Once it is successfully installed and tested, then you can install SQL Server 2008 clustering. In this section, we take a high-level, step-by-step approach to installing and configuring Windows 2008 clustering.
Before you install Windows 2008 clustering, you need to perform a series of important steps. This is especially important if you didn't build the cluster nodes, as you want to ensure everything is working correctly before you begin the actual cluster installation. Once they are complete, then you can install Windows 2008 clustering. Here are the steps you must take:
