both the public and private networks, the minimum number of static IP addresses

required for a four-node clustering is nine—two for each NIC in the cluster nodes and

one for the cluster.

Cluster-aware applications running on the cluster may require additional IP addresses.

For example, Microsoft SQL Server requires at least one static IP address for the vir-

tual server (Microsoft SQL Server does not use the cluster's IP address). Also, each

cluster node containing Internet Information Server (IIS) that is configured for failover

requires a unique static IP address.

Configuring the IP Addresses for the Private Network

A PowerEdge Cluster FE100/FL100 Datacenter Server configuration requires at least

two NICs in each PowerEdge server (cluster node), with each NIC dedicated to one of

the following networks:

•Public network (local area network [LAN])

•Private network (node-to-node communications through the cluster interconnect)

Attaching two networks to the cluster enables fault tolerance for cluster communica-

tions. If the cluster interconnects fails, the cluster can still use the public network for

cluster communications.

The NICs installed in a cluster node must reside on different IP subnets with the

cluster interconnect assigned to a separate IP subnet or a different network ID than

the LAN subnet(s) used for a client connection.

Dell recommends using the static IP address assignments in Table6-1 for the NICs

assigned to the private network.

NOTE: The IP address assignments for the public LAN segments may vary according

to your network environment.

If multiple private network NICs are connected to a network switch, make sure that all

of the NICs connected to the private network have a unique IP address. For NICs con-

nected to the private network in any other cluster connected to the same switch, you

can continue the IP address assignment displayed in Table 6-1 by using 10.0.0.5 and

10.0.0.6, and continuing the address assignment scheme for any additional NICs con-

nected to a private network NIC in the same cluster.

The IP address assignments for the public network may vary according to your net-

work environment. If the IP assignments are set up correctly, all of the NIC resources
