Bind two NICs to increase access speed

Changing a gigabit Nic not only costs several hundred yuan, but also our switch is also a optical switch. Even if we change a gigabit Nic switch, we cannot change it! The problem has to be solved. I remember that many high-end server network cards can be bundled and used together through software when I purchased the server to achieve network access traffic distribution. Can common NICs bind them together?

Use NICExpress to bind two NICs, which can be used together with any brand or model. In this way, we can solve the problem of excessive network access pressure on a single Nic.

　　I. Preparations

The preparation is very simple. You just need to install two or more NICs on the server and install the driver. Generally, you can choose not to bind too many NICs based on the network load. Generally, it is recommended to bind 2-5 NICs, there are no excess PCI plug-ins available for your motherboard. In addition, to ensure the stability and performance of the bound Nic, we recommend that you use the NIC of the same brand and model as much as possible (you can quickly know whether the nic and the wireless Nic can coexist ).

　　Ii. installation settings

First, run the installation program. When the installation wizard prompts "Setup Type", select "Enabled" to enable network load balancing. When the data traffic is large, the software automatically distributes traffic so that each bound network card can take on a certain task, rather than putting the task on a certain network card (quickly know: the problem of integrating the network card ?).

TIPS: If it is Windwos XP, the following installation wizard may show that the hardware cannot pass the compatibility test. Click "continue" to continue.

According to the operation in the installation wizard, after the file is copied, the NIC binding setting window is displayed. The NIC installed on the computer is displayed at the top of the window, and the group name is in the middle, you can enter it directly. Now we need to select the multi-card to be bound in the list of network cards that have been installed above, click the "Add" button, and Add it to the "Assigned Adapters" box, the added Nic is the bound NIC (1). After adding the NIC, click "OK". A parameter setting window will pop up later, here, we recommend that you use the default program parameters (quick notice: Install the dual NIC Driver ).

Figure 13. Application settings

Now we can bind the network card to work. Open the "Network Neighbor" attribute window, we can see that on the basis of the original physical network card, there is another function out of a virtual network card (2 ). Right-click the NIC and select the "properties" command to open the NIC settings window. We can see that there is an "NIC Express Transport for Ethernet" in the installed components ", select this option and click the "properties" button to open the NIC binding window. Here we can add other bound NICs or delete the bound NICs; if you open the Properties window of "Internet Protocol (TCP/IP)", you can also set parameters such as the IP address of the virtual network card like a common network card (you can know: IP address conflict solution ).

Figure 2

TIPS: If the bound Nic has already set an IP address before binding, the program will prompt you whether to use the configured IP address during the binding process. In addition, we can also apply the bandwidth to different programs as needed. In http://www.bkjia.com/net/200811/30283.html, we will introduce the use of netlimiterto adjust bandwidth.

　　Iv. Comprehensive Application

Now we can connect the two network cables to the bound two network cards, then access the server through the IP address of the virtual network card, and perform operations, you can see that both NICs are performing data exchange on the NIC indicator (you can see that the network printer cannot be installed ).

In addition, you can go to the Start menu and choose NIC Express Enterprise Edition from the NICExpress installation page. In the displayed window, click the Settings tab to view network card traffic. If you want to view the traffic of a network card, you can Select it from the Select Device drop-down menu, and Scale is the traffic measurement unit, we recommend that you select "Mbits/Sec", that is, the number of megabytes per second, so as to compare the customer's traffic size from the right side (3 ).

If network load balancing is not enabled during installation, you can switch the window to the "Advanced" tab here, set "Load Balancing Disabled" under "Load Balancing Settings" to any other option (you can quickly know the relationship between QOS and Load Balancing ).

In fact, during the test, I found that NICExpress can effectively solve the problem of low network access speed caused by a nic, and it is also very stable. If you are confused, install Multiple NICs to balance the load of network access.
