SQL2008 R2 cluster setup

I currently have a  single SQL2008R2 that I need to add redundancy too..
The failover server will be located at a different physical site, but the network segment,( 100Mb between sites) will still be within my Windows network security domain.(single domain for all sites)
I need it to be a passive failover.. Can anyone direct me to a good site that explains how to go from a single SQL Server to a failover cluster..


This is our payroll system and I need to have a backup site in case of a power outage or hardware failure..

Unfortunately, it's not possible to "upgrade" a stand-along instance to a clustered instance, but you'll instead have to configure a new SQL Server Failover cluster instance and then migrate your database there.

However, you can set up failover clustering on an existing server, cluster it with another server, and then install a new sql server instance and migrate your databases.

I've answered a similar question before and it still looks like it might address your needs:

Not sure I understand the question but I have a older PDF document I wrote on installing and configuring a SQL 2008 R2 2-Node cluster.

First, you have to enable Microsoft Clustering.  MSCS.  Technically has nothing to do with SQL Clustering.  It is a Microsoft Service that allows for clustering File Services, applications, and SQL.

That is the first prerequisite.  You need to pre-create a clustername on the domain.  You need two servers having two different names.  You enable MCSC on both servers, first.

Then you install SQL in cluster mode for 2-node cluster and run the prerequisite checks.

This will install the missing components after enabling MSCS.

If I had to summarize the steps it would be as follows: (My TOC)
