Replica distribution across instances

I am just starting to explore Riak, so please bear with me if I'm
asking an obvious question: does anyone have a good method of
guaranteeing that replicas are placed across multiple Riak instances?

ring_creation_size > # instances to allow for expansion. However,
riak_claim:default_choose_claim/1 claims partitions at random, so
there is no guarantee that N neighboring partitions are not claimed by
the same instance. If that node then fails, data is lost. Have I
missed something here?
