No dedicated NICs, the link speeds are fast enough to not really worry about this. It's also worth mentioning that in a cluster of N, to recover a node, it simply needs to stream 1/(N - 1) of the data from its neighboring nodes. So when you look at the cluster as a whole, and the strain on each node that is UP and serving traffic, it's insignificant.
