Description
Technical Field
The present invention relates to the field of computers, and more particularly to an intelligent network card and a data center.
Background
With the development of data centers, more and more businesses are cloud, and a lot of challenges are brought. In order to meet diversified customer requirements and further improve the reliability and the expansibility of the cloud data center, an intelligent network card technology is gradually developed. The intelligent network card is mainly used for unloading functions which are irrelevant to the service of a client and are arranged on a server, and comprises a virtual message exchange function, a network disk storage function and a message encryption function. These functions are generally characterized by simple logic, but occupy a large amount of resources of the server, so if the functions can be offloaded to a dedicated network card for processing, more resources on the server can be sold to the client for use. In addition, for many services such as bare metal, the intelligent network card is highly relied on as an access port of data traffic, and the whole framework building is realized.
The architecture of the intelligent network card is highly complex, and the reliability requirement on the intelligent network card is extremely high due to the special action of the intelligent network card in a data center. Therefore, the design key of the intelligent network card is how to design a product with high reliability under a high-complexity architecture.
The intelligent network cards of the server are designed independently. The outside is accessed into a core network of the data center through a network interface. With the design, each module on each intelligent network card works independently, and if a certain module on one card works abnormally, the whole server corresponding to the card cannot work normally. The traditional intelligent network card architecture has the advantages that the service depends on the normal work of a single card, when one network card fails, the whole server cannot work normally because the network card is used as an access of data flow, so that the traditional intelligent network card architecture cannot meet the requirement of high reliability, and has service risks for customers.
