Network chip and a cloud server system

The invention discloses a network chip and a cloud server system. The network chip comprises a plurality of Ethernet NICs (network interface cards) and an Ethernet switch, wherein the plurality of NICs are connected with the Ethernet switch. The NICs and the Ethernet switch are integrated into a single network chip, and the cloud server system is built based on the chip. The structure of the cloud server system can meet the design requirements of a cloud server very well, that is, the performance per watt and the integrated service capacity are high, the cost and power consumption are low, and high performance is realized. Network virtualization is realized on the framework, and the performance of the server can be guaranteed to the largest extent.
