Server and data center

The invention provides a server and a data center, and relates to the technical field of cloud computing. The server comprises a data processing node and at least one computing node, the data processing node comprises a plurality of data processing unit (DPU) modules, the plurality of DPU modules of the data processing node are in communication connection, the computing node comprises a central processing unit (CPU) module, and the CPU module is in communication connection with each DPU module. According to the technical scheme provided by the embodiment of the invention, the single-path service transmission path of the server comprises the computing node taking the CPU module as the main part and the data processing node taking the DPU module as the main part, the plurality of DPU modules are configured on the single-path service transmission path, and the plurality of DPU modules form a redundancy architecture, so that the redundancy of the server is realized. Therefore, the influence of the DPU fault on th
