If you use units with different Flash memory sizes in your failover configuration, make sure the unit with the smaller Flash memory has enough space to accommodate the software image files and the configuration files. Note: The two units do not need to have the same size Flash memory. They must be the same model, have the same number and types of interfaces, and the same amount of RAM. The two units in a failover configuration must have the same hardware configuration. Refer to the Cisco Security Appliance Command Reference, Version 7.2 for a more in-depth sense of the theory based behind this technology. This configuration guide provides a sample configuration to include a brief introduction to the PIX/ASA 7.x Active/Active technology. VPN failover is available only for Active/Standby Failover configurations in single context configurations. Note: VPN failover is not supported on units that run in multiple context mode as VPN is not supported in multiple context. Refer to PIX/ASA 7.x Active/Standby Failover Configuration Example in order to learn more information about the Active/Standby Failover configurations.

This document focuses on how to configure an Active/Active Failover in Cisco PIX/ASA Security Appliance. Both failover configurations support stateful or stateless (regular) failover. Active/Standby Failover is available on units that run in either single or multiple context mode. With Active/Standby Failover, only one unit passes traffic while the other unit waits in a standby state. Active/Active Failover is only available on units that run in multiple context mode. This lets you configure load balancing on your network.

With Active/Active Failover, both units can pass network traffic. Each failover configuration has its own method to determine and perform failover. The security appliance supports two failover configurations, Active/Active Failover and Active/Standby Failover. If those conditions are met, failover occurs. The health of the active interfaces and units is monitored to determine if specific failover conditions are met. The failover configuration requires two identical security appliances connected to each other through a dedicated failover link and, optionally, a stateful failover link.
