308 IBM Systems Director Management Console: Introduction and Overview
12.3.1 Network requirements
Because data is continually replicated between the two cluster nodes, carefully
consider your networking topology. Figure 12-5 shows a diagram of a typical
SDMC High Availability environment.
Note that the SDMC provides network path redundancy through two connections
to each Flexible Service Processor (FSP) of a managed system. When the front
and back IPs of the FSP are connected through different networks to the SDMC
and one of the networks goes down, then the connection is automatically
established to the FSP from the same SDMC through the other network,
providing continuous availability to the user.
