Description

Technical Field

[0001] This utility model relates to the field of computer technology, specifically to a combined server board. Background Technology

[0002] Currently, a typical 2U storage server board consists of a motherboard, mounting brackets, and a hard drive backplane. A typical 4U computing server board consists of a motherboard, mounting brackets, a hard drive backplane, and a PCIe switch board. 2U and 4U server motherboards are incompatible due to power requirements and external PCIe switches. Furthermore, due to chassis differences, even motherboards within the same 2U or 4U server category may differ and be incompatible. Therefore, different servers require individually designed motherboards, incurring significant time and manpower costs. Motherboards have high integration; if any circuit fails and cannot be repaired, the entire motherboard is rendered unusable, posing a significant risk. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a modular server board is provided to solve the problem that existing 2U and 4U server motherboards cannot be adapted to different servers and have poor versatility.

[0004] To achieve the above objectives, a modular server board is provided, comprising:

[0005] A general-purpose motherboard, on which a CPU, memory modules, and a CPLD are installed;

[0006] An expansion board is provided, on which a BMC and another CPLD are mounted. The signal interface of the expansion board is connected to the signal interface of the general-purpose motherboard via a high-speed connector. The power interface of the expansion board is connected to the power interface of the general-purpose motherboard via a power connector. The power interface of the expansion board is connected to a server power supply.

[0007] Furthermore, a network card is installed on the expansion board.

[0008] Furthermore, the expansion board is equipped with a PCIe expansion port.

[0009] Furthermore, the server power supply is a 2U server power supply or a 4U server power supply.

[0010] Furthermore, the high-speed connector is a 4C+ connector.

[0011] The beneficial effects of this invention are that the modular server board allows 2U and 4U servers to share a common motherboard. For different types of servers, only corresponding expansion boards need to be configured, avoiding redundant motherboard development, reducing development risks, and shortening the development cycle. If the expansion board is damaged and cannot be repaired, it can be directly replaced, and the motherboard can continue to be used, reducing cost waste.

[0012] The modular server board of this invention allows the same motherboard to be adapted to different servers, greatly enhancing the motherboard's versatility. At the same time, the expansion board offers flexible configuration and strong scalability. Attached Figure Description
