I am setting up a Database environment with SQL server 2008 with two nodes in the cluster. Due to hardware reasons, I would like to set up a cluster with 1 node initially and when the second server is available I want to add it to the cluster. There are concerns in my team that adding a second node later requires lot of re-configurations, might be many complications, bla bla bla. So, I have the following questions for the experts, please help me out here..Thanks for your answers.
1. Is it possible to set up a cluster with 1 node?
2. How easy it is to add a second node to the cluster?
3. Will there be any downtime or performance issues, complications in adding second node at a later stage?
