 Sharding partitions the data-set into discrete parts.
 Replication duplicates the data-set.
 These two things can stack since they're different. Using both means you will shard your data-set across multiple groups of replicas. Put another way, you Replicate shards; a data-set with no shards is a single 'shard'.

 A Mongo cluster with three shards and 3 replicas would have 9 nodes.

 3 sets of 3-node replicas.
 Each replica-set holds a single shard.
