     <para>The setup consists of two sub-clusters, placed in different
-    geographical locations. Each sub-cluster contains three MariaDB servers,
-    thus avoiding the split-brain problem. In this example, two of the
-    machines are running only MariaDB, while the rest are hosting a MariaDB
-    server and an Enea uCPE Manager instance. The entire network is hidden behind a
-    firewall that performs NAT. While in protection (cluster) mode, the
-    Enea uCPE Manager instances promote a Virtual IP (VIP) that represents the IP address of the
-    entire cluster. The firewall in this case will allocate a public IP for
-    the outside world that will be translated into the VIP. Also in this
-    example, the traffic towards the cluster from outside the firewall is done
-    through HTTPS, which will be translated to HTTP inside the private
-    network.</para>
