I followed the URL below to setup a SQL 2008 cluster and it is working and I am currently doing testing. I am currently installing a Web application with a SQL database. When I did the installation I was not able to put in the name of the SQL cluster which means there is no DNS entry. I ended up being the IP address of the SQL cluster which is working.
Before I put this into production I would like to know if I should create a DNS entry for it or always use the IP. I ask this because the web.config will now have the IP instead of the DNS name.
I am also a little confused as to which IPs do what, below is what I ended up with.
10.0.0.235 = Node1
10.0.0.236 = Node
10.0.0.237 = Cluster (I assume I would use this if I want to access whatever the primary node is?)
10.0.0.238 = MSDTC IP (not sure when if ever I would use this)
10.0.0.239 = SQL Cluster IP (I assume whenever I need to access SQL I use this?)
