In a failover configuration, the two units must have the same hardware configuration. They must be the
same model, have the same number and types of interfaces, and the same amount of RAM.
The two units do not have to have the same size Flash memory. If using units with different Flash
Note
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. If it does not,
configuration synchronization from the unit with the larger Flash memory to the unit with the smaller
Flash memory will fail.
For more information, see the Cisco Security Appliance Command Line Configuration Guide.
