2.3 Scenario - Installation in an Enterprise environment
2.3.1 Environment overview (network structure)
Below is a copy of the previous network structure with one additional branch office, several clients and one server
named LITTLE. Let’s suppose there is a slow VPN channel between the headquarters and the branch office. In this
scenario, the Mirror server should be installed on the server LITTLE. We will also install a second ERA Server on LITTLE
in order to create a more user-friendly environment and minimize the volume of transferred data.
