AI Technical Summary

Technical Problem

The existing information transmission methods of DPU cards are incompatible with the hardware architectures of different manufacturers, resulting in the server being unable to obtain real-time information, the CPU and DPU processor being unable to transmit control information, and the existing solutions being unable to meet the high requirements for refined management.

Method used

A first connector and a first CPLD are set on the server motherboard, which are connected to the DPU through pin signal channels. The CPLD's programmable features are used to process and forward information, and non-real-time information is transmitted through the BMC and PCIe connectors, providing a compatibility solution for DPUs from multiple manufacturers.

Benefits of technology

It achieves compatibility in information transmission with DPU cards from different manufacturers, ensuring the transmission of real-time and non-real-time information, supporting the integration needs of DPUs from multiple manufacturers, and avoiding the need for motherboard hardware modifications.
