Description

TECHNICAL FIELD

[0001] The present application relates to the field of mobile communication technology, in particular to a server power supply method and system. BACKGROUND

[0002] At present, there are two power supply modes for data center server cabinet power supply in the industry: independent power supply using general power distribution unit (PDU) and centralized power supply using power supply frame plus power supply copper bar.

[0003] The first kind: independent power supply using general PDU: mainly adopts PDU+server power supply, the main function of PDU is to distribute the input voltage 220V / 380V / 336V to the server, and the server power supply converts the input into direct current 12V to supply power to the server. Because of the need for redundancy power supply for server stability, two PDUs and two server power supplies are required. The specific power supply system block diagram is shown in Figure 1 .

[0004] The second kind: server power supply system using power supply frame plus power supply copper bar: the mainstream in the industry currently uses power supply frame plus power supply copper bar to connect the input voltage to the power supply frame composed of multiple power supplies, and the power supply frame converts the input voltage into 12V direct current voltage, which is transmitted to each server power supply unit through the power supply copper bar to directly supply power to the server.

[0005] The independent power supply system using general PDU requires two PDUs, and each server system in the cabinet needs two power supplies.

[0055] ​The AC-DC module is connected with the voltage and current detection module, and is used for converting the detected multi-path AC voltage signals into corresponding multi-path DC voltage signals respectively, and providing power supply signals for the multiple server systems respectively by using the multi-path DC voltage signals.

[0056] Optionally, the power distribution unit 11 in the present application comprises a voltage and current detection module and an AC-DC module. The voltage and current detection module is connected with the power input module 10 through an optical fiber, and detects the 220V / 380V AC voltage signal input by the power input module 10; the AC-DC module is connected with the voltage and current detection module through an optical fiber, and converts the detected 220V / 380V AC voltage signal into a DC voltage signal, and the converted multi-path DC voltage signal is used as the power supply signal of the multiple server systems 12 respectively.

[0063] For example, after the server power supply system provided by the present application is used to supply power to each of the plurality of server systems 12, the patch panel is connected to each of the plurality of server systems 12, and the DC voltage signals output by each of the plurality of server systems 12 and the 220V / 380V AC voltage signals detected by the voltage and current detection module are input to the cabinet control board. The cabinet control board detects the faults of the DC voltage signals output by each of the plurality of server systems 12 and the detected 220V / 380V AC voltage signals according to the rated output voltage and the rated input voltage of each of the plurality of server systems 12, and then finds the corresponding target server system that has a power supply fault according to the serial numbers of the plurality of server systems 12, so that the maintenance personnel can timely maintain.

[0064] The server power supply system provided by the present application can realize real-time detection of the current and voltage of the whole machine through the input current and voltage detection module and the cabinet control board, and can realize intelligent management of the server power supply system by realizing functions such as centralized power supply, whole cabinet current limiting, time-sharing power-on and power-off, and various operation and maintenance turntable management.

[0065] Further, in an embodiment, the patch panel can specifically include:

[0066] The board-to-board connector is used to connect to the plurality of server systems 12, so that the patch panel determines the serial numbers of the plurality of server systems 12 according to the board-to-board connector and the serial numbers of the board-to-board connector;

[0067] The serial numbers of the board-to-board connector are obtained after the patch panel numbers the board-to-board connector.

[0068] Optionally, in order to realize accurate management of each of the plurality of server systems 12, the patch panel is provided with a board-to-board connector, and the patch panel uniquely numbers (for example, ID numbers) each of the board-to-board connectors by using the resistance pull-up and pull-down function. The board-to-board connector is connected to the plurality of server systems 12, and the ID number of the board-to-board connector is used as the serial number of the plurality of server systems 12 connected thereto, so as to realize accurate control function of each of the plurality of server systems 12.

[0069] Board-to-board connectors: Used to precisely and repeatably connect printed circuit boards (PCBs) and electronic components containing conductive patterns printed on the surface of an insulating base. Each terminal on a board-to-board connector connects to a PCB. A board-to-board connector consists of a housing and a specific number of terminals. The terminals are made of conductive material and are electroplated to improve conductivity and rust resistance. The terminals transmit current / signals between the PCBs connected via the board-to-board connection. The housing is made of insulating material.

[0070] The server power supply system provided by this invention enables precise management of multiple server systems by physically uniquely numbering multiple server system nodes through a connector board.

[0071] Furthermore, in one embodiment, the board-to-board connectors are arranged on the connector plate at preset distance intervals.

[0072] To achieve precise management of each of the multiple server systems 12, a board-to-board connector is often set on the interface board at preset distance intervals (e.g., per U distance interval). Each board-to-board connector is connected to one or more server systems 12 using a fiber optic cable-free plug-in connection method to provide power to the multiple server systems 12 and to provide a connection path for management signals, so that maintenance personnel can promptly maintain the target server system that has malfunctioned based on the management signals between the management server and the multiple server systems 12.

[0073] In practical scenarios, server system 1 and server system 2 nodes are connected to the board-to-board connectors of the patch panel using a fiber optic-free plug-in connection. Each unit (U) of the patch panel has one board-to-board connector. The patch panel uses pull-up / pull-down resistors to assign IDs (IDs) to server system 1 and server system 2; for example, server system 1's ID is 0001 and server system 2's ID is 0002. The rack control board detects the DC voltage signals output by server system 1 and server system 2, as well as the AC voltage signals detected by the voltage and current detection module. Based on the rated input voltage, rated output voltage, and ID of each server system, the faulty server system is identified. This allows maintenance personnel to send control commands (in the form of management signals) through the management server. The control commands travel from the rack control board to the patch panel, and finally through the board-to-board connectors on the patch panel to establish a management signal connection between server system 1 and server system 2, thus enabling the power-off operation for the faulty server system 1 or server system 2.

[0075] Further, in one embodiment, the number of patch panels is one or more.

[0076] Optionally, the number of patch panel components can be one or more without affecting the implementation of the overall function of the server power supply system provided by the application, for example, when the number of multiple server systems 12 exceeds the maximum number of multiple server systems 12 that can be connected by one patch panel, multiple patch panels can be provided, and the patch panels can be connected in a plug-in manner.
