Embodiment

[0027] The primary power supply adopts a group of 3+1 parallel redundant power supply mode, each power module is equipped with a rated output power of 5000W, and the total rated power can reach 15000W. All the modules run in parallel to bear the current load on average. When one module fails, the other modules will immediately support all the loads, making it continuously and uninterruptedly supply power to the RACK system. The primary power supply is designed with functional circuits such as fault detection, location, isolation, alarm, and hot replacement. When a fault occurs in the power supply subsystem, the management unit in the power supply sends information to the RMC to realize efficient monitoring and online maintenance functions; the first-level power supply subsystem is designed with various safety protection circuits such as overvoltage and overcurrent, The RMC monitors the abnormal conditions of the power supply itself and the system to take protective measures to...

Abstract

The invention provides a method for designing power supply of a centralized RACK system, which is characterized in that: a N+1 redundancy power source module is adopted to displace a +12V power supply bus via a middle power source backboard in order to supply power to a plurality of computation blade nodes, the power source module and the computation nodes are connected with the power source backboard all by means of golden fingers, wherein a primary power source is to convert alternating current 220V commercial power into 12V direct current, the 12V direct current is output to various servernodes in the system by means of 12V, a DC-DC secondary power source integrated with each server node performs the conversion, and 12V, 5V, 3.3V, 5VSB and -12V voltages required by the server nodes aswell as time sequence signals for switching on and off PS-ON and PowerGood are provided; a secondary power supply is to enhance the universality of motherboards of various server nodes in the RACK system and provide short-circuit protection for every server node in the RACK system, and upon the short-circuit failure of certain server node, the secondary power source is disconnected immediately and stops supplying power to the server node, thereby avoiding the power failure of the entire RACK system.

Description

technical field [0001] The invention relates to the field of power supply for server cabinet systems, in particular to a centralized RACK power supply method. Background technique [0002] The rapid development of the Internet has resulted in explosive growth of information resources. People use the Internet as a media, and their demand for information is also increasing. Various large-scale data computer rooms have also emerged as the times require. The number of individuals—servers and storage cabinets—that make up a data center is also increasing. As the amount of information increases, more cabinets cannot be deployed in the original computer room. Therefore, the mobile container data room came into being. The power supply of the RACK cabinet, the unit that makes up the mobile computer room, has become a difficult point. Therefore, this paper proposes a centralized RACK power supply design method. Contents of the invention [0003] The purpose of the present inven...
