Fig. 1 is the schematic diagram of server according to embodiments of the present invention.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only the present invention's part embodiment, instead of whole embodiments. Based on the embodiment in the present invention, other embodiments all that those of ordinary skill in the art obtain, all belong to the scope of protection of the invention.

It is an object of the invention to provide a kind of server, it is possible to solve in conventional art, PCIe is connected by the problem that server space limits from equipment with mainboard, it is to increase the handiness that PCIe is connected from equipment with mainboard.

As shown in Figure 1, server according to embodiments of the present invention comprises:

Mainboard, and the PCIe primary device being arranged on mainboard, a PCIe slot, the 2nd PCIe slot and a PCIe are from equipment.

In embodiment in the prior art, the PCIe connector plugging slot on mainboard is used to slotting PCIe card, and PCIe card is integrated with Device equipment (namely PCIe is from equipment), the CPU on mainboard is HOST equipment (i.e. PCIe primary device). In existing scheme, HOST equipment is connected with PCIe slot, and Device equipment is connected with the golden finger on PCIe card, and that is, when PCIe card inserts in PCIe slot, Device equipment is connected with slot by golden finger thus is connected with HOST equipment.

In the present embodiment, HOST equipment is connected with PCIe slot, and Device equipment is connected with PCIe slot equally, in the present embodiment, mode of connection between equipment with PCIe slot can be connected by the signal wire arranged on mainboard, and wherein HOST equipment and Device equipment are all arranged on mainboard. In an embodiment, the signal wire interconnected between equipment and slot is integrated on mainboard. Especially, when Device equipment is connected with HOST equipment by needs by PCIe card, in the PCIe slot that can directly the insertion of PCIe card be connected with HOST equipment, thus the handiness that the primary device further increasing server is connected with between equipment.

Refer again to Fig. 1, in the present embodiment, being provided with two PCIeDevice equipment on mainboard, two equipment are connected with two PCIe slots respectively, in an embodiment, it is possible to by PCIe cable, PCIe is connected from the PCIe slot of the slot of equipment with CPUHOST equipment and PCIe primary device.
