Description

A Method of Realizing Equivalent PMBUS Function Using Common Single Power Supply

technical field

The invention relates to the field of computer power supply, in particular to a method for realizing equivalent PMBUS functions by using a common single power supply.

Background technique

In the recent wave of "energy saving and consumption reduction", the energy consumption of servers has been alleviated. Among the various methods of reducing energy consumption introduced by the industry, the most eye-catching one is the "dynamic power consumption node management" advocated by Intel (i.e. DPNM) technology, using this technology, you can set some strategies to control the dynamic power consumption of the server within a certain range. In order to achieve this goal, it is necessary to change the motherboard, operating system, BIOS and power supply, one of which is to require the power supply to have a PMBUS function (that is, the PMBUS power supply that is often said), that is, it can provide input power data to the server system.

Since the PMBUS power supply can provide input power data to the server system, it is more complex than the ordinary power supply, with more energy consumption acquisition, communication and other circuits centered on the control chip, as well as the corresponding underlying software, namely Firmware. This part of the circuit and software increases the cost of the power supply accordingly. Therefore, almost all PMBUS power supplies on the market are redundant power supplies. This is because, for power supply suppliers: if it is considered to be applied on a single power supply, then the cost ratio is about 10%-20%; if it is applied on a redundant power supply, the cost ratio can be reduced to 5% or even lower . But for server system manufacturers and end users, when they promote DPNM, they are more concerned about reducing its implementation cost. Therefore, the use of PMBUS redundant power supply is undoubtedly much more expensive than the use of PMBUS single power supply.

A method of realizing the PMBUS function with a single power supply is based on reality, using the idea of separating the main circuit of the power supply from the PMBUS circuit (that is, the PMBUS card), which not only realizes the lower-cost DPNM technology, but also brings practical economic benefits to customers. Benefits; It also achieves the effect of "one card with multiple (units) single batteries", which solves the problem that ordinary single batteries have no PMBUS function, and has great application value.

Contents of the invention

The purpose of the present invention is to provide a method for realizing the equivalent PMBUS function by using a common single power supply.

The purpose of the present invention is achieved in the following manner, including hardware and software, wherein the hardware includes a common power supply, a PMBUS card, a PMBUS interface and a server, and the PMBUS card is connected in series on the output wire that connects the common but power supply and the server. The circuit related to the PMBUS function in the power supply is separated and made into an independent and universal PMBUS card. The software only needs to modify its Firmware program and communicate with the server motherboard through the PMBUS interface, so that it can be matched with different ordinary single power supplies equivalent to PMBUS power supplies.

The invention has the beneficial effects of reducing the realization cost of the DPNM technology of the server system and solving the problem that a common single power supply has no PMBUS function, thus having good application value.
