The value of ring_creation_size dictates how many partitions your Riak cluster will manage. These partitions are distributed amongst the nodes of your cluster. Each node in the cluster with manage a portion of the ring ( ring_creation_size / number of nodes ). A larger ring means each node will be responsible for more partitions which means each node will open more files (ulimit -n).
