In production clustering scenarios, you need to use more than one private network for cluster communication to avoid having a single point of failure. Cluster Service can use private networks for cluster status signals and cluster management. This provides more security than using a public network for these roles. In addition, you can use a public network for cluster management, or you can use a mixed network for both private and public communications.

In any case, verify that at least two networks are used for cluster communication; using a single network for node-to-node communication creates a potential single point of failure. We recommend that you use multiple networks, with at least one network conﬁgured as a private link between nodes and other connections through a public network. If you use more than one private network, make sure that each uses a different subnet, as Cluster Service recognizes only one network interface per subnet.

This document assumes that only two networks are in use. It describes how you can conﬁgure these networks as one mixed and one private network.
