Cluster Installation 7-19

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.
