Description

Server power supply system and server

Technical Field

The invention relates to the technical field of servers, in particular to a server power supply system and a server.

Background

At present, Management and control of power consumption of a server power supply become a current research focus, in the prior art, an operation and maintenance manager generally controls the power consumption of the server power supply through remote Management software, and a premise for implementing this control strategy is a power consumption capping technology based on an intel ME (Management Engine).

Referring to fig. 1, fig. 1 is a schematic diagram of a BMC-ME-PSU communication link in a server system in the prior art. In the process of reading Power consumption information of a PSU (Power supply unit) by a BMC (Baseboard Management Controller), first, an ME in a PCH (Platform control unit) reads Power consumption information of the PSU in a server through an SMBus bus, and then, the BMC reads the Power consumption information of the PSU from the ME through an I2C bus.

When the server enters the S0 state from the S5 state during the process of executing the boot operation, the server motherboard sends a boot trigger signal to the BMC and the PCH simultaneously to trigger a system signal of the BMC monitoring server and trigger the PCH to control the server to boot. However, due to the problem of the power-on timing sequence between the BMC and the PCH, the BMC may probabilistically monitor the ME, and in this case, normal communication between the BMC and the ME cannot be performed, which may not only result in that the BMC cannot obtain power consumption information of the PSU from the ME, but also cause the BMC to generate a "false alarm". Obviously, if the situation occurs, the operation and maintenance manager is required to solve the problem on site, so that the operation and maintenance cost of the operation and maintenance manager to the server is greatly increased. At present, no effective solution exists for the technical problem.

Therefore, the technical problem to be solved by the technical staff in the field is how to solve the problem of the 'false alarm' generated by the BMC due to the power-on time sequence of the BMC and the PCH and reduce the operation and maintenance cost of the operation and maintenance staff for the server.

Disclosure of Invention

In view of this, an object of the present invention is to provide a server power system and a server, so as to solve the problem of BMC false alarm caused by power-on sequence of BMC and PCH, and reduce operation and maintenance cost of an operation and maintenance manager to the server. The specific scheme is as follows:

a server power supply system comprising:

the PSU is used for providing an energy source for the target server;

the programmable logic device is used for receiving a starting trigger signal of the target server and respectively sending the starting trigger signal to the PCH and the BMC;

the PCH provided with the ME is respectively connected with the PSU and the programmable logic device and is used for acquiring power consumption information of the PSU by using the ME when the starting trigger signal is received;

the BMC provided with the delayer is connected with the PCH and is used for delaying the start trigger signal for a preset time by using the delayer and then sending the start trigger signal to the PCH so as to acquire the energy consumption information of the PSU through the ME when the start trigger signal is received.

Preferably, the BMC is connected to the PSU through a relay.

Preferably, the relay is Buffer.

Preferably, the programmable logic device is specifically a CPLD or an FPGA.

Preferably, the method further comprises the following steps:

and the memory is connected with the BMC and is used for storing the log file of the BMC.

Preferably, the memory is a memory.

Preferably, the method further comprises the following steps:

the first Reset module is arranged in a PSU and used for restarting a first I2C port when the first I2C port in the PSU is detected to be failed.

Preferably, the method further comprises the following steps:

and the second Reset module is arranged in the BMC and is used for restarting the second I2C port when detecting that the second I2C port in the BMC fails and/or the PEC transmission between the BMC and the PSU fails.

Correspondingly, the invention also discloses a server, which comprises the server power supply system disclosed as the above.

Therefore, in the invention, when the programmable logic device receives the starting trigger signal of the target server, the starting trigger signal of the target server is sent to the PCH and the BMC; when the PCH receives a starting trigger signal of a target server, acquiring power consumption information of a PSU (power system unit) in the target server through an ME (ME) in the PCH; when the BMC receives the start trigger signal of the target server, the delay device arranged in the BMC is used for delaying the start trigger signal of the target server for a preset time, and then the start trigger signal of the target server is sent to the PCH, so that the energy consumption information of the PSU is obtained through the ME in the PCH. Therefore, the technical defect that the BMC cannot normally monitor the ME due to the power-on time sequence problem between the PCH and the BMC in the prior art is solved by using the clock delay between the BMC and the PCH. Obviously, when the BMC can normally monitor the ME and normally communicate with the PCH, the BMC can acquire the power consumption information of the PSU in the target server from the ME of the PCH and control the power consumption of the target server. Under the condition, the BMC can not generate a false alarm phenomenon, so that the operation and maintenance cost of the operation and maintenance manager to the server can be relatively reduced. Correspondingly, the server disclosed by the invention also has the beneficial effects.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 2, fig. 2 is a structural diagram of a server power supply system according to an embodiment of the present invention, where the server power supply system includes:

a PSU11 for providing a source of energy for a target server;

the programmable logic device 12 is configured to receive a power-on trigger signal of the target server, and send the power-on trigger signal to the PCH13 and the BMC14, respectively;

the PCH13 provided with the ME is respectively connected with the PSU11 and the programmable logic device 12 and is used for acquiring power consumption information of the PSU11 by using the ME when receiving a starting trigger signal;

the BMC14 provided with a delayer is connected to the PCH13, and is configured to, when receiving the power-on trigger signal, delay the power-on trigger signal by a preset time using the delayer and then send the power-on trigger signal to the PCH13, so as to obtain the energy consumption information of the PSU11 through the ME.

In this embodiment, a server power system is provided, by which the problem of "false alarm" generated by the BMC due to the power-on timing sequence of the BMC and the PCH can be avoided, and the operation and maintenance cost of the server by the operation and maintenance manager can be reduced.

In the server power system shown in fig. 2, when the programmable logic device 12 receives the power-on trigger signal of the target server, the power-on trigger signal of the target server is respectively sent to the PCH13 and the BMC14 to trigger the PCH13 and the BMC14 to operate. That is, when the programmable logic device 12 receives the Power-ON trigger signal triggered by the Power Button of the target server, the programmable logic device 12 will pull the PS-ON level low to generate a Power Good signal, so as to establish the P12V level. When the programmable logic device 12 establishes the P12V level and divides the P12V level, the programmable logic device 12 can trigger the BMC14 and the PCH13 to operate.

When the PCH13 receives a power-on trigger signal of a target server sent by the programmable logic device 12, the power consumption information of the PSU11 is obtained through the ME set in the PCH 13. Meanwhile, when the BMC14 receives the boot trigger signal of the target server sent by the programmable logic device 12, the boot trigger signal is delayed for a preset time by using a delay device provided in the BMC14, and then the boot trigger signal of the target server is sent to the PCH13, so as to obtain the energy consumption information of the PSU11 through the ME in the PCH 13.

That is, in this embodiment, the BMC14 uses a delay to process and control the target trigger signal, and when the BMC14 receives the power-on trigger signal sent by the target server, the delay fault-tolerant processing is performed. It can be considered that, after the PCH13 is delayed for the preset time, the PCH13 must normally operate, and in this case, the BMC14 obtains the power consumption information of the PSU11 collected by the ME after the PCH13 is delayed for the preset time, so that the BMC14 and the ME can normally communicate with each other.

That is to say, the specific operation of the BMC14 in performing the delay fault-tolerant processing on the target trigger signal includes: firstly, a time delay device is arranged in the BMC14 and used as a fault-tolerant signal for collecting PCH13 by the BMC 14; then, the BMC14 embeds the received target trigger signal in the delayer, and transmits the delayed target trigger signal to the PCH13, so that the delayed fault-tolerant processing of the boot trigger signal of the target server can be realized, and thus normal communication between the BMC14 and the ME can be performed. It can be thought that when the BMC14 and the ME can perform normal communication, the problem of "false alarm" generated by the BMC due to the power-on sequence of the BMC and the PCH can be avoided, so that the operation and maintenance cost of the operation and maintenance manager on the server can be reduced.

Specifically, in this embodiment, the ME in the PCH13 reads the power consumption information of the PSU11 through the pmbus1.2 bus, the BMC14 reads the power consumption information of the PSU11 from the ME through the I2C bus, and the preset time for the delay of the delay unit in the BMC14 is set to 3 s. Of course, in practical application, the delay time of the delay unit can be adaptively adjusted according to different practical situations.

In addition, it should be noted that the server power supply system provided in this embodiment can also be used in application scenarios such as a computer system, a server, a storage system, a switch, a router, a security monitoring device, and an electric power monitoring device.

Therefore, in the invention, when the programmable logic device receives the starting trigger signal of the target server, the starting trigger signal of the target server is sent to the PCH and the BMC; when the PCH receives a starting trigger signal of a target server, acquiring power consumption information of a PSU (power system unit) in the target server through an ME (ME) in the PCH; when the BMC receives the start trigger signal of the target server, the delay device arranged in the BMC is used for delaying the start trigger signal of the target server for a preset time, and then the start trigger signal of the target server is sent to the PCH, so that the energy consumption information of the PSU is obtained through the ME in the PCH. Therefore, the technical defect that the BMC cannot normally monitor the ME due to the power-on time sequence problem between the PCH and the BMC in the prior art is solved by using the clock delay between the BMC and the PCH. Obviously, when the BMC can normally monitor the ME and normally communicate with the PCH, the BMC can acquire the power consumption information of the PSU in the target server from the ME of the PCH and control the power consumption of the target server. Under the condition, the BMC can not generate a false alarm phenomenon, so that the operation and maintenance cost of the operation and maintenance manager to the server can be relatively reduced.

Based on the above embodiments, the present embodiment further describes and optimizes the technical solution, please refer to fig. 3, and fig. 3 is a schematic connection diagram of the BMC and the PSU according to the embodiment of the present invention. As a preferred embodiment, the BMC14 is connected to the PSU11 via a relay.

Referring to fig. 1, fig. 1 is a schematic diagram of a BMC14-ME-PSU11 communication link in a server system in the prior art. In the BMC-ME-PSU communication link, the BMC14 needs to use the ME to obtain the power consumption data of the PSU11 during the process of obtaining the power consumption data of the PSU 11. In this process, if any ME fails, BMC14 and PSU11 will not communicate properly, and BMC14 will generate a "false alarm".

In this embodiment, to solve the above technical problem, the BMC14 and the PSU11 are directly connected through the relay, because when the BMC14 and the PSU11 are connected through the relay, the BMC14 can directly communicate with the PSU11 in any state, and thus, interference and influence of other foreign signals and/or transit links on the information transmission process of the BMC14 and the PSU11 can be avoided.

In addition, due to the complex electromagnetic interference environment of the data center room, the communication link of the data center room is inevitably affected, so that a small probabilistic signal interference phenomenon occurs in the data center room, and the communication quality of the communication link of the data center room is affected. Since the ME was developed by intel corporation, the ME is particularly critical and critical to the received signal quality, and no corresponding fault tolerance mechanism has been developed in the ME's own communication link, so that the I2C bus between BMC14 and PSU11 is in a deadlock when the communication link between BMC14 and PSU11 is disturbed. That is, the ME suspends the I2C bus between BMC14 and PSU11 and stops transmission of the data signal, and in this case, BMC14 may also generate a "false alarm" because power consumption information of PSU11 is not detected. Obviously, after BMC14 and PSU11 are directly connected through a relay, if communication between BMC14 and PSU11 is interrupted, because a fault-tolerant mechanism is provided in BMC14, in this case, BMC14 will continue to initiate a communication handshake mechanism to PSU11, and ensure that data communication transmission between BMC14 and PSU11 is resumed after PSU11 responds, so that the probability of "false alarm" generated by BMC14 can be further reduced.

As a preferred embodiment, the relay is specifically a Buffer.

Specifically, in the embodiment, a Buffer is set as a relay between the BMC14 and the PSU11, please refer to fig. 4, and fig. 4 is a schematic diagram illustrating that the BMC14 and the PSU11 are connected through the Buffer according to the embodiment of the present invention. It can be understood that, because the Buffer is the most widely used Buffer device in the actual operation process, and the Buffer also has the advantages of easy programming, reliable operation, and the like, when the relay is set as the Buffer, the overall usability of the server power supply system provided by the present application can be further improved. Of course, in practical applications, the number of buffers is also adaptively adjusted according to practical situations, and will not be described in detail herein.

Based on the above embodiments, the present embodiment further describes and optimizes the technical solution, and as a preferred implementation, the programmable logic device 12 is specifically a CPLD or an FPGA.

In this embodiment, the programmable logic device 12 is set as a CPLD (complex programmable gate array), because the CPLD is a programmable logic device with high density and low power consumption, and the CPLD has a faster logic calculation speed, when the programmable logic device 12 is set as a CPLD, the signal transmission speed of the programmable logic device 12 when receiving and forwarding the power-on trigger signal can be relatively increased.

Alternatively, the Programmable logic device 12 may be configured as an FPGA (field Programmable gate array), because the FPGA can achieve greater flexibility in programming compared to other Programmable logic devices, and the FPGA can also achieve a more complex wiring structure and programming logic, so when the Programmable logic device 12 is configured as an FPGA, the overall reliability of the Programmable logic device 12 in the using process can be further improved.

Based on the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the server power supply system further includes:

and the memory is connected with the BMC14 and is used for storing log files of the BMC 14.

In this embodiment, a memory connected to the BMC14 is also provided in the server power system, and the Log file of the BMC14 is stored using the memory. By the aid of the setting mode, safety of the operation information of the server power supply system in the storage process is guaranteed, and when the server power supply system breaks down, workers can find out the reason of the failure of the server power supply system more quickly and accurately through Log information stored in the Log file, so that the failure can be maintained and processed more quickly.

Obviously, the technical scheme provided by the embodiment can improve the user experience when the user uses the server power supply.

In a preferred embodiment, the memory is embodied as a memory.

Specifically, in this embodiment, the storage is set as the memory, and the memory has a faster data access speed than other storage, so that when the storage is set as the memory, a user can write the Log file into the memory more quickly or read the Log file from the memory, thereby further improving user experience when the user uses the server power supply.

Based on the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the server power supply system further includes:

a first Reset module disposed in the PSU11 for restarting the first I2C port when detecting a failure of the first I2C port in the PSU 11.

It can be understood that, since a small probability of signal interference occurs in the data center room and affects the communication quality of the communication link of the data center room, when the communication link between the BMC14 and the PSU11 is interfered, the I2C bus between the BMC14 and the PSU11 is in a deadlock state, that is, the ME suspends the I2C bus between the BMC14 and the PSU11 and stops transmitting the data signal, in this case, the communication link between the BMC14 and the PSU11 cannot be recovered.

Therefore, in this embodiment, in order to prevent interference and influence on normal operation of the server power system due to failure of the first I2C port in the PSU11, a first Reset module is further provided in the PSU11, that is, when it is detected that the first I2C port in the PSU11 fails, the first I2C port in the PSU11 is restarted by using the first Reset module, and in this process, the BMC14 keeps the PMBus I2C between the BMC14 and the PSU11 unchanged, so that the problem that the normal operation of the server power system is affected due to failure of the I2C in the PSU11 during communication between the BMC14 and the PSU11 can be avoided.

Based on the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the server power supply system further includes:

and a second Reset module disposed in the BMC14, configured to restart the second I2C port when detecting that the second I2C port in the BMC14 fails and/or that PEC transmission between the BMC14 and the PSU11 fails.

It is understood that when the second I2C port in the BMC14 fails and/or the PEC (Parity Check Parity) transmission between the BMC14 and the PSU11 fails, the I2C bus between the BMC14 and the PSU11 is deadlock and affects the normal operation of the server power system, so in this embodiment, a second Reset module is also provided in the BMC 14. That is, when a failure of the second I2C port in the BMC14 and/or an error in the PEC transmission between the BMC14 and the PSU11 is detected, the second Reset port in the BMC14 is restarted using the second Reset module provided in the BMC14, and thus normal communication between the BMC14 and the PSU11 is restored.

Obviously, by means of the arrangement mode, the problem that the communication link between the BMC14 and the PSU11 is affected due to the fact that the second I2C port in the BMC14 is in failure can be prevented and solved, and therefore the reliability of the server power supply system in the working process can be further improved.

In addition, in the server power supply system provided by the application, because the automatic recovery of the fault communication link can be realized without manual intervention, and the optimal design of the server power supply system is realized, the operation and maintenance cost of the server can be greatly reduced on the premise of not influencing the service application performance of a client.
