Preparing Your Systems for Clustering 23
Configuring IPv4 Addresses for Cluster Nodes
Use the static IP address assignments for the network adapters used for the
cluster nodes.
NOTE: The IPv4 addresses in Table 2-2 are used as examples only.
Cluster node network
adapters
For cluster operation, two network adapters are required: one for
the public network (LAN/WAN) and another for the private
network (sharing heartbeat information between the nodes).
For more information on cabling your cluster hardware and the
storage array that you are using, see "
Cabling Your Cluster
Hardware" in the Dell Failover Cluster Hardware Installation
and Troubleshooting Guide for the specific storage array on
the Dell Support website at support.dell.com/manuals.
NOTE: To ensure operation during a DHCP server failure, use
static IP addresses.
