Let me tell you how to choose a 10 Gigabit network card

With the continuous progress and development of the data center network , People's requirements for the speed of the network card are also increasing . From the previous 100 megabyte network card to the present 100G The network card speed has doubled 100 times . Of course, Gigabit and 10 Gigabit network cards are more popular in the market now . However, there are many types and manufacturers of 10 Gigabit network cards in the market , This makes users hesitate when buying network cards , I don't know how to choose . Today, Xiaobian will tell you about the chip 、 port 、 Network card functions and other aspects to explain some characteristics of 10 Gigabit network card .
One 、 chip
The realization of the network card function depends largely on the network card chip , The quality of the network card chip determines the speed of the network card 、 function 、 characteristic 、 And stability . Therefore, chip is the primary consideration when purchasing network card . Large manufacturers usually choose Intel This kind of chip network card , Can be the high quality of the network card 、 high stability 、 High compatibility provides reliable guarantee . Usually , The Gigabit network card uses i210、i350、i211 chip , The of 10 Gigabit network card is 82599、XL710、X550 chip ,XL710 Chips will also be used for higher transmission speeds 25G、40G NIC . Although the research and development of network card chip in China started late , But megacore 、 Godson and other brand enterprises have the strength of independent research and development of chips , It is also constantly consolidating the awareness of independent innovation , Increase China's control over chips and basic hardware .
Two 、 functional requirement
When purchasing a network card , Also consider whether the function of the product can meet your actual needs . Common functions of 10 Gigabit optical network card include QOS、VMDQ、SR-IOV、VLAN etc. , These capabilities apply to traditional or fully virtualized data centers . Some 10 Gigabit network cards also support some advanced functions , for example Infinibang function , This function can help users with server to server （ Like copying , Distributed work, etc ）, Servers and storage devices （ such as SAN And direct storage attachments ） And the communication between the server and the network . also DPDK function , This function can help users to Intel architecture(IA) Under the processor architecture, user space efficient packet processing provides function and driver support . It is recommended that you , Ensure that the 10 Gigabit optical network card can meet your functional requirements .
3、 ... and 、 port
At present, the number of ports of 10 Gigabit network cards on the market includes single port 、 Double port 、 Four , The dual port 10 Gigabit network card is the most common , When purchasing network cards, customers need to match 10 Gigabit network cards of different specifications according to the number of their own device ports . Of course , This does not mean that it is better to buy double port than single port . please remember , Only the right ones , Is the best , You need to make smart choices based on your specific network environment .
summary ： The above is a brief introduction to the 10 Gigabit network card , I hope that's helpful , If you want to buy a network card, you must choose an old brand that specializes in making network cards ISO authentication 、 Independent research and development 、 Only a manufacturer with its own factory can guarantee the quality , The pre-sales and after-sales service will also be of a very high standard , It will save us a lot of unnecessary trouble .
