Problems solved by technology

In a fault-tolerant server with high power, N+N redundancy of power supply will require more power supplies than N+1 redundancy, which will make the power supply system too large, the number of power supplies will be large, the reliability will be reduced, and the cost will also increase

Embodiment Construction

[0045] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. It should be understood that the following examples are only used to illustrate and explain the present invention, but not to limit the technical solution of the present invention.

[0046] Such as figure 2 As shown, it shows an embodiment of the system for realizing power supply redundancy of the present invention, assuming that the current fault-tolerant server load is 3KW, and the power of a single power supply module is 1KW; four power supply modules are used, which is 3+1 redundancy.

[0047]In addition to the above-mentioned system embodiment including two power distribution modules that divide one AC power supply into multiple AC power supply voltages and multiple power supply modules that perform AC-DC conversion and provide DC power to the load module, it also includes an AC detection module, a monitoring mod...

Abstract

The invention discloses a system and a method for achieving power redundancy. The system includes: an alternate current detection module detects input state of an alternate current input end of one path and outputs the detected state information to a monitoring module; the monitoring module controls switching on or off of a switch in a switch module according to the input state information; and the switch module controls connection or disconnection between alternate current power voltage distributed by a power distribution module and a power module through the switching on or off of the switch. The system and the method can achieve single path alternate current input and double path alternate current redundancy input simultaneously under N+1 redundancy configuration of the power supply, does not need to increase quantity of power supplies and simultaneously improves reliability of a power system and reduces cost under the premise of meeting requirements for alternate current redundancy input of a fault-tolerance server.

Description

technical field [0001] The invention relates to a power supply redundancy technology of a fault-tolerant server, in particular to a system and a method for realizing power supply redundancy. Background technique [0002] In order to achieve high availability of high-end fault-tolerant servers, high redundancy of equipment is usually required to reduce single point failures, so the power supply system of equipment is required to achieve AC redundancy and DC redundancy. [0003] In addition, from the perspective of data center security, its power supply is usually divided into the following 4-level power supply redundancy scheme: [0004] A: Tier1, N power supply scheme, no redundancy; [0005] B: Tier2, N+1 power supply scheme, with redundancy; [0006] C: Tier3, 2N, redundant power supply scheme for synchronous maintenance; [0007] D: Tier4, 2N+1, fault-tolerant redundant power supply solution. [0008] Currently, the new generation of data centers generally adopt the a...
