Nodes in a cluster all have similar characteristics, which
allows them to work together.
Cluster nodes include the following similarities:
- Every node has access to all cluster configuration data.
- Every node communicates with the other nodes in the cluster through
one or more physically independent networks (sometimes referred to
as interconnects). Network adapters, referred to in server
clusters as network interfaces, attach nodes to networks.
- Every node in the cluster is aware when another system joins or
leaves the cluster.
- Every node in the cluster is aware of the resources that are running
locally as well as the resources that are running the other cluster
nodes.
- All nodes in the cluster are grouped under the cluster name, which
is used to access and manage the cluster.
