A design architecture for a universal PSU module for cloud infrastructure

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to a Chinese patent application filed with the Patent Office of China on December 4, 2023, with application number 202311648128.4 and invention name “A design architecture of a universal PSU module for application in cloud infrastructure”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of hardware architecture design in server design, and in particular to a design architecture of a universal PSU module used in cloud infrastructure. Background Art

[0004] With the continuous evolution of information technology, cloud computing has rapidly flourished in recent years to meet the demands of application scenarios such as the Internet and big data, while also addressing the shortcomings of traditional IT architectures. Enterprises can use cloud computing to meet their IT development needs in a more intelligent and flexible manner. Due to its inherent technological advantages, cloud computing has gained widespread popularity and adoption. Cloud infrastructure, the hardware foundation of cloud computing, addresses many bottlenecks in traditional IT infrastructure architectures. Whether it's servers, storage devices, or switches within cloud infrastructure, mainstream equipment currently utilizes a modular design.

[0005] In the existing technology, the PSU module is the core unit of the cloud infrastructure equipment, and its main function is to provide power input to the equipment. The PSU module can be divided into different specifications and standards based on the three dimensions of structural size, interface definition and management protocol. The main PSU module standards in the cloud infrastructure currently include CRPS standard power supply, Huawei Kunpeng ecological power supply and customized PSU modules of various manufacturers. These PSUs are different in the structural size, interface definition and management protocol mentioned above. Therefore, different cloud infrastructure equipment will design corresponding structures and interfaces according to the specifications of the selected PSU module in the early stage of design to physically support the corresponding PSU module. At the same time, the software needs to adapt to the corresponding management protocol (as shown in Figure 1).

[0006] There are several problems with PSU modules in existing cloud infrastructure equipment:

[0007] 1. The structural dimensions are not uniform, and the structure cannot be shared. Cloud infrastructure equipment requires different structural designs to adapt to different PSU modules, increasing development costs.

[0008] 2. The software and hardware interfaces are not unified. Hardware boards with different interfaces need to be developed to use the corresponding PSU modules. Management software needs to be adapted to PSU modules of different specifications, increasing development costs.

[0009] 3. Due to the different update and replacement schedules of cloud infrastructure equipment, existing PSUs of different specifications are not compatible and can not be shared. This results in the inability to reuse PSU modules between cloud infrastructure equipment, and cannot reduce the asset and operating costs of cloud infrastructure equipment, which is not conducive to cost reduction and efficiency improvement of cloud infrastructure.

[0041] Module 3: The signal processing unit converts the communication signals of PSU modules of different specifications into universal PSU communication signals defined in this application, which mainly include address setting signals, management communication signals, in-position signals, enable signals, current sharing control signals and power supply status signals; by performing functional and protocol processing on the communication signals of PSU modules of different specifications, functional unification is achieved in the software communication protocol, providing a unified software interface for the sharing of universal PSU modules among different cloud infrastructure devices.

[0042] Module 4: Power supply unit, which connects the power supply signals of PSU modules of different specifications to the power supply pins of the universal PSU connector.

[0043] Module 5: Universal PSU connector, whose main function is to connect to cloud infrastructure devices. The universal PSU connector includes power supply pins and communication signal pins.
