Abstract

The invention relates to the technical field of servers, and provides a server board card capable of automatically identifying an external plug-in card and an external plug-in card automatic identification method, the server board card comprises a mainboard and an adapter card, the mainboard is provided with a platform control center PCH and two X8 connectors, and the adapter card is provided withtwo X8 connectors, a PCIe exchange chip and a slot identification circuit; wherein the slot identification circuit is connected with the PCIe exchange chip and the PCIe X8 slot, the slot identification circuit is used for identifying the insertion state of an external plug-in card of the PCIe X8 slot and feeding back the identified insertion state to the platform control center PCH and the PCIe exchange chip, and the platform control center PCH configures PCIe signals according to the identified insertion state of the PCIe X8 slot. Therefore, the identification of the type of the external plug-in card is realized, and the waste of manpower and material resources caused by designing two adapter cards for different configurations is avoided.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a server board capable of automatically identifying an external card and an automatic identification method for the external card. Background technique [0002] With the continuous development of server technology and the increase in the diversity of user needs, users have increasingly stringent requirements for the function and performance of a single server. The same server may need to support memory cards for machine storage expansion and require GPU is supported to support AI and artificial intelligence services, and network cards are also required to support network. Under normal circumstances, due to the size limitation of the server motherboard, the motherboard itself cannot be designed to support multiple PCIe external cards. Therefore, corresponding connector slots (such as PCIe slots) will be reserved on the motherboard during the server design process. , G...
