In production clustering scenarios, more than one private network for cluster
communication must be used 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. It is possible to use a public network for cluster management, or use a mixed
network for both private and public communications. In any case, make sure at
least two networks are used for cluster communication, as using a single network
for node-to-node communication represents a potential single point of failure. HP
recommends that multiple networks be used, with at least one network configured
as a private link between nodes and other connections through a public network. If
more than one private network exists, make sure that each uses a different subnet,
as Cluster service recognizes only one network interface per subnet.
This document is built on the assumption that only two networks are in use. It
shows how to configure these networks as one mixed and one private network.
The order in which the Cluster Service Configuration Wizard presents these
networks may vary. In this example, the public network is presented first.
