Configuring The Ip Addresses For The Private Network - Dell PowerEdge Cluster FE100 User Manual

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 Table 6-1 for the NICs
assigned to the private network.

Node 2
Node 3
Node 4
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
