it outputs a high/low level signal for indicating whether the corresponding device is powered on.
The PWRGD ends of the power management chips 15 of the other components of each server are connected to the corresponding CPLDs and are monitored by the CPLDs, so that the CPLDs can acquire the power-on state of the servers without BMCs (strictly speaking, in the existing architecture, the CPLDs do not need to acquire the power-on state of the servers, and only need to transmit corresponding instructions after acquiring the power-on state, and the CPLDs perform power-on and power-off operations according to the instructions transmitted by the BMCs). In general, taking the master server 11 as an example, the master server 11 is considered to be powered on only when the master server 11 and the rest of the components of the master server 11 are in the powered on state.
In addition, it should be noted that, in this embodiment, the communication connection mode between the main server CPLD12 and the pooling server CPLD14 is not limited, and may be a wired connection or a wireless connection, the used communication protocol is also not limited, and the type of the communication interface is also not limited, which aims to establish the communication connection between the main server CPLD12 and the pooling server CPLD14, so that the two can perform the transmission of the power-on signal and the power-off signal, and the monitoring of the power-on states of the main server 11 and the pooling server 13 without using the BMC.
This example provides a preferred embodiment: the main server CPLD12 and the pooling server CPLD14 establish a communication connection therebetween through a General-purpose input/output (GPIO).
Accordingly, the power-on signal, the power-off signal and the power-on state of each server are all level signals.
In one possible embodiment, the Power-on signal is a PowerCtrl signal that is pressed by the Power button (Power button) or pulled down when the BMC receives a Power-on command, and the Power-off signal is a PowerCtrl signal that is pulled down for 4 seconds when the Power button (Power button) is pressed for 4 seconds or when the BMC receives a Power-off command. That is, the power-on signal is transmitted to pull down the level signal of the corresponding GPIO port, and the power-off signal is transmitted to pull down the level signal of the GPIO port for 4s.
Similarly, the power-on and power-off states of the server may be the same as the PWRGD terminal of the power management chip 15, and whether the server is powered on is represented by different levels, that is, the CPLD performs a pull-down or pull-up operation on the level signal at the corresponding GPIO port.
Through the preferred scheme provided by the embodiment, the pure software-implemented server cooperation power-up and power-down scheme that the conventional BMC sends the instruction through software polling is converted into the hardware-implemented server cooperation power-up and power-down scheme that the CPLD transmits high and low level signals through the GPIO. Compared with the traditional software implementation, the hardware implementation scheme has higher reliability, and is more difficult to cause the server to be incapable of cooperatively powering on and powering off due to faults, so that the use reliability of the server is improved.
Likewise, the present application is not limited to the number of communication connections established between the main server CPLD12 and the pooling server CPLD14, but provides a preferred implementation: the main server CPLD12 and the pooling server CPLD14 are connected through three independent GPIO communications, and are respectively configured to transmit a power-on signal/a power-off signal, a power-on state of the main server 11, and a power-on state of the pooling server 13.
As described in the above embodiments, the power-on/power-off signal, the power-on state of the main server 11, and the power-on state of the pooling server 13 are all high and low level signals, and the CPLDs can transmit between the two CPLDs through the GPIO ports, and the CPLDs can know the power-on states of the main server 11 and the pooling server 13 and whether the power-on or power-off operation is currently required by detecting the level states of the corresponding GPIO ports. In addition, three independent GPIOs make above-mentioned three kinds of signals can not influence each other, be favorable to the smooth realization of the cooperation power-on and power-off scheme that this application provided, further improved the reliability.
The utility model provides a server is cooperative to power on and power off device, on the basis of current main server CPLD and pooling server CPLD, increased the communication connection between the two, and connect the PWRGD end of each other part power management chip of server with respective CPLD, make CPLD can realize the judgement to current server power on state through monitoring PWRGD end, based on the above-mentioned relation of connection, main server CPLD and pooling server CPLD need not BMC can realize the monitoring and transmission to server power on state, and the transmission of on-off signal, thereby satisfy the communication condition of carrying out server power on and off, and then just rely on two CPLD just can realize the main server with the mode of hardware and power off cooperatively, relative to the scheme that realizes server cooperation power on and off through BMC in the form of software at present, this kind of scheme is not influenced by BMC fortune dimension, and the hardware implementation mode is more stable, has improved the reliability of server cooperation power on and power off scheme greatly, be favorable to protect the server not cause the crash because of power on and power off abnormity, improve the service life of server.
For the device provided by the above embodiment, this embodiment further provides a method for powering on and powering off the server cooperatively, which is applied to the device, and is divided into two sides, namely, the main server CPLD and the pooling server CPLD, and when the device is applied to the main server CPLD side, as shown in fig. 2, the method includes:
s21: and when the starting signal is detected, the starting signal is sent to the CPLD.
The purpose of step S21 is to facilitate the pooling server CPLD to perform a boot operation.
S22: and detecting whether the power-on state of the pooling server returned by the pooling server CPLD is the power-on state, if so, turning to step S23.
S23: and executing the starting operation.
When the pool server CPLD detects that the pool server and the PWRGD terminals of the power management chips of other components of the pool server are in the electrified state, the electrified state of the pool server is set to be in the electrified state;
s24: and when the shutdown signal is detected, performing shutdown operation.
S25: and detecting whether the power-on state of the PWRGD end of the power management chip of the main server and other parts of the main server is a power-off state, if so, turning to the step S26.
S26: and sending a shutdown signal to the CPLD (Complex programmable logic device) of the pooling server, and setting the power-on state of the main server to be a power-off state.
The purpose of step S26 is to cause the pooling server CPLD to perform a shutdown operation.
Further, this example also provides a preferred embodiment, as shown in fig. 2, the method further includes:
step S22 further includes: if not, go to step S27.
S27: and latching the abnormal starting state of the pooling server to a register.
Step S25 further includes: if not, go to step S28.
S28: and latching the shutdown abnormal state of the master server to a register.
In the embodiment, when the power-on failure of the main server or the pooling server causes the failure of the whole server in cooperation with the power-on and power-off process, the abnormal state is latched into the register, so that subsequent operation and maintenance personnel can obtain the abnormal power-on information through the register to remove the fault.
Meanwhile, another possible implementation scheme exists, in which a register is connected with the BMC, so that the BMC can acquire an abnormal state when power-up and power-down fail cooperatively, and take corresponding operations.
Similarly, when the method is applied to the pooled server side, as shown in fig. 3, the method includes:
s31: and when a starting signal sent by the main server CPLD is received, the starting operation is executed.
S32: detecting the power-on state of the PWRGD end of the power management chip of the pooling server and other components of the pooling server, and if the power-on state is detected, setting the power-on state of the pooling server to be the power-on state.
The purpose is to facilitate the main server CPLD to execute the boot operation.
S33: and when a shutdown signal sent by the CPLD is detected, detecting the power-on state of the main server returned by the CPLD.
S34: if the power-off state is the power-off state, the shutdown operation is executed.
When the CPLD detects that the power management chip PWRGD ends of the main server and other components of the main server are in the powered-off state, the power-on state of the main server is set to be in the powered-off state.
In addition, it should be noted that, when the power-on signal and the power-off signal are transmitted between the CPLD of the main server and the CPLD of the pooling server, a preferred embodiment is to transmit the signals in a transparent transmission manner. Transparent transmission, that is, transparent transmission, is a transmission mode which is only responsible for transmitting the transmitted content from a source address to a destination address regardless of the transmitted service content in communication, and does not change the service data content, so as to further improve the reliability of the server cooperating with power on and power off.
The server cooperation power-on and power-off method provided by the application provides a control scheme for the server cooperation power-on and power-off device, when the server is electrified in cooperation, a main server CPLD receives a power-on signal firstly, and sends the power-on signal to a pooling server CPLD; after receiving the starting signal, the CPLD of the pooling server controls the pooling server to be powered on, detects the power-on state, and updates the power-on state after the power-on is successful so as to be monitored by the CPLD of the main server; and after monitoring that the pooling server is electrified, the CPLD of the main server controls the electrification of the main server, so that the whole cooperative electrification process is completed. The server is in coordination with the power-off in the same way, the two CPLDs are in communication connection, the coordination power-off is completed in a hardware mode, and the stability is higher compared with a software implementation mode. Meanwhile, the method does not need the BMC, so that the situation that the cooperative power on and power off cannot be used due to frequent operation maintenance operation of the BMC is avoided, normal operation of the server is guaranteed, and the reliability of the cooperative power on and power off scheme is further improved.
In the above embodiment, the description of the cooperative power-on and power-off scheme is performed from both sides of the CPLD of the main server and the CPLD of the pooling server, so as to more clearly describe the cooperative power-on and power-off method for the server provided by the present application, in this embodiment, the whole process is divided into a power-on process and a power-off process to further describe with reference to an example:
