If you want good performance and enough memory to give Solr the heap it will need, yes. Lucene (the search API that Solr uses) relies on good operating system caching for the index. Having enough memory to catch the ENTIRE index is not usually required, but it is recommended. Alternatively, you can add a lot more hosts and create a new collection with a lot more shards. The total memory requirement across the whole cloud won't go down, but each host won't require as much. Thanks, Shawn
