---------------------------------------------------------------
[~Sammi] If the topology is modeled as "*/d1/r1/ng/n*", will the cross rack
logic still work for replicas 3 and above? The current logic will choose the
second replica on the same NG but will the third replica correctly land on a
separate rack and not just separate NG?
