What type of cluster configuration is best for indexing/bulk upload reliability?

I want to configure an Elasticsearch cluster so that indexing through bulk uploads are fast and reliable. The cluster will be made up on 6 nodes, but I'm unsure of which type of node handles indexing and bulk uploads, and how many of each node to configure. Should the majority of nodes be data nodes to reduce the likelihood of bulk uploads failing?
