Two stage electric power system of blade server

Abstract

The invention provides a secondary power supply system for blade server; the system adopts AC-DC or DC-DC system power supply as first power supply and outputs single 12V voltage, and adopts DC-DC on each function unit of the system as secondary power supply and finishes effective system power supply through two-level power supply; the system structure includes that: (1) a first power supply unit; (2) a secondary power supply unit; (3) a first-secondary power supply interconnection unit; wherein, (1) the first power supply unit is the basis of the system structure and controls the conversion of standard AC or DC power supply; (2) the secondary power supply unit is used for converting the first voltage into other voltage required by system modules; (3) the first-secondary power supply interconnection unit is a circuit for connecting the two-level power supply system.

Description

technical field [0001] The invention relates to a blade server, in particular to a secondary power supply system structure. Background technique [0002] Blade server is a new form of server product, and its development speed is very fast. Its typical feature is to integrate computing, storage, management, switching and other modules, and unify power supply and heat dissipation modules, so as to transfer servers, switches, and All kinds of connecting cables are integrated into one solution product. It can be seen that the blade server has strong vitality and broad development prospects. [0003] However, how to better design the power supply system structure of the blade server, ensure good power supply of each module, improve the design efficiency of the power supply system, and simplify the design of the system are the core and difficult points of the blade server design. [0004] Usually, the output of our traditional server system power supply has various voltages such...

Problems solved by technology

This makes the AC-DC conversion efficiency of the system power supply very low. At the same time, the output cables of the power supply are connected to the motherboard, hard disk, optical drive and other equipment. The cables in the system are difficult to clean, and the voltage loss on the cables is relatively large.

[0005] This traditional power supply method is no longer suitable for the blade server system, so it is necessary to further improve and optimize the power supply system, so as to improve the overall system architecture of the blade server.
