Setting up a Network Load Balanced Server Farm Using Windows 2008 R2
***This information is for historical purposes, support for Windows2008R2 is discontinued as of Jan. 1, 2018***
In this article, we will go through the steps involved in setting up a server pair for Network Load Balancing to support one of the Visual Software Products using Microsoft Windows Server 2008 R2. In this exercise, we will be working on two machines, CHICO and GUMMO. These two machines each have two network cards, both of which are attached to the local network. They have been pre-loaded with Windows 2008 R2 and all of the other roles and features they need to normally function have already been added. As an alternative to using separate network cards, you may also assign multiple IP numbers to the same network card.
Setting up applications
Once the server farm has been set up, you will want to make sure that:
- The SIF interface where XML messages are sent and received are set up to use the cluster IP number
- Administrative interfaces are set up not to use cluster interfaces. If you must have admin interfaces clustered, then create a separate cluster for them (go back to [[|]] and create one with "Single" affinity). You want to protect this IP number accordingly. Like most other applications with user interfaces, our administrative applications use sessions and work best when they "stay with" a given server during a user session.
Assigning multiple IP numbers to a single network card
- Open the "Network and Sharing Center"
- Choose the network card from the "View your active networks" section and click on the link to view its details
- From the status window, choose "Properties"
- From the "Properties" window, scroll down and select "Internet Protocol Version 4" and press "Properties"
- Press "Advanced" to add an additional IP number (you will see the existing IP number shown in this window)
- Press "Add"
- Enter the new IP number, press "Tab" (the Subnet mask will be filled in for you)
- Press "Add", "OK", "OK", "Close", "Close"
…and the network card should now have the extra IP address.
