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 defining characteristics:
•
They can be brought online and taken offline.
•
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 file
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
•
Virtual server name resources
