Load balancing a private network

You can set up Dispatcher and the TCP server machines using a private network. This configuration can reduce the contention on the public or external network that can affect performance.

Before you begin

To create a private network, each machine must have at least two LAN cards, with one of the cards connected to the private network. You must also configure the second LAN card on a different subnet.

Example of a private network using Dispatcher

About this task

When you configure a private network, the Load Balancer machine will then send the client requests to the TCP server machines through this network.

[AIX] For AIX systems, this configuration can also take advantage of the fast speeds of the SP™ High Performance Switch if you are running Dispatcher and the TCP server machines on nodes in an SP Frame.

Procedure

The servers added using the dscontrol server add command must be added using the private network addresses. For example, a sample command could be coded as:
dscontrol server add cluster_address@80@10.0.0.1
not as
dscontrol server add cluster_address@80@9.67.131.18
