What is a cluster?A computer cluster consists of a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system. If the captain is down then any other member takes its place automatically and starts managing the cluster, all the search heads are grouped together over the network. Any help is appreciated.
