The embodiment of the invention provides PCIE equipment which comprises a service board and an expansion board, and the service board is connected with the expansion board; the expansion board is connected with the expansion equipment; and the service board is used for distributing various types of to-be-processed data to the expansion equipment connected with the expansion board for processing, and after processing is completed, the expansion board returns the processed data to the service board. The expansion board can be connected with a large number of expansion devices through PCIE interfaces. Therefore, PCIE connection between the service board and a large number of extension devices is established. Therefore, a novel PCIE connection architecture is established, and PCIE connection with the extension equipment can be established without a server. The problem that a large number of extension devices cannot be connected through a server is avoided.
