COMMUNICATING BETWEEN A CLUSTER AND A NODE EXTERNAL TO THE CLUSTER

摘要

A technique includes, in response to receiving an inquiry from a first node external to a cluster in a server node of a cluster, communicating server authentication data to the first node. The technique includes evaluating the first node by communicating with the first node over a temporary network set up based at least in part on the server authentication data and selectively allowing the first node to join the cluster based at least in part on the evaluation.
