Cluster nodes

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 and 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.
