Before you can configure the cluster for the first time or add a server (node) to an existing failover cluster, you need to take the following preparatory steps:
- Install the Failover Clustering
feature: You must install the Failover Clustering feature on
any server that will become a server (node) in the cluster. For
more information, see Install the Failover
- Connect networks and storage: You must
connect the networks and storage that the nodes will use. For
- Validate the hardware configuration:
We strongly recommend that you validate your hardware configuration
(servers, network, and storage) before creating a cluster or adding
a node to a cluster. To validate, you run a wizard. For more
information, see Validate a New or
Existing Failover Cluster.
Microsoft supports a failover cluster solution only if the complete configuration (servers, network, and storage) can pass all tests in the Validate a Configuration Wizard. In addition, all hardware components in the solution must be marked as "Certified for Windows Server 2008 R2."
To see the preceding steps in the context of a checklist, see Checklist: Create a Failover Cluster.
The following topics describe how to create a failover cluster or add a server (node) to a failover cluster:

Points (Names and IP Addresses) in a Failover Cluster
- Create a New Failover
- Add a Server to a

Application for High Availability
