Nokia IPSO 4.0 manual Example Cluster, 208

5

You can create IP clusters by combining flash-based platforms other than the IP2250 with disk- based or different flash-based models. For example, the following combinations are valid:

„flash-based IP1260, disk-based IP1260, IP380

„two flash-based IP1260 platforms

„IP385, IP380, IP265

This list provides examples only. There are many other combinations that you can use to create clusters.

Example Cluster

The following diagram shows a cluster with two nodes, firewall A and firewall B. The cluster balances inbound and outbound network traffic between the nodes. If an internal or external interface on one of the nodes fails, or if a node itself fails, the existing connections handled by the failed node are not dropped—the other node processes them. The other node continues to function and handle all of the traffic for the cluster.

Routers connected to an IPSO cluster must have appropriate static routes to pass traffic to the cluster. In this example:
