Description
Technical Field
The present invention relates to the field of power supply technologies, and in particular, to a method and an apparatus for dual input power supply.
Background
The server needs 365 days and 24 hours to operate continuously, the Power supply equipment of the machine room needs to be overhauled regularly, in order to guarantee the Power supply of the server during the overhaul period, two-way PDU (Power Distribution Unit) is configured in each cabinet to provide redundant Power supply, and the Power supply of one way PDU can be disconnected during the overhaul period. In order to avoid interruption of service operation of a server caused by a Power Supply Unit (PSU) failure, most servers configure PSUs according to a redundancy scheme.
The PSU is internally provided with a large-capacity electrolytic capacitor, the electrolytic capacitor can generate instantaneous large current called Inrush current when being charged at the moment of powering on the PSU, the Inrush current is related to the rated power of the PSU, the larger the rated power of the PSU is, the larger the Inrush current at the moment of powering on is, when a plurality of PSUs are powered on simultaneously, the Inrush currents are superposed, and the protective action of an air switch on a power supply line of the cabinet is triggered with probability, so that the power failure of the whole cabinet is caused.
With the increase of the update speed of the hardware devices of the servers, the demands of the servers on power supply capacity and power supply reliability are also increased, and the number of PSUs included in a single server and the rated power of a single PSU are gradually increased. The increase of the number of the PSUs increases the cost, and the increase of the rated power of the PSUs provides a new test for the power supply system of the traditional machine room.
For the PSU redundancy configuration of a server system, there are two redundancy methods at present, assuming that at least N PSUs are required to meet the service power requirement of the server, one method is to add N PSUs of the same number, which is called N + N redundancy, and the other method is to add only one PSU, which is called N +1 redundancy.
The first disadvantage of N + N redundancy is high cost, for example, a highly configured server needs 4 PSUs to maintain service operation, each PSU costs about two thousand yuan, the N + N redundancy scheme needs 4 extra redundant power supplies, and the power supply scheme cost of a single server increases eight thousand yuan. The second disadvantage of the N + N redundancy is that, when PDU is switched over, the PSUs need to be powered on again, the Inrush current superposed by multiple PSUs is too large, and air switch protection is easily triggered, so that the power failure of the whole cabinet is caused.
The N +1 redundancy has the disadvantage of being incapable of adapting to PDU power switching during machine room maintenance, for example, a server of a 4+1 redundancy scheme, when any path of PDU is powered down, a PSU connected to another path of PDU cannot meet the service power supply requirement of the server, therefore, the N +1 redundancy is also called as pseudo-redundancy, the redundancy scheme can only avoid the influence caused by PSU failure, cannot adapt to the maintenance requirement of dual-path PDU switching, cannot resist the failure of abnormal power down of a single-path PDU, and has lower power supply reliability.

In view of the above object, in a first aspect of the embodiments of the present invention, an embodiment of a method for dual input power supply is provided. Fig. 1 shows a schematic block diagram of an embodiment of a method of dual input powering according to the invention. In the embodiment shown in fig. 1, the method comprises at least the following steps:

The invention is explained by taking the machine room server as an embodiment, and the scheme can be expanded and applied to all equipment operation scenes with high requirements on power supply reliability.
In some embodiments of the present invention, fig. 4 is a logic block diagram of control signals of an embodiment of a method for dual-input power supply according to the present invention, and as shown in fig. 4, the whole power supply transformation scheme includes a central controller, 1 cabinet controller in each cabinet, 1 dual-input conversion unit corresponding to each PSU, and 1 module controller, 2 input control relays (first relay and second relay), and 1 output control relay (third relay) in each dual-input conversion unit. The central controller is in a core position in the system and is connected with the cabinet controllers in all the cabinets in the machine room through the Ethernet. And the cabinet controller in each cabinet is connected with the module controllers in all the double-input conversion units in the cabinet through a Can bus. And the module controller in each double-input conversion unit controls two power input numerical control relays and one power output numerical control relay in the module through TTL level. When the module controller outputs TTL high level to the numerical control relay, the numerical control relay is switched on, and when the module controller outputs TTL low level, the numerical control relay is switched off. The input interface of the double-input conversion unit is connected with PDU (first PDU and second PDU) through a power line, and the output interface is connected with PSU through the power line, thereby realizing the hierarchical control of the central controller to each relay through the network of Ethernet, CAN and TTL.
FIG. 5 is a control flow diagram illustrating the connection of 3 PSUs per PDU in a conventional power control scheme of the prior art; fig. 6 is a schematic diagram showing Inrush currents in a conventional power supply control scheme in the prior art, where each PDU is connected to 3 PSUs, as shown in fig. 5 and 6, according to the conventional cabinet power supply scheme, a central control system of a machine room can only control power-on and power-off times of each PDU in a cabinet, after a server is installed and connected, at the moment of power-on of a PDU and at the moment of switching between two paths of PDUs, all PSUs connected to the PDU are powered on at the same time, the Inrush currents are superimposed, and air switch protection is triggered by probability. In some embodiments of the invention, according to the power supply scheme of the invention, each PSU can simultaneously get power from two paths of PDUs (namely, a first PDU and a second PDU) through a dual-input conversion unit, if one path of PDU is in maintenance power failure or fault power failure, the PSU can continue to get power from the other path of PDU, and the server can be compatible with machine room power maintenance switching only by using N +1 power supply redundancy configuration, and prevent single-path PDU power supply fault risk, thereby effectively avoiding the defects of the conventional N +1 scheme. When the server system is started for the first time, the central control system firstly controls the two paths of PDU to be electrified, then the servers in each cabinet are sequentially started according to the sequence, and each server is sequentially electrified, so that the power grid fluctuation of the whole power supply of the machine room can be reduced, and the device loss of the power supply system of the machine room is reduced. In addition, because the PSU is simultaneously connected with the first PDU and the second PDU, the control system enables the output of the double-input conversion unit after the first PDU and the second PDU are both electrified, Inrush current at the moment of electrifying the PSU can be evenly distributed to the two PDUs, the Inrush current pressure born by each PDU is half of the pressure born by the PSU, the Inrush current when the system is started for the first time is effectively reduced, and the power failure of the whole cabinet is avoided.

And controlling the power supply path between the redundant PSU and the corresponding double-input conversion unit to be disconnected so that the redundant PSU is in a non-working state under the condition of normal power supply.

Fig. 3 is a schematic structural diagram of a dual-input conversion unit according to an embodiment of the dual-input power supply method of the present invention, and as shown in fig. 3, 701 is an output interface; 706 and 707 are input interfaces, wherein 706 denotes a first input interface and 707 denotes a second input interface; 702. 704, 705 are numerical control relays, wherein 702 represents a third relay, 704 represents a first relay, and 705 represents a second relay; 703 is a communication control unit.
According to some embodiments of the dual input powered method of the present invention, the method further comprises:
the output interface in each dual-input conversion unit is respectively connected with the corresponding PSU of the dual-input conversion unit, and the on or off of the output interface is controlled through a third register to control whether the corresponding PSU works or not.
In some embodiments of the present invention, the output interface is connected to the PSU through a power line, the communication control module is connected to the third relay through a data line, and the third relay can control whether the third relay is turned on or off according to the input high and low levels, so as to control the on/off of the output interface by the communication control module.
According to some embodiments of the dual input powered method of the present invention, the method further comprises:
sending a power supply instruction to a communication control unit in a double-input conversion unit through a controller;
responding to a power supply instruction received by the communication control unit, and controlling the level of the first register, the level of the second register and the level of the third register according to the power supply instruction;
the on or off of the first input interface is controlled by the level of the first register, the on or off of the second input interface is controlled by the level of the second register, and the on or off of the output interface is controlled by the level of the third register.
In some embodiments of the invention, the input interface of the dual-input conversion unit is connected with the PDU through a power line, the communication control module is connected with the first relay and the second relay through a data line, and the numerical control relay can control whether the first relay and the second relay are conducted according to the input high and low levels, so that the on-off control of the input interface by the communication control module is realized.
In some embodiments of the invention, the system further comprises a machine room central control system and a whole machine room power control algorithm in the system. The machine room control system sends an instruction to a server power supply controller on the cabinet through a wireless network, and the server power supply controller sends an instruction to a communication control module in the input conversion module through a signal line, so that the central control system controls the interface in each dual-input conversion unit.
According to some embodiments of the dual input powered method of the present invention, the method further comprises:
in response to receiving a power supply instruction for switching between the first PDU and the second PDU to supply power to a preset PSU, controlling the PSU to be disconnected from a corresponding dual-input conversion unit;

In some embodiments of the present invention, when a certain path of power supply in the machine room needs to be overhauled, the central control system sends an instruction, sequentially causes the dual-input conversion units connected to each PSU to sequentially turn off the connection between the PSU and the overhaul path PDU, so that the power supply pressure can be gradually and sequentially transferred to the non-overhaul path PDU. Compared with the traditional N + N redundancy scheme, after one path of PDU is closed, all power is instantaneously and simultaneously transferred to the other path of PDU, so that the power supply fluctuation of the other path of PDU is large.
In some embodiments of the present invention, for a conventional N + N redundant power supply scheme, load balancing of two PDUs mainly depends on a load current sharing function of the PSUs that are redundant with each other. However, the load current-sharing accuracy of the PSUs is limited, and due to batch reasons, the current-sharing accuracy of some PSUs is inevitably poor, and the traditional scheme lacks an effective processing scheme for the imbalance of the power supply of the two paths of PDUs caused by the current-sharing accuracy. According to the scheme provided by the invention, if the central control system detects that the power supply of the two paths of PDU (protocol data units) is unbalanced, the central control system can control the double-input conversion unit to disconnect the PSU from the PDU with higher load, so that the overall load balance of the first PDU and the second PDU can be intelligently adjusted in real time.
