It is communicated according to transmission, to meet the information communication of server product big data quantity.However in certain actual project development process
In, it is either not applied to PCIE the OCP interfaces of external network interface card on certain specific mainboards, is connect at this time with standard
The network interface card of mouth, which just cannot be satisfied, to be patched on mainboard, to which mainboard just can not be with the extraneous transmission or reception for carrying out big data quantity.
In addition, in the server, it is prodigious to need the data volume transmitted, therefore the net for application in the server
Card, also has its transmission rate very high requirement.The network card data transmission rate of certain server is probably in 10G or so at present,
It can no longer meet the data transportation requirements of server, it is therefore desirable to network interface card rate is improved, fully to satisfy the use demand.
Utility model content
The technical problems to be solved in the utility model is：On certain special server master boards, if not supporting standard
PCIE OCP interfaces external network interface card when, how to realize and extend network interface card using non-standard high-speed interface external connection, together
When for certain server, the traffic rate for improving network interface card is also the technical issues that need to address.
In view of the above-mentioned problems, the utility model provides a kind of 40G rate network interface cards for supporting non-standard interface.
Technical solution used by the utility model is：

Facilitate PCB design.Simultaneously in cost, relatively traditional PCIE slot also have certain advantage.
Described to support that the 40G rate network interface cards of non-standard interface are IB network interface cards, it can not only support 40G ethernet communications,
It also supports the infiniband performances of 56G simultaneously, and for common network interface card, it can support RDMA（Reduced
Direct Memory Access）Technology can effectively reduce network delay, while can reduce CPU's by this technology
Load.
IB network interface cards, InfiniBand network interface cards, Infiniband architecture are that a kind of support mostly concurrently links " Convertion cable "
Technology, in this technique, each links the speed of service that can reach 2.5 Gbps.This framework linked at one when
It is 500 MB/ second to wait speed, and speed is 2 GB/ seconds when four links, and 12 speed when link can reach 6 GB
/ the second.
The SPI Flash are responsible for storing the basic configuration information for including firmware code of network interface card, after startup of server
Load configuration is carried out to network chip and interface.Wherein, SPI：Serial PeripheralInterface serial peripherals connect
Mouthful.
The EEPROM（Electrically Erasable Programmable Read Only Memory electrically erasables
Except read-only memory）It is responsible for the basic use information of storage board, to facilitate mainboard to be read out by I2C.
The network chip chooses ConnectX3 Pro chips, which supports 4 data transmission channels, each to transmit
Channel can meet the transmission rate of maximum 10G, therefore the chip highest is capable of providing the network communication rate of 40G, this
Rate can fully meet certain server to extraneous message transmission rate demand, while in cost, which also has one
Fixed advantage.
The network interface is using the network interface QSFP for supporting 40G transmission rates（Quad Small Form-factor
Pluggable four-way small pluggable interfaces）, the data transmission of this high-speed network adapter is made to be implemented as possibility.
The beneficial effects of the utility model are：
The utility model can use under certain specific application environments, not have when on certain server mainboard especially
When the external network card interface of the PCIE or OCP of offer standard, the mass data transmission in server and the external world just cannot achieve, at this time
The network interface card that must select to support non-standard interface, else if carry out larger variation to mainboard, can cause it is time-consuming and laborious, even
Generate some unpredictable consequences；Meanwhile for some servers, the network transmission speed of 1G/10G is far from
