Cluster terms and components
Nodes
The most basic parts of a cluster are the servers, referred to as nodes. A server node is any individual
server in a cluster, or a member of the cluster.
Resources
Hardware and software components that are managed by the cluster service are called cluster resources.
Cluster resources have three de
fi
ning characteristics:
•
They can be brought online and taken of
fl
ine.
•
They can be managed in a cluster.
•
They can be owned by only one node at a time.
Examples of cluster resources are IP addresses, network names, physical disk resources, and
fi
le shares.
Resources represent individual system components. These resources are organized into groups and
managed as a group. Some resources are created automatically by the system and other resources
must be set up manually. Resource types include:
•
IP address resource
•
Cluster name resource
•
Cluster quorum disk resource
•
Physical disk resource
•
