-"A cluster is a set of nodes that communicate with each other and work toward "
-"a common goal. In a JBoss Application Server cluster (also known as a "
-"“partition”), a node is an JBoss Application Server instance. Communication "
-"between the nodes is handled by the JGroups group communication library, "
-"with a JGroups Channel providing the core functionality of tracking who is "
-"in the cluster and reliably exchanging messages between the cluster members. "
-"JGroups channels with the same configuration and name have the ability to "
-"dynamically discover each other and form a group. This is why simply "
-"executing “run -c all” on two AS instances on the same network is enough for "
-"them to form a cluster – each AS starts a Channel (actually, several) with "
-"the same default configuration, so they dynamically discover each other and "
-"form a cluster. Nodes can be dynamically added to or removed from clusters "
-"at any time, simply by starting or stopping a Channel with a configuration "
-"and name that matches the other cluster members. In summary, a JBoss cluster "
-"is a set of AS server instances each of which is running an identically "
-"configured and named JGroups Channel."
