White Paper: Witness node in a StarWind-based environment
This document explains the benefits of the StarWind’s Witness feature. Clusters with an even amount of nodes are at high risk of experiencing total shutdown if half the nodes fail, so, usually, a physical Witness node is required to avoid downtime and split-brain. StarWind Node Majority Mechanism ensures constant uptime and high availability by setting up a minimum-requirements Witness node or a Witness instance in the cloud, so you don’t have to waste money on redundant hardware if you don’t want to.
