Do you mean all the components of the cluster or only the OSD-nodes? Before making the requirements i only read about mirroring clusters.

Splitting the network usually doesn't help. This is something i was told to do, because a reconstruction of failed OSDs/disks would have a heavy impact on the backend network. > > Paul > Thanks again.
