This solution supports redundant LAN ports, the failure of central control (CC),
ADP, OpenScape 4000 Assistant and OpenScape 4000 CSTA. Also, the
OpenScape 4000 platform Administration (portal) will be switched over with ADP,
OpenScape 4000 Assistant and OpenScape 4000 CSTA.
The CCs run in hot standby mode and were supplied with continuous data and
status updates over the Atlantic LAN.
The ADP, OpenScape 4000 Assistant, OpenScape 4000 CSTA and OpenScape
4000 platform Administration (portal) run in warm standby mode and will be
restarted in case of failover.
The SWU failover is independent from a failover of the other services (ADP,
OpenScape 4000 Assistant, OpenScape 4000 CSTA, OpenScape 4000 Platform
Administration (NGP) and Integrated Display Telephone Book(DTB)).

In operation of a duplex configuration, the virtual machines of the ADP and the
OpenScape 4000 Assistant/OpenScape 4000 CSTA/OpenScape 4000 platform
Administration (portal) on the primary node are active, while the correspondant
virtual machines on the secondary node are offline. The ADP and the OpenScape
4000 Assistant/OpenScape 4000 CSTA/OpenScape 4000 platform
Administration (portal), which reside on the same node, can only change their
active/offline states together. Thus, an OpenScape 4000 Assistant/OpenScape
4000 CSTA/OpenScape 4000 platform Administration (portal) is only active on
that node on which the virtual machine for the ADP is active.
