You indicated in an earlier email that you expected half the nodes to be offline at any time. It is unclear how you expected that to work for either the consistency processes or the topology/placement processes. > I am trying to understand how to "set the dials" to ensure availability and > durability ...

Add in having half the nodes offline, and you can expect it simply not to function most of the time. Perhaps if you started from what your availability and durability requirements are the conversation would be simpler. b
