The power supply device of the server needs to provide stable output electric energy, and the running power consumption of the server is met. And there is certain risk only through external power supply for the server, for example power supply breaks down or short circuit etc. leads to the unable normal work of server.
In order to ensure stable operation of the server, multiple power supply modes are generally adopted for simultaneous use, and when a fault occurs, switching is performed to ensure stable power supply of the server. Although the risk of single power supply is solved, the power supply requirement of the server cannot be met because the server has load change in the running process, namely power consumption fluctuation, and the mode of switching redundant power supply cannot effectively and dynamically track the power consumption fluctuation. Meanwhile, in the prior art, a power supply device of the server can work at a non-optimal efficiency point for a long time, so that electric energy resources are wasted.

Namely, the operation is automatically switched, for example, when the bus power supply is in failure, or abnormal, or is powered off, the automatic switching process is executed, and the power module supplies power to ensure the stable operation of the server.
The system can dynamically adjust the number of working states of the main power supply module and the standby power supply module, and the power supply module is kept to work at the optimal efficiency point.

The method can control the power supply mode of the server through the BMC module, and each server can independently run without being influenced by the abnormal bus power supply during power supply. When the server works in different load states during centralized networking power supply, the power supply state of the power supply module is adjusted, so that the server can achieve the optimal working efficiency in real time, and meanwhile, when the server is lightly loaded or in standby, more power supply modules can stop working or work in standby, the service life of the power supply module is prolonged, and the service life of the server is prolonged due to the improvement of the power supply redundancy.

The mainboard 3 of the server 2 is provided with a bus power supply end; the bus power supply end of the server is connected to a bus power supply through a bus power supply line; each server is connected with a power supply module used for supplying power to the server;
the power consumption monitoring module is used for monitoring the power supply state of the server in real time, acquiring the running power consumption of the server in the system after the bus power supply is disconnected, and controlling the running of a preset number of power modules according to the running power consumption to meet the running power consumption of the current server.
The system of the invention has two power supply modes, one mode is to supply power to the server through a bus power supply, and the other mode is to supply power to the server through a power supply module.
For the power module, the power module includes: a main power supply module 6 and a standby power supply module 7; the main power supply module 6 and the standby power supply module 7 are respectively connected with the server to realize a redundant power supply mode for the server; the power consumption monitoring module is also used for acquiring the total operation power consumption of the server in the system in real time, and when the output power of the main power supply module 6 meets the operation power consumption of the server, the standby power supply module 7 is set to be in a standby state.
The power supply system can be applied to the occasions where a plurality of servers are deployed, a main power supply module 6 and a standby power supply module 7 in the power supply module adopt a redundant power supply setting mode, the main power supply module 6 is in a main output state in actual work, and the standby power supply module 7 is in a standby state. If the power output by the main power module 6 cannot meet the running power consumption of the server, the standby power module 7 is started to supply power, and the stable running of the server is ensured.
The power supply module can supply power not only to the connected server but also to other servers in the system through a bus power supply line.
As an embodiment of the present invention, a motherboard of a server may be configured with a 12V bus end as a bus power supply end, and as a 12V connector, bus power supply ends led out by multiple servers are interconnected by bus power supply lines, and the bus power supply lines may adopt copper bars or copper wires to form a 12V power supply bus. The bus power supply realizes interconnection of a plurality of servers through a bus power supply line, namely a 12V power supply bus, and the bus power supply can provide a 12V power supply.
The mainboard of the server is provided with a BMC (baseboard management controller) module 5 and an MOS (metal oxide semiconductor) tube 4; the bus power supply end of the server is respectively connected with a bus power supply and a power supply module through an MOS (metal oxide semiconductor) tube 4; the BMC module 5 is connected with the control end of the MOS tube 4 and controls the on-off of the MOS tube 4; when the BMC module 5 controls the MOS tube 4 to be in a conducting state, the bus power supply supplies power to the server through a bus power supply line and a bus power supply end; when the BMC module 5 controls the MOS tube 4 to be in a cut-off state, the power supply module supplies power to the server.
That is to say, the on/off of the MOS transistor 4 is controlled by the BMC module 5. When the MOS tube 4 is conducted, the bus power supply supplies power to the server in a centralized mode, and the system enters a centralized power supply mode.
According to the running state of the system and the fault or abnormity of the bus power supply, the MOS tube 4 can be controlled to be cut off, at the moment, the power supply mode of the server is switched, and the power supply module PSU supplies power to the server.
The power supply module PSU is a power supply mode that the server is independent of a power supply bus of the whole cabinet 1, and the power supply module PSU of the server independently supplies power. The BMC module 5 is connected with the power supply module PSU through a PMBUS bus.
The power consumption monitoring module can control the working state of the power supply module PSU. The power supply of the server in the system is a redundant power supply mode of the main power supply and the standby power supply. If the power output by the main power module 6 cannot meet the running power consumption of the server, the standby power module 7 is started to supply power, and the stable running of the server is ensured. If the power output by the main power module 6 meets the running power consumption of the server, the standby power module 7 can be set to be in a standby state and does not output power.
In the invention, operation and maintenance personnel can send a control instruction to the BMC module 5 to control the on-off of the MOS tube 4, thereby controlling the power supply mode of the node, namely, the power supply mode is supplied by a power module or a bus power supply. Namely, the operation is automatically switched, for example, when the bus power supply is in failure, or abnormal, or is powered off, the automatic switching process is executed, and the power module supplies power to ensure the stable operation of the server.
In the invention, the voltage of the bus power supply can be monitored in real time by the BMC module 5 of the server or a monitoring module of the system, when the 12V bus fails, the BMC module 5 closes the MOS tube 4, the PSU of the power supply module is automatically converted into a working state from a standby state, and each server is switched into an independent power supply mode.
In the invention, the main power module 6 can adopt commercial power to supply power to the server, or adopt a storage battery to supply power to the server; the standby power supply module 7 adopts a generator as a standby power supply mode.
As an embodiment of the system of the present invention, the power consumption monitoring module obtains the total operating power consumption of the server in the system in real time, and when the output power of the main power module 6 meets the operating power consumption of the server, the standby power module 7 is set to a standby state; namely, the main power supply module 6 is used as the main power supply output, and the standby power supply module 7 is in a standby state.
Due to the increase of the data processing amount of the server or the increase of the power consumption of the server, more power needs to be provided to ensure the stable operation of the server.
At this time, the power consumption monitoring module may monitor the operation state of each server in the system in real time, and certainly, the operation states of the servers in the system are not uniform, some servers have large power consumption, some servers have small power consumption, and the operation states are determined based on different use environments and use states. When the total operation power consumption of a server in the system is increased, the power consumption monitoring module controls the current main power supply module 6 to increase the output power and judges whether the operation power consumption of the server is met; if the output power of the main power supply module 6 reaches the preset output power and is still not satisfied, starting the standby power supply module 7 to output power so as to satisfy the running power consumption of the server;
that is, when the main power module 6 cannot meet the power consumption of the server, the standby power module 7 is executed, and the main power module 7 works simultaneously to meet the use requirement of the server.
In the invention, when the total operation power consumption of the server in the system is less than or equal to the preset output power of the main power module 6, the output power of the standby power module 7 is stopped, and the standby power module 7 is set to be in a standby state. The switching process does not affect the normal operation of the system.
The power consumption monitoring module of the present invention may be implemented using at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a processor, a controller, a microcontroller, a microprocessor, and an electronic unit designed to perform the functions described herein, and in some cases, such an implementation may be implemented in the controller. For a software implementation, the implementation such as a process or a function may be implemented with a separate software module that allows performing at least one function or operation. The software codes may be implemented by software applications (or programs) written in any suitable programming language, which may be stored in memory and executed by the controller.
As an embodiment of the system, when the servers work, the power consumption is different, some servers have high power consumption, some servers have low power consumption, when the system runs, the power consumption monitoring module acquires the running power consumption of each server in the system in real time, controls the main power module 6 corresponding to the server with the maximum current running power consumption to work according to the preset output power, and controls the standby power module 7 to run when the running power consumption of the server is larger than the preset output power of the main power module 6, so that the running power consumption of the server is met;
namely, the main power module 6 corresponding to the server with the maximum operation power consumption is mainly provided for the corresponding server to operate, so that the power consumption of the server is met. And when the running power consumption of the server is less than or equal to the preset output power of the main power supply module 6, stopping the output power of the standby power supply module 7, and setting the standby power supply module 7 to be in a standby state.
As the embodiment of the invention, because the servers are interconnected, if the power output by the power supply module of one server cannot meet the power consumption of the server, the power output by the power supply modules of other servers can be used for making up, so that the power output by the power supply modules of other servers can be used by the servers in the whole system. The power consumption monitoring module can execute the allocation of the output power of the power supply module, the power consumption monitoring module obtains the operation power consumption of each server in the system in real time, the power consumption of the servers can be sorted from large to small, the server with the largest power consumption is found, and the main power supply module 6 corresponding to the server with the largest operation power consumption is mainly provided for the corresponding server to operate, so that the power consumption of the server is met. And then finding out the server with the minimum power consumption, and performing power supplement on the server with the maximum power consumption by using the main power module 6 corresponding to the server with the minimum power consumption.
As the system implementation manner of the present invention, if the power consumption of the server is low in the standby state, all the main power modules 6 are not needed to operate at this time, which does not waste system resources and also affects the service life of the power modules. Specifically, when a server in the system is in a standby state, the power consumption monitoring module acquires standby operation power consumption of the server in the system when the server is in the standby state;
and controlling the preset number of main power supply modules 6 to operate according to the standby operation power consumption, so that the power output by the preset number of main power supply modules 6 is equal to the standby operation power consumption.
That is, the power consumption monitoring module calculates the power consumption of the server in the system when the server is in the standby state, and based on the current power consumption, it is obtained how many main power modules 6 are required to output to meet the current power consumption, and then the main power modules 6 of the corresponding number are controlled to work, so as to ensure the stable operation of the system server. The main power module 6 working when the server is in the standby state can output and supply power to all standby servers of the system, so as to meet the standby requirement.
The server in the system adopts a redundant power supply mode, so that the power consumption of the server is ensured, and the service life of a system power supply module is prolonged. The system consists of a plurality of rack-mounted servers, the power supply of each server is controlled by a BMC (baseboard management controller) module 5 and an MOS (metal oxide semiconductor) tube 4 to be switched, and the servers are led out through a foolproof wiring terminal and then connected in parallel to form a 12V power supply bus.
The BMC module 5 of the server can control the on-off of the MOS tube 4 through an instruction so as to control each node to independently supply power or to realize networking centralized power supply, when the nodes realize networking centralized power supply, each PSU forms a virtual centralized power supply unit, and the system can intelligently control the main power supply module 6 and the standby power supply module 7 to enter a working or standby mode according to the power consumption condition of each server so as to enable the main power supply module 6 and the standby power supply module 7 to achieve the maximum efficiency. The system adopts two paths of power supply, one path of commercial power or storage battery is used as main power supply, and the other path of generator power supply is used as standby power supply, thereby providing a plurality of power supply schemes and meeting the use in different power supply environments.
The system controls the power supply mode of the power module in a PMBUS communication bus mode, and is wide in application range and stable in communication state.
The system can dynamically adjust the number of working states of the main power supply module 6 and the standby power supply module 7, and the power supply modules can be kept working at the optimal efficiency point. The system effectively solves the problem that the operation of a system server is not influenced when the power supply of the centralized bus is disconnected or fails. The BMC module 5 can monitor abnormal disconnection of the bus power supply in real time, close the MOS tube 4 in real time, isolate a 12V bus of the bus power supply, automatically wake up the power supply module by the system, and enable the server to enter an independent power supply mode.
Based on the system, the invention also provides a server power interconnection redundant power supply method, as shown in fig. 2, the method comprises the following steps:
s101, supplying power to a server in a system by a bus power supply through a bus power supply line;
s102, when the power supply of the bus is disconnected, or the power supply of the bus fails, or a power supply switching control signal is received, the power supply module is switched to supply power;
s103, the power consumption monitoring module obtains the operation power consumption of the servers in the system, and controls a preset number of power modules to operate according to the operation power consumption, so that the operation power consumption of the current server is met.
For the method provided by the invention, the switching mode between the bus power supply and the power supply module can be as follows: the BMC module receives a conduction control instruction and controls the conduction of the MOS tube, and a bus power supply end of the server is connected to a bus power supply through a bus power supply line; the bus power supply supplies power to the server;
the BMC module receives the cut-off control instruction and controls the MOS tube to be cut off, so that the bus power supply stops supplying power to the server, and the power module supplies power to the server.
That is, the on/off of the MOS transistor is controlled by the BMC module. When the MOS tube is conducted, the bus power supply supplies power to the server in a centralized mode, and the system enters a centralized power supply mode. According to the system running state and the fault or abnormity of the bus power supply, the MOS tube can be controlled to be cut off, at the moment, the power supply mode of the server is switched, and the power supply module PSU supplies power to the server.
As an embodiment of the method, after the power supply module is switched to supply power, the power consumption monitoring module acquires the total operating power consumption of the server in the system in real time, and when the output power of the main power supply module meets the operating power consumption of the server, the standby power supply module is set to be in a standby state;
it can be understood that when the main power module consumes power of the server, the standby power module is in a standby state, that is, the standby power module is not required to work. The power consumption monitoring module can be used for allocating the power output by the main power supply module, and if the power output by one main power supply module not only meets the requirement of the connected server, the power can be supplied to other servers.
As an embodiment of the present invention, when the total operating power consumption of a server in a system increases, a power consumption monitoring module controls a current main power module to increase output power, and determines whether the operating power consumption of the server is satisfied;
if the output power of the main power supply module is not met after reaching the preset output power, starting the output power of the standby power supply module to meet the running power consumption of the server;
the main power module reaches a preset output power which is in a full-load output state or a 50% output state.
And when the total operation power consumption of the server in the system is less than or equal to the preset output power of the main power supply module, stopping the output power of the standby power supply module, and setting the standby power supply module to be in a standby state.
In the invention, the server system is required to meet the power supply redundancy while running efficiently, the working state and the standby state are switched, the standby power supply module is required to run normally for a long time in the system, and the generator is used as the most standby power supply, so that higher requirements are provided for the long-term running of standby power. As shown in the following table, the following,
Figure BDA0003237510330000111
it can be seen from the above table that the server adopts a 1+1 redundant structure to supply power, the efficiency of the power module is platinum, and the maximum efficiency of the power module reaches 94% when the power module is in a 50% load state. The server is powered by the main power supply module PSU and the standby power supply module PSU, the power supply modules PSU are guaranteed to work at a 50% efficiency point as much as possible, when the access amount of the server is small and the server runs in a light load state, the system closes one power supply module PSU, the efficiency of the other power supply module PSU is improved, and therefore efficient power supply operation of the system is guaranteed. That is, the power module operates at 50% and 100% with higher efficiency.
The method comprises the steps that a power consumption monitoring module acquires the running power consumption of each server in a system in real time, controls a main power supply module corresponding to a server with the largest current running power consumption to work according to preset output power, and controls a standby power supply module to run when the running power consumption of the server is larger than the preset output power of the main power supply module so as to meet the running power consumption of the server;
and when the running power consumption of the server is less than or equal to the preset output power of the main power supply module, stopping the output power of the standby power supply module, and setting the standby power supply module to be in a standby state.
If the main power supply module and the standby power supply module can not meet the power consumption of the server, other power supply modules can be allocated for supplementing. The output power of the power supply module can be dynamically adjusted, and the power consumption of each server can be used.
In the invention, when a server in a system is in a standby state, a power consumption monitoring module acquires the standby operation power consumption of the server in the system when the server is in the standby state;
and controlling the operation of the main power modules in the preset number according to the standby operation power consumption, so that the power output by the main power modules in the preset number is equal to the standby operation power consumption.
The system is internally interconnected through the 12V power supply buses output by all the server power supply modules PSU, and controls the switches of the power supply modules PSU in different load states, so that the system can achieve the optimal output efficiency of the power supply modules PSU at different load points. The high-efficiency operation of the system can be met by adjusting the switch of the main power supply module, so that the standby power supply module can supply power and maintain the output of lower power, and the service life and the maintenance of the generator are facilitated.
For example, in the method for interconnecting and redundantly supplying power to the power supplies of the servers, 5 servers are arranged in a whole cabinet, the maximum power consumption of each server is 2000W, and the power supply modules are configured with main and standby power supply modules which are 1000W PSUs.
When 5 servers are in a standby state or an idle state, the power consumption of the whole cabinet is only about 500W, the power consumption monitoring module can control the 5 servers to only start one main power supply module PSU to be in a power supply state, and the rest 9 power supply modules are in a standby or off state, so that the power supply modules are close to the power consumption point with the maximum efficiency.
When the service of the server is increased and the power consumption is increased, the power consumption monitoring module controls and activates more power supply modules to be in a power supply state, and when the service of the server is reduced and the power consumption is reduced, the power consumption monitoring module controls part of the power supply modules to be in a standby state or a disconnected state.
When the power supply module is switched to the power supply state, the main power supply module of the server with high service power consumption is preferably switched to the power supply state, and when the standby power supply module is switched to the standby or off state, the standby power supply module of the server with low service power consumption is preferably switched to the standby or off state. Because two power supply modules of the server adopt two paths for power supply, the main power supply module is preferentially started to enter a power supply state in system regulation, and the standby power supply module is preferentially set to enter a standby or off state, so that the power supply priority of the main power supply module is ensured, and the service life of the standby power supply module is maintained. Meanwhile, the power module is always kept close to the optimal efficiency point of 50% load, and the power supply efficiency of the server is improved. Under the power supply mode, the whole cabinet system can have fewer power modules to supply power, and more systems are in a standby or off state or a power-down maintenance state.
For example, the power consumption of the whole power supply is 3000W, 3 power supply modules can be in a power supply state, 3 power supply modules are in a standby state, and 4 power supply modules can be in a complete power-down maintenance state, so that the power supply redundancy of the system is greatly improved. The generator of the standby power supply module can be ensured to be in lower power operation in most operation states of the system, the service life of the standby power supply module is prolonged, and waste gas pollution in the operation process of the generator is reduced.
The method can control the power supply mode of the server through the BMC module, and each server can independently run without being influenced by the abnormal bus power supply during power supply. When the server works in different load states during centralized networking power supply, the power supply state of the power supply module is adjusted, so that the server can achieve the optimal working efficiency in real time, and meanwhile, when the server is lightly loaded or in standby, more power supply modules can stop working or work in standby, the service life of the power supply module is prolonged, and the service life of the server is prolonged due to the improvement of the power supply redundancy.
In the method, when the bus power supply is abnormal such as short circuit, the BMC module can control the MOS tube to close and cut off the bus power supply mode in real time, and then the power supply module automatically wakes up to enter a power supply mode for the server. In the method, the centralized power supply mode of the power supply module ensures that the power supply module is in the best working efficiency in real time, so that the system can reach N + N + N redundancy, and the system has multi-path backup power supply complementary use. The system can automatically switch between the bus power supply and the power supply module, and meets the application requirements of the server in the use environments.
