Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
For the array server with ARM chips as the processing modules, the processing modules usually adopt CBL-PWR-ON hardware starting circuits, namely power-ON starting circuits, in order to facilitate the hot plug-in function and the functional requirements of the server. However, this brings a problem that the processing module cannot be normally shut down, and even if the processing module is shut down, the processing module is restarted immediately. And the forced shutdown can cause damage to the hardware of the processing module. How to correctly shut down a processing module in an array server which adopts an ARM architecture chip as the processing module, the application provides a shutdown method of the processing module. The method executed in the present embodiment is applied to the control module and includes steps S110 to S130. In order to clear the shutdown method of the processing module applied to the control module provided in this embodiment, please refer to fig. 1.
Step S110: and responding to the acquired shutdown instruction, and determining a processing module to be shutdown according to the shutdown instruction.
In one embodiment, an array server may be composed of a plurality of blades, with a control module and a plurality of processing modules disposed on one blade. The processing module is a part for realizing data processing in the array server, for example, the processing module can be a CPU of ARM architecture and the like; the control module is used for interacting with the outside and comprehensively realizing the control and management of a plurality of processing modules on the blade, such as shutdown operation mentioned in the application. The shutdown instruction may be input by an external control, or may be automatically generated by the processing module, which is not particularly limited. For example, when the external device needs to overhaul a certain processing module in the blade, a shutdown instruction is generated and sent to the control module to control and realize shutdown of the processing module. Or the control module finds that one processing module in the blade has operation faults and needs to be disconnected, and then the control module automatically generates and responds to a shutdown instruction. It can be seen that, since the control module manages a plurality of processing modules, the shutdown command actually needs to have directionality, that is, a certain processing module in the designated blade performs the shutdown operation. Therefore, when the control module acquires the shutdown instruction, the processing module needing shutdown is determined according to the shutdown instruction, and subsequent control is realized on the processing module.
Step S120: and sending a first signal to the processing module, wherein the first signal is used for controlling the processing module to execute a shutdown process.
In one embodiment, step S120: transmitting a first signal to a processing module, comprising: transmitting a first signal to the processing module for a first time; and/or, canceling interference generated when the first signal is transmitted.
In an embodiment, the first signal is sent to control the processing module to perform shutdown, which naturally affects the operation computing power of the array server, so that shutdown operation needs to be carefully performed, that is, shutdown caused by false triggering needs to be prevented. In this regard, in the process of transmitting the first signal in step S120, it is necessary to prevent the erroneous operation by the operation at the control module. Specific operations may include, but are not limited to, sending a first signal for a duration such that a processing module at the receiving end determines whether a shutdown requirement is actually present according to the length of the duration. The specific length of the first time is not specifically limited, and may be 1s, 3s, 5s, etc., which may be arbitrarily set according to practical situations. In addition, it can be understood that, since the array server includes a plurality of blades, one blade realizes overall control of a plurality of processing modules by one control module, and the control to realize shutdown is directional and purposeful. Therefore, interference is inevitably present in the transmission process of the first signal. For this, the interference generated during the transmission of the first signal by the control module is to be eliminated. An embodiment in which a control module and a processing module are connected by a GPIO interface (General-purpose input/output) is described. Assuming that the control module and the processing module are connected through the GPIO_1, whether the GPIO_1 outputs a first signal is respectively corresponding to the two states of high and low level: if GPIO_1 is high level, the processing module is in normal working state; if GPIO_1 is low, i.e., the first signal is output. Therefore, in the process of outputting the low level, the control module can eliminate interference such as level jitter and the like, so that the first signal can be output to the processing module according to the preset requirement. Based on the method, the first signal can be accurately, correctly and error-free transmitted to the processing module, so that abnormal shutdown of the processing module caused by error triggering is avoided, calculation force of the array server is influenced, and normal operation of the array server is ensured.
Step S130: and when the second signal sent back by the processing module is received, cutting off a power supply circuit of the processing module.
In one embodiment, step S130: when receiving the second signal sent back by the processing module, cutting off a power supply circuit of the processing module, and comprising: and after receiving the second signal sent back by the processing module, cutting off the power supply circuit of the processing module in a second time.
In one embodiment, as described above, the processing modules ON the array server are configured as hardware power-ON circuits for CBL-PWR-ON, i.e. power-ON. After the processing module is powered off according to the first signal, if the power supply to the processing module is still maintained, the processing module is powered on again, so that the failure of the power on is caused. For this, after the processing module is turned off, the power supply circuit of the processing module is turned off in time, so that the processing module is practically turned off. Specific operations require cooperation of processing modules, and operations performed by the processing modules will be described in detail below, and are not expanded herein. In short, the processing module sends a second signal for confirming that the processing module is shut down back to the control module after the shut down is confirmed. For this control module, it needs to grasp the window period at the shutdown moment and cut off the power supply of the processing module. That is, after receiving the second signal, the control module needs to cut off the power supply of the processing module in a second time. The second time specific value may be arbitrarily set, and in a preferred embodiment, the second time may be 50ms in consideration of the time of data processing, information transmission, i.e., the switching-off operation. And after the processing module feeds back the second signal, the power supply circuit corresponding to the processing module is cut off in time, so that the processing module is ensured to be capable of being accurately shut down, shutdown failure caused by repeated starting and damage to hardware are avoided, and normal operation of the array server is maintained.
In one embodiment, the method further comprises: when the power failure of the array server is detected, controlling to start a temporary power supply module, wherein the temporary power supply module is used for supplying power for the array server at a third time; continuously sending a first signal to all the processing modules; when a second signal sent back by the processing module is received, cutting off a power supply circuit of the corresponding processing module; and after the power supply circuits of all the processing modules are cut off, the temporary power supply module is closed.
In one embodiment, the foregoing embodiments are all cases where the specified processing module is powered down under normal operation. However, in actual situations, abnormal shutdown situations may occur, for example, the blade is illegally pulled out of the array server, or the machine room fails, which may cause abnormal shutdown of the processing module in the running process. In this case, the processing module cannot run continuously and must be shut down to protect the hardware. And when the control module detects that the array server is powered down, the temporary power supply module is controlled to be started. The temporary power supply module is arranged in each blade of the array server and can supply power for a third time length for all hardware in the blade. The third time length is determined by the capacitance of the temporary power supply module, the amount of hardware in the blade and the power consumption, and at least the time that all the processing modules can be shut down under the condition that the blade is fully loaded can be ensured, for example, the time length of 1 minute, 3 minutes, 5 minutes and the like can be used, and the method is not particularly limited. When the temporary power supply module is started, unlike the processing logic that the control module controls the corresponding processing module to be powered off according to the power-off instruction, in this embodiment, the control module needs to control the power-off of all the processing modules controlled by the temporary power supply module, that is, send the first signal to all the processing modules. The subsequent steps are similar to step S130, and each time the second signal sent back by one processing module is retracted, the power supply circuit of the processing module is correspondingly cut off. The control module may perform the power-off operation of the plurality of processing modules sequentially or simultaneously, and is not limited thereto. After the control module determines that the power supply circuits of all the processing modules are cut off, the temporary power supply module can be turned off, that is, the whole blade or the whole array server is normally turned off. Therefore, for the method flow provided by the embodiment, after the array server is illegally powered off, all the administered processing modules are controlled to enter the shutdown flow to realize shutdown by the power supply of the temporary power supply module, so that the processing modules are ensured to be correctly shut down, the data damage or the hardware damage is avoided, the normal use of the array server is greatly maintained, and the service life of the array server is prolonged.
Therefore, the control module and the processing module in the array server can be controlled to be matched with each other, the power supply of the processing module is cut off after the processing module is powered off, the problem that the processing module is restarted repeatedly after the processing module is powered off is avoided, the processing module is ensured to be powered off correctly, data damage or loss is avoided, the normal use of the array server is greatly maintained, and the service life of the array server is prolonged.
Fig. 2 is a flowchart of a process module shutdown method applied to a process module according to an embodiment, which specifically includes steps S210 to S230.
Step S210: and acquiring a first signal issued by the control module.
Step S220: and when the duration of the first signal is longer than the first time, executing a shutdown procedure to shutdown the processing module.
Step S230: and after the processing module is shut down, feeding back a second signal to the control module.
In an embodiment, in the process of shutting down the processing module in the array server, not only the control of the control module on the processing module, but also the cooperation control of the processing module is required to realize the whole process. Specifically, a shutdown process is executed according to the received first signal to save the existing operation data, stop the operation process, and shut down the power supply to carry out a sleep state so as to realize shutdown. In addition, to ensure accurate transmission of the first signal, it is also necessary to identify the first signal before performing the shutdown procedure, for example, whether the transmission time lasts for more than the first time, so as to prevent no triggering due to interference. In addition, if the first signal carries the designability information, the first signal can be analyzed to judge whether the shutdown instruction corresponding to the first signal is really designating self shutdown. The management flow is performed only if the first signal does specify that the processing module is powered off. Otherwise, the first signal is ignored and operation is continued. In addition, when the shutdown is completed, due to the characteristic set by the processing module in the array server, a second signal which is confirmed to be shutdown is fed back to the control module, so that the control module is coordinated to disconnect a power supply circuit of the processing module, the shutdown is practically realized, and the shutdown failure caused by restarting is avoided.
In one embodiment, the method further comprises: executing a shutdown process to shut down the processing module in response to the shutdown instruction; and after the processing module is shut down, feeding back a second signal to the control module.
In an embodiment, the foregoing embodiments are all used for explaining the process that the control module responds according to the shutdown instruction, and correspondingly controls shutdown of the corresponding processing module. However, in practice, the processing module may generate a shutdown instruction by itself in some situations during the actual operation, and for this purpose, the control module needs to cooperate to achieve a practical shutdown, so as to avoid restarting. The specific process is that when the processing module obtains the shutdown instruction by itself, the processing module shuts down by itself. And sending a second signal to the control module to request the control module to be matched with the power supply circuit of the disconnection processing module so as to practically realize shutdown and avoid shutdown failure caused by restarting.
Therefore, the control module and the processing module in the array server can be controlled to be matched with each other, the power supply of the processing module is cut off after the processing module is powered off, the problem that the processing module is restarted repeatedly after the processing module is powered off is avoided, the processing module is ensured to be powered off correctly, data damage or loss is avoided, the normal use of the array server is greatly maintained, and the service life of the array server is prolonged.
Fig. 3 is a schematic flow timing diagram of a control module for controlling a processing module to be turned off according to an embodiment, which specifically includes steps S310 to S350.
Step S310: the control module responds to the acquired shutdown instruction, and determines a processing module to be shutdown according to the shutdown instruction.
In one embodiment, an array server may be composed of a plurality of blades, with a control module and a plurality of processing modules disposed on one blade. The processing module is a part for realizing data processing in the array server, for example, the processing module can be a CPU of ARM architecture and the like; the control module is used for interacting with the outside and comprehensively realizing the control and management of a plurality of processing modules on the blade, such as shutdown operation mentioned in the application. The shutdown instruction may be input by an external control, or may be automatically generated by the processing module, which is not particularly limited. For example, when the external device needs to overhaul a certain processing module in the blade, a shutdown instruction is generated and sent to the control module to control and realize shutdown of the processing module. Or the control module finds that one processing module in the blade has operation faults and needs to be disconnected, and then the control module automatically generates and responds to a shutdown instruction. It can be seen that, since the control module manages a plurality of processing modules, the shutdown command actually needs to have directionality, that is, a certain processing module in the designated blade performs the shutdown operation. Therefore, when the control module acquires the shutdown instruction, the processing module needing shutdown is determined according to the shutdown instruction, and subsequent control is realized on the processing module.
Step S320: the control module continuously transmits a first signal to the processing module for a first time, and the first signal is used for controlling the processing module to execute a shutdown process.
In an embodiment, the first signal is sent to control the processing module to perform shutdown, which naturally affects the operation computing power of the array server, so that shutdown operation needs to be carefully performed, that is, shutdown caused by false triggering needs to be prevented. In this regard, in the process of transmitting the first signal in step S320, it is necessary to prevent the erroneous operation by the operation at the control module. Specific operations may include, but are not limited to, sending a first signal for a duration such that a processing module at the receiving end determines whether a shutdown requirement is actually present according to the length of the duration. The specific length of the first time is not specifically limited, and may be 1s, 3s, 5s, etc., which may be arbitrarily set according to practical situations. In addition, it can be understood that, since the array server includes a plurality of blades, one blade realizes overall control of a plurality of processing modules by one control module, and the control to realize shutdown is directional and purposeful. Therefore, interference is inevitably present in the transmission process of the first signal. For this, the interference generated during the transmission of the first signal by the control module is to be eliminated. The first signal can be accurately, correctly and correctly transmitted to the processing module, so that abnormal shutdown of the processing module caused by false triggering is avoided, calculation force of the array server is influenced, and normal operation of the array server is ensured.
Step S330: and when the processing module continuously acquires the first signal for the first time, executing a shutdown process to shutdown the processing module.
In an embodiment, in the process of shutting down the processing module in the array server, not only the control of the control module on the processing module, but also the cooperation control of the processing module is required to realize the whole process. Specifically, a shutdown process is executed according to the received first signal to save the existing operation data, stop the operation process, and shut down the power supply to carry out a sleep state so as to realize shutdown. In addition, to ensure accurate transmission of the first signal, it is also necessary to identify the first signal before performing the shutdown procedure, for example, whether the transmission time lasts for more than the first time, so as to prevent no triggering due to interference. In addition, if the first signal carries the designability information, the first signal can be analyzed to judge whether the shutdown instruction corresponding to the first signal is really designating self shutdown. The management flow is performed only if the first signal does specify that the processing module is powered off. Otherwise, the first signal is ignored and operation is continued.
Step S340: after the processing module is shut down, the processing module feeds back a second signal to the control module.
Step S350: and when the control module receives the second signal sent back by the processing module, cutting off a power supply circuit of the processing module.
In an embodiment, when the shutdown is completed, due to the characteristic set by the processing module in the array server, a second signal that has confirmed the shutdown needs to be fed back to the control module, so as to coordinate the control module to disconnect the power supply circuit of the processing module, thereby actually realizing the shutdown and avoiding the shutdown failure caused by restarting. In short, the processing module sends a second signal for confirming that the processing module is shut down back to the control module after the shut down is confirmed. For this control module, it needs to grasp the window period at the shutdown moment and cut off the power supply of the processing module. That is, after receiving the second signal, the control module needs to cut off the power supply of the processing module in a second time. The second time specific value may be arbitrarily set, and in a preferred embodiment, the second time may be 50ms in consideration of the time of data processing, information transmission, i.e., the switching-off operation. And after the processing module feeds back the second signal, the power supply circuit corresponding to the processing module is cut off in time, so that the processing module is ensured to be capable of being accurately shut down, shutdown failure caused by repeated starting and damage to hardware are avoided, and normal operation of the array server is maintained.
Therefore, the control module and the processing module in the array server can be controlled to be matched with each other, the power supply of the processing module is cut off after the processing module is powered off, the problem that the processing module is restarted repeatedly after the processing module is powered off is avoided, the processing module is ensured to be powered off correctly, data damage or loss is avoided, the normal use of the array server is greatly maintained, and the service life of the array server is prolonged.
Fig. 4 is a schematic flow timing diagram of a self-controlled shutdown of a processing module according to an embodiment, which specifically includes steps S410 to S430.
Step S410: the processing module executes a shutdown process to shutdown the processing module in response to the shutdown instruction
In an embodiment, the foregoing embodiments are all used for explaining the process that the control module responds according to the shutdown instruction, and correspondingly controls shutdown of the corresponding processing module. However, in practice, the processing module may generate a shutdown instruction by itself in some situations during the actual operation, and for this purpose, the control module needs to cooperate to achieve a practical shutdown, so as to avoid restarting. The specific process is that when the processing module obtains the shutdown instruction by itself, the processing module shuts down by itself. The processing module may automatically acquire the shutdown instruction, for example, may include automatically generating the shutdown instruction when the processing module is started or operated, and automatically overhauls that the system level fault exists and cannot be repaired, stopping operation, and waiting for overhauling.
Step S420: after the processing module is shut down, the processing module feeds back a second signal to the control module
Step S430: and when the control module receives the second signal sent back by the processing module, cutting off a power supply circuit of the processing module.
In an embodiment, when the shutdown is completed, due to the characteristic set by the processing module in the array server, a second signal that has confirmed the shutdown needs to be fed back to the control module, so as to coordinate the control module to disconnect the power supply circuit of the processing module, thereby actually realizing the shutdown and avoiding the shutdown failure caused by restarting. In short, the processing module sends a second signal for confirming that the processing module is shut down back to the control module after the shut down is confirmed. For this control module, it needs to grasp the window period at the shutdown moment and cut off the power supply of the processing module. That is, after receiving the second signal, the control module needs to cut off the power supply of the processing module in a second time. The second time specific value may be arbitrarily set, and in a preferred embodiment, the second time may be 50ms in consideration of the time of data processing, information transmission, i.e., the switching-off operation.
Therefore, the processing module can respond according to the shutdown instruction by itself in the operation process to finish the shutdown process, and the second signal is sent back to request the control module to be matched with the power supply circuit corresponding to the processing module to be cut off in time, so that the processing module is ensured to be shut down accurately, shutdown failure caused by repeated starting is avoided, damage to hardware is avoided, and normal operation of the array server is maintained.
