Problems solved by technology

With more and more forms of single nodes, the higher the computing performance, the higher the power consumption; in this way, the 12V current in the copper bar will increase, and the loss will increase; The 12V at the input end of a single node will also produce a large voltage drop, which will increase the loss and affect the stability of the node
Moreover, currently only the voltage of 12V can be increased in advance, and there is no compensation mechanism

Embodiment Construction

[0012] In order to clearly illustrate the implementation of the design method, a further description will be made in conjunction with the drawings.

[0013] Such as figure 1 As shown, a PMBus bus is added between the PSU and the node. The node sends the collected node input voltage to the PSU through the PMBus bus. The PSU receives the voltage value sent by the node and automatically adjusts its own output to realize the PSU output voltage. Dynamic compensation. Due to the conduction of the copper bar, the voltage difference between the PSU output and the node input is caused, so that the node input voltage is in a stable and reliable range. Thus, the power supply stability of the system is enhanced.

[0014] The implementation steps are as follows:

[0015] 1) The hot-swappable controller for node power input needs to have PMBus monitoring function;

[0016] 2) Add a PMBus bus for PSU and node communication in the RACK topology;

[0017] 3) The PSU needs to be designed so that the ...

Abstract

The invention provides a method for compensating 12V voltage drop of a RACK server system, and relates to the field of RACK server power supply. According to the method, a node in a RACK is utilized for monitoring a PMBus of a power supply and communicates with PSU of the RACK, and current voltage of the node is fed back to the PSU through the PMBus; when the PSU receives a voltage signal from the current node, the output voltage of the PSU is automatically regulated according to the received voltage value to meet normal demands of the node on power supply voltage of the PSU; and therefore, automatic compensation of 12V voltage drop at the node end is realized.

Description

Technical field [0001] The invention relates to the field of server RACK power supply, in particular to a method for realizing the 12V voltage drop of a RACK cabinet server system. Background technique [0002] With the rapid development of the Internet and the advent of the era of cloud computing, users have increasingly demanded server customization. According to the different needs of users, the corresponding server forms (including: tower servers, rack servers, blade servers, rack cabinet products, etc.) and configurations are also different. Currently rack cabinet products are becoming the main products of data center servers. As there are more and more single-node forms, higher and higher computing performance will lead to higher and higher power consumption; in this way, the 12V current in the copper bar will become larger and larger, and the loss will increase; The 12V at the input of a single node will also produce a large voltage drop, which will increase the loss and...
