Understanding Your Failover Cluster
Cluster Objects
Cluster objects are the physical and logical units managed by a cluster. Each
object is associated with the following:
• Properties that define the object and its behavior within the cluster
• A set of cluster control codes used to manipulate the object's properties
• A set of object management functions to manage the object through

Cluster Networks
A cluster network provides a communications link between the cluster nodes
(private network), the client systems in a local area network (public network),
or a combination of the above (public-and-private network).
Preventing Network Failure
When you install the Failover Clustering feature provided by the Microsoft
Windows Server 2008 operating system, identify the public and private
network segments connected to your cluster nodes. To ensure cluster failover
and non-interrupted communications, perform the following procedures:
• Configure the private network for internal communications.
• Configure the public network for all communications to provide a
redundant path if all of the private networks fail.
• Configure subsequent network adapters for client system use only or for all
communications.
You can set priorities and roles of the networks when you install the Failover
Clustering feature.
