High availability of Windows Server2012 network

Before we talked about how to use Network Load Balancing to achieve high availability of web sites, my superficial understanding of the high availability is actually when a server crashes after a crash stop service, there will be another server spontaneously take over its work, to ensure that an application can continue to run normally, does not affect the provision of services.

Today I would like to introduce you to the highly available technology of the Windows server2012 network. It can also be said to be a dual NIC binding. What you have to say here is that the NIC teaming in Windows server2012, which is the 2012 new feature added, does not have this feature in Windows 2008 and previous versions of Windows2003, before 2012, If you want to implement this feature the system must take advantage of the software provided by the server, so say 2012 is convenient for us to achieve a high availability of the network. And the operation is very simple.

Let us experience the advantages of high availability of the network in the experiment.

1. Network Fault Tolerance

2. Bandwidth Binding

Experimental Environment : 1, we prepare two Windows Server R2 host, Server01, Server02.

2, Server01 for verifying network connectivity, IP:192.168.1.101/24

3. We have a highly available network deployment on the SERVER02. Server02 prepare at least two network cards and clear the existing configuration on the NIC.

After the experimental conditions were ready, we started the experiment, first we came to deploy the NIC high-availability server SERVER02, open the Server Manager-local server--nic combination, we can see it is now a disabled state, we open it for configuration, such as:

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image002 "border=" 0 "alt=" clip_ image002 "src=" http://s3.51cto.com/wyfs02/M00/6E/06/wKiom1VxQ9bhXGUMAAFg3LT9DkQ969.jpg "height=" 374 "/>

After we open NIC teaming, we click Group--task--new group,

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image004 "border=" 0 "alt=" clip_ image004 "src=" Http://s3.51cto.com/wyfs02/M01/6E/02/wKioL1VxRXSAi_EqAAGTLsMPQ8c250.jpg "height=" 509 "/>

I named team for the new group, the two blocks of the server I that check become a member of the group (if there are more than one network card to check all of them, the more network cards, to achieve greater fault tolerance), the group mode is selected as "Static Group", click OK. Such as:

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image005 "border=" 0 "alt=" clip_ image005 "src=" http://s3.51cto.com/wyfs02/M02/6E/02/wKioL1VxRXTx3aDfAAHCO2NTRso924.jpg "height=" 673 "/>

After clicking OK, our NIC teaming is configured so that two NICs are active, such as:

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image007 "border=" 0 "alt=" clip_ image007 "src=" http://s3.51cto.com/wyfs02/M02/6E/06/wKiom1VxQ9bRw48RAAGicUKBZ4E842.jpg "height=" 498 "/>

You can also see that NIC teaming is in an enabled state when you return to the local server. Such as:

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image009 "border=" 0 "alt=" clip_ image009 "src=" http://s3.51cto.com/wyfs02/M00/6E/06/wKiom1VxQ9bi7YdKAAGQtr3Nar8659.jpg "height=" 379 "/>

Below we click on the network adapter--network connection, we can see a piece of automatically added network card, we configure it for network IP:192.168.1.102/24, note: To and Server01 in a network segment, as shown:

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image011 "border=" 0 "alt=" clip_ image011 "src=" http://s3.51cto.com/wyfs02/M01/6E/06/wKiom1VxQ9fRGLMBAAGLtrfObxg264.jpg "height=" "/>"

The above for the network high-availability deployment is basically complete, below we came to Server01 machine on the network connectivity to verify.

We continue to ping 192.168.1.102–t at the command line, observing connectivity when the network is disconnected, such as:

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image013 "border=" 0 "alt=" clip_ image013 "src=" http://s3.51cto.com/wyfs02/M02/6E/06/wKiom1VxQ9eAD3HSAAKpkZEn7C8063.jpg "height=" "/>"

Let us first disable the first NIC on the Server02, and view the client's network connectivity, for example, network communication has no effect:

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image015 "border=" 0 "alt=" clip_ image015 "src=" http://s3.51cto.com/wyfs02/M00/6E/02/wKioL1VxRXXi7yMAAACxivLe6Zs796.jpg "height=" 312 "/>650" this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px;padding-right : 0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image017 "border=" 0 "alt=" clip_image017 "src=" Http://s3.51cto.com/wyfs02/M00/6E/06/wKiom1VxQ9eC0D0GAAHLKKQdAOk461.jpg "height=" 311 "/>

Next we turn on the first network card, disable the second NIC, return to the client again to see the network connectivity, the results of the network connection communication is still good, such as:

650) this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px; padding-right:0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image019 "border=" 0 "alt=" clip_ image019 "src=" http://s3.51cto.com/wyfs02/M01/6E/06/wKiom1VxQ9ezD_rPAACa8SoPve0316.jpg "height=" 311 "/>650" this.width=650; "Style=" background-image:none;border-bottom:0px;border-left:0px;padding-left:0px;padding-right : 0px;border-top:0px;border-right:0px;padding-top:0px; "title=" clip_image021 "border=" 0 "alt=" clip_image021 "src=" Http://s3.51cto.com/wyfs02/M02/6E/06/wKiom1VxQ9jQFM5QAAHcl3NfBNw000.jpg "height=" 319 "/>

The above experiment fully illustrates the network fault tolerance function of NIC combination, and realizes the high availability of network. The experiment is relatively simple, the network aspect is a more important link, the interested friend may according to this blog post oneself to build the experiment environment to do the experiment experience personally, extremely thanks everybody's view, hoped that everybody can put forward the opinion or the suggestion. What's the DA?!! ~~~~
