Configuring IP Addresses for the Private Network
Dell recommends using the static IP address assignments for the NICs used for the private network (cluster interconnect). The IP addresses in
Table 2-2 are given as examples only.
Table 2-2. Examples of IP Address Assignments
Usage Cluster Node 1 Cluster Node 2
Public network static IP address (for client and domain controller communications) 192.168.1.101 192.168.1.102
Public network subnet mask 255.255.255.0 255.255.255.0
Private network static IP address cluster interconnect (for node-to-node
communications)
10.0.0.1 10.0.0.2
Private network subnet mask 255.255.255.0 255.255.255.0
Default gateway 192.168.1.1 192.168.1.1
WINS servers Primary 192.168.1.11
Secondary
192.168.1.12
Primary 192.168.1.11
Secondary
192.168.1.12
DNS servers Primary 192.168.1.21
Secondary
192.168.1.22
Primary 192.168.1.21
Secondary
192.168.1.22
NOTE: Dell recommends that you do not configure a default gateway, WINS, and DNS on your private network.
If multiple cluster interconnect NICs are connected to a network switch, ensure that all of the private network NICs have a unique address.
You can continue the IP address scheme in Table 2-2 with 10.0.0.3, 10.0.0.4, and so on for the private network NICs of the other clusters
connected to the same switch.
Additional fault tolerance for the LAN segments can be achieved by using NICs that support adapter teaming or by having multiple LAN
segments. To avoid communication problems in the private network, Dell recommends that you do not use dual-port NICs for the cluster
interconnect.
Creating Separate Subnets for the Public and Private Networks
The public and private network NICs installed in the same cluster node must reside on separate IP subnetworks. Therefore, the private
network used to exchange heartbeat information between the cluster nodes must have a separate IP subnet or a different network ID than
the public network, which is used for client connections.
Setting the Network Interface Binding Order
1. Click the Start button, select Control Panel, and then double-click Network Connections.
2. From the Advanced menu, click Advanced Settings.
The Advanced Settings window appears.
3. In the Connections box, click the connection you need to modify.
4. Click the up-arrow or down-arrow to adjust the connection priority.
5. Click OK.
Using Dual-Port NICs for the Private Network
You can configure your cluster to use the public network as a failover for private network communications. However, dual-port NICs are not
supported in the private network.
