Detailed ways

In order to facilitate understanding of the technical solutions proposed in the embodiments of this application, the technical solutions for improving server utilization are briefly introduced below:

In order to eliminate server vacancies caused by the significant increase in equipment power, the data center uses the equipment's energy consumption training model to conduct power statistics and predictions on the power consumption units of the equipment, and corrects the power cap value of the equipment based on actual business needs. The power cap value is the maximum power of the device under normal circumstances. According to the power cap value of the equipment in the server and the rated power of the server, the deployment of equipment in the server can be further increased and the utilization rate of the server can be improved. Please refer to Figure 1. Figure 1 is a schematic diagram of an effect of improving server utilization provided by an embodiment of the present application. It can be seen from Figure 1 that the rated power of equipment U1, U2,..., U10 is 1000w. When equipment U1 to U10 is installed, the server is fully loaded. After separate processing using the energy consumption training model, the power cap value of each device can be known. For example, the maximum power consumption of U1 in actual applications is 400w, the maximum power consumption of U2 in actual applications is 800w, and the maximum power consumption of U3 in actual applications. The maximum power consumption of U4 is 1200w in practical applications. The maximum power consumption of U10 in practical applications is 1100w. Based on the maximum power of each device in actual applications, the total power is calculated and the total power budget of devices U1 to U10 is 7500w. It can be seen that the server still has a margin of 2500w that can be provided to additional devices. Depending on the actual usage, 2 to 3 devices with a rated power of 1000w can be added to the server to achieve the purpose of improving server utilization.

Based on the above solution, although the utilization rate of the server has been improved, it still cannot exceed the total power of the server and the service The total power of the server is still an insurmountable gap that limits the improvement of the computing power of the data center. How to further improve the computing power of the data center based on the existing circuits and servers has become an urgent problem to be solved.

The embodiments of the present application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Persons of ordinary skill in the art will know that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

The terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments described herein can be practiced in sequences other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus that encompasses a series of steps or units and need not be limited to those explicitly listed. Those steps or elements may instead include other steps or elements not expressly listed or inherent to the process, method, product or apparatus.

The server provided by the embodiment of this application is applied to the server of the data center. The server can accommodate standard or non-standard power-consuming units such as switches, computing devices, and network storage, and provide power to these power-consuming units. For ease of understanding, the more common server structures are first introduced in conjunction with Figure 2. Figure 2 is a schematic structural diagram of a server provided by an embodiment of the present application. Currently, the more common servers usually include: power distribution unit a (power distribution unit, PDU) 203 and PDUb 204.

Among them, PDUa203 is electrically connected to the first power supply 201 and the power unit 205, and is used to provide 220v AC power to the power unit 205 with a certain power;

PDUb 204 is electrically connected to the second power supply 202 and the power consumption unit 205, and is used to provide 220v AC power to the power consumption unit 205 with a certain power.

In view of the above structure, this application proposes to replace the PDUa used to provide 220v AC power to the power unit 205 with a PDU that can provide DC power to the power unit 205. By converting the 220v AC power provided by the power supply into DC power, the PDUa can be used when the power supply is insufficient. At this time, the battery unit supplies power to the power-consuming unit 205, thereby improving the maximum total power that the server can provide to the power-consuming unit 205 based on the existing server and computer room.

Embodiments of the present application provide a server that is used to increase the total power of the server based on the existing computer room circuits, thereby increasing the computing power of the data center. This application also provides a power supply method, computer-readable storage media, computer program products, etc. Each is explained in detail below.

The server provided by the embodiment of the present application will be introduced below with reference to Figure 3. Figure 3 is another structural schematic diagram of the server provided by the embodiment of the present application. The server includes: a first DC-AC power conversion unit 301, a first PDU 303, a first battery unit 305 and a management unit 307.

Among them, the first AC-DC conversion unit 301 is electrically connected to the first power supply 201, the first PDU 303 and the first battery unit 305, and converts the 220v AC voltage provided by the first power supply 201 into a DC voltage, and uses the DC voltage as The first PDU 303 provides electrical energy of the first power.

Optionally, the DC voltage can be 240V DC voltage. In practical applications, the DC voltage can fluctuate between 180v-300v.

The first PDU 303 is electrically connected to the power consuming unit 205, and provides the power consuming unit 205 with electrical energy of the first power using the DC voltage. The power consumption unit 205 includes equipment such as servers or switches.

When the rated power of the power-consuming unit is less than or equal to the first threshold, the first PDU 303 provides the second function to the power-consuming unit. All the electric energy of the rate is provided by the first AC to DC power conversion unit 301. For ease of explanation, the rated power of the power-consuming unit may also be called the second power. When the power-consuming unit includes multiple devices, the second power is the sum of the rated powers of all devices.

When the second power is greater than the first threshold, the electric energy of the second power provided by the first PDU 303 to the power-consuming unit may be provided by the first AC-DC power conversion unit 301 and the first battery unit 305 . Among them, the first AC to DC power conversion unit 301 provides electric energy with a first power, and the first battery unit 305 provides electric energy with a third power. The third power is the difference between the second power and the first power.

Specifically, the first AC-DC power conversion unit 301 includes an adjustment module 3011, which makes the output voltage of the first AC-DC power conversion unit smaller than the output voltage of the first battery unit.

The first AC-DC power conversion unit 301 is connected in parallel with the first battery unit 305. When the second power is greater than the first threshold, the adjustment module 3011 adjusts the output voltage of the first AC-DC power conversion unit 301 so that the The output voltage is less than the output voltage of the first battery unit 305, so that the first battery unit 305 provides the first PDU 303 with electrical energy of the third power, and the first DC-AC conversion unit 301 provides the first PDU 303 with electrical energy of the first power, wherein the third power One power is equal to the rated power of the first AC to DC power conversion unit 301 . The first battery unit 305 can provide the power consumption unit 205 with electrical energy of the third power to meet the power demand of the power consumption unit 205 .

For example, the output voltage of the first AC-DC conversion unit 301 is 240v, and the output voltage of the first battery unit 305 is 230v. When the second power is greater than the first threshold, the power that the first AC-DC conversion unit 301 can provide has been Unable to meet the power demand of the power consumption unit 205, the adjustment module 3011 adjusts the output voltage of the first AC to DC power conversion unit 301 to below 230v, so that the first battery unit 305 starts to output electric energy. When the first battery unit 305 starts to pass the first After the PDU 303 supplies power to the power consumption unit 205, the output voltage of the first AC-DC power conversion unit 301 and the output voltage of the first battery unit 305 are dynamically adjusted to 228v, so that the first AC-DC power conversion unit 301 and the first battery unit 305 pass through the first power supply unit 305 respectively. A PDU 303 provides the electric energy of the first power and the third power to the power unit 205 .

It should be noted that when the second power is greater than the first threshold, the operation method when the first battery unit 305 is required to power the first PDU 305 is only an example, and can be adjusted in combination with actual application scenarios in actual applications. There are no restrictions here.

Optionally, the first AC-DC power conversion unit 301 is also used to charge the first battery unit 305 when the first power is less than the rated power of the first AC-DC power conversion unit 301 .

When the first power is less than the rated power of the first AC-DC power conversion unit 301, the first AC-DC power conversion unit 301 can increase the output voltage of the first AC-DC power conversion unit 301 to above the rated voltage of the first battery unit 305, to achieve: The first battery unit 305 is charged.

For example, the output voltage of the first AC-DC conversion unit 301 is 240v, and the rated voltage of the first battery unit 305 is 230v. As the power consumption of the power unit 205 as a load continues to increase, the first AC-DC conversion unit 301 The output voltage will also continue to decrease. When the output voltage of the first AC-DC conversion unit 301 is greater than 230v, the first AC-DC conversion unit 301 can charge the first battery unit 305.

Because the battery's power supply capacity will continue to change with its remaining power. When the second power is greater than the first threshold, in order to ensure that the electric energy of the second power provided by the first battery unit 305 and the first AC-DC conversion unit 301 for the first PDU 303 can satisfy the use of the power consumption unit 205, the management unit 307 manages The unit 307 is electrically connected to the first AC to DC power conversion unit 301, the first PDU 303 and the power consumption unit 205, and is used to obtain the second power, and when the second power is greater than or equal to the first threshold, provide power to the first DC to AC power conversion unit. 301 sends the first signal to make the first DC-AC power conversion unit After receiving the first signal, the unit 301 reduces the output voltage of the first DC-to-AC power conversion unit 301 to below the rated voltage of the first battery unit 305 . When the second power is less than the first threshold, a second signal is sent to the first DC-AC power conversion unit 301, so that after receiving the second signal, the first DC-AC point conversion unit 301 converts the first DC-AC power conversion unit The output voltage of 301 is increased above the rated power of first battery unit 305 .

Optionally, the management unit 307 is electrically connected to the first battery unit 305 and is used to obtain the remaining power of the first battery unit 305 and determine the upper power limit of the first battery unit 305 based on the remaining power of the first battery unit 305 . And dynamically adjust the power consumed by the power consumption unit 205. The first threshold is the rated power of the first AC-to-DC conversion unit 301 .

When the third power is greater than the power upper limit of the first battery unit, the management unit adjusts the power unit to reduce the power consumption of the power unit, thereby reducing the third power to ensure normal operation of the power unit.

Specifically, after obtaining the remaining power of the first battery unit 305, the management unit 307 obtains the upper power limit of the first battery unit 305 based on the preset relationship between the remaining power and the upper power limit of the first battery unit 305. When the When the sum of the upper power limit of a battery unit 305 and the rated power of the first AC-DC conversion unit 301 is less than the second power, the management unit 307 sends a load limit signal to the power unit 205 at regular intervals, and the power unit 205 actively adjusts the load. The power demand is until the second power is less than or equal to the sum of the power upper limit of the first battery unit 305 and the rated power of the first AC-to-DC conversion unit 301 . Or, send a load limit signal to the first PDU 303. After receiving the load limit signal, the first PDU performs partial power-off processing on the socket of the first PDU 303 until the second power is less than the upper power limit of the first battery unit 305 and the second power limit. The sum of the rated power of the AC/DC conversion unit 301.

In the embodiment of the present application, the management unit dynamically detects the remaining power of the first battery unit, and determines the upper power limit of the first battery unit based on the remaining power of the first battery unit. When the third power is greater than the upper power limit of the first battery unit, Adjust the power-consuming unit to reduce the load on the power-consuming unit and reduce the second power to ensure the normal operation of the power-consuming unit. For example, the management unit can send a load limit signal to the first PDU to instruct the first PDU to power off the connected device. Through the dynamic scheduling of the management unit, the server is prevented from being powered off due to overload, and the server's performance is improved. reliability.

In the embodiment of this application, the capacity of the first battery unit is positively related to the maximum power that the server can provide. During the operation of the server, when the second power is less than the preset value, the first battery unit is charged. Please refer to Figure 4. Figure 4 is a schematic diagram of power consumption provided by an embodiment of the present application. It can be seen from Figure 3 that from 0s to the first moment, the second power is less than the first threshold, that is, the first AC-DC power conversion unit can independently power the power unit. At this stage, the first AC-DC power conversion unit The unit can also charge the first battery. As the remaining power of the first battery continues to increase, the total server power that the server can provide to the power-consuming unit continues to increase. From the first moment to the second moment, the second power is greater than the first threshold, and enters the stage where the first AC-DC conversion unit and the battery unit jointly supply power to the power unit through the first DPU. In this stage, the electric energy stored in the battery unit is consumed. As the power of the battery unit continues to be consumed, since the maximum power that the first AC-to-DC power conversion unit can provide to the power-consuming unit remains unchanged, the total server power that the server can provide to the power-consuming unit begins to decrease. After the third moment, the total power consumption of the power consumption unit and the second power are greater than the total power of the server. The server is overloaded. The management unit sends a load limit signal to the power consumption unit every 2 seconds, and the power consumption unit actively adjusts the power demand until the second power decreases. to below the total power of the server, and stops after the fourth moment. In the period shown in the figure, point A is the maximum energy storage point of the battery, and point B is the maximum power consumption point.

It should be noted that the description of power consumption in Figure 3 is only an example. In actual applications, the power consumption units in the server should be managed based on the first threshold in the actual situation and the power of the battery unit. There is no restriction here.

Based on the strict reliability requirements of the computer room, the embodiment of this application proposes to add additional servers on the basis of the aforementioned servers. The circuit simultaneously supplies power to the power-consuming unit. Please refer to Figure 5. Figure 5 is another structural schematic diagram of a server provided by an embodiment of the present application.

The server includes a first AC to DC power conversion unit 301, a second AC to DC power conversion unit 302, a first PDU 303, a second PDU 304, a first battery unit 305, a second battery unit 306 and a management unit 307.

Among them, the first AC to DC power conversion unit 301, the first PDU 303, the first battery unit 305 and the management unit 307 are similar to the connection relationships and actions performed in the server shown in Figure 3, and will not be described again here.

The second AC-to-DC conversion unit 302 is electrically connected to the second PDU 303, converts the 220v AC voltage provided by the computer room into a DC voltage, and uses the DC voltage to provide the second PDU 303 with the fourth power of electrical energy.

The second PDU 303 is electrically connected to the power consumption unit 205 and provides power to the power consumption unit 205 with the DC voltage.

When the second power (the sum of the rated powers of the power-consuming units) is less than or equal to the second threshold, all the electric energy provided by the second PDU 304 to the power-consuming unit 205 is provided by the second AC-to-DC power conversion unit 302 .

When the second power is greater than the second threshold, the electric energy provided by the second PDU 304 to the power consumption unit 205 is provided by the second AC-to-DC conversion unit 302 and the second battery unit 306 . Wherein, the second AC to DC power conversion unit 302 provides electrical energy with a fourth power, and the second battery unit 306 provides electrical energy with a fifth power. The fifth power is the difference between the second power and the fourth power.

The management unit 307 is electrically connected to the second AC-DC conversion unit 302, the second battery unit 306 and the second AC-DC conversion unit 302, and when the second power is greater than the second threshold, the output voltage of the second AC-DC conversion unit 302 is less than The output voltage of the second battery cell.

The management unit 307 obtains the remaining power of the second battery unit 306 and determines the upper power limit of the second battery unit 306 based on the remaining power of the second battery unit 306 .

When the fifth power is greater than the upper power limit of the second battery unit, the management unit 307 adjusts the power unit 205 to reduce the load of the power unit 205 and reduce the second power to ensure the normal operation of the power unit 205 .

The embodiment of the present application adds a set of power supply modules to the server so that the two sets of power supply modules can supply power to the power-consuming units at the same time, thereby reducing the impact of power failure on the equipment in the server and improving the security of the server.

When two sets of power supply modules supply power to the power-consuming unit at the same time, the power required by the power-consuming unit can be evenly distributed to the two sets of power supply modules, or can be supplied separately by one of the power supply modules. There are no specific restrictions here. .

The embodiment of the present application enables two sets of power supply modules in the server to evenly supply power to the power-consuming units, so that the two sets of power supply modules share the power supply pressure, further reducing the probability of a power outage in the server due to overpower.

The server provided by the embodiment of the present application has been introduced above. The power supply method provided by the present application will be introduced below with reference to the accompanying drawings.

603. The management unit sends the first signal to the AC-DC conversion unit;

When the second power is greater than or equal to the first threshold, the management unit sends a first signal to the AC-DC conversion unit, and the first signal instructs the AC-DC conversion unit and the battery unit to jointly power the PDU. After receiving the first signal sent by the management unit, the AC-DC conversion unit lowers the output voltage so that the output voltage of the AC-DC conversion unit is less than the rated voltage of the battery unit, so that the AC-DC conversion unit and the battery unit jointly supply power to the PDU. Effect.

604. The management unit sends the second signal to the AC-DC conversion unit;

When the second power is less than the first threshold, the management unit sends a second signal to the AC-to-DC conversion unit, and the second signal instructs the AC-to-DC conversion unit and the battery unit to jointly power the PDU. After receiving the second signal sent by the management unit, the AC-DC conversion unit increases the output voltage so that the output voltage of the AC-DC conversion unit is greater than the rated voltage of the battery unit, thereby achieving the effect of the AC-DC conversion unit supplying power to the PDU.

605. The management unit obtains the remaining power of the battery unit and learns the upper power limit of the battery unit based on the remaining power of the battery unit;

When the second power is greater than or equal to the first threshold, the server still provides electric energy of the second power to the power-consuming unit through the PDU, wherein the AC-to-DC conversion unit provides electric energy of the first power to the power-consuming unit through the PDU, and the battery unit uses the PDU. The power consumption unit provides the third power of electrical energy.

The server obtains the remaining power of the battery unit, and learns the upper power limit of the battery unit based on the preset relationship between the remaining power of the battery unit and the upper power limit of the battery unit, so as to facilitate subsequent adjustments to the server based on the upper power limit of the battery unit. Adjust the power consumption of the power-consuming unit.
