Did you check that document: http://wiki.apache.org/solr/SolrCloud#A_little_about_SolrCores_and_CollectionsIt says: On a single instance, Solr has something called a SolrCore<http://wiki.apache.org/solr/SolrCore>that is essentially a single index. If you want multiple indexes, you create multiple SolrCores <http://wiki.apache.org/solr/SolrCores>. With SolrCloud, a single index can span multiple Solr instances. This means that a single index can be made up of multiple SolrCore<http://wiki.apache.org/solr/SolrCore>'s on different machines. We call all of these SolrCores<http://wiki.apache.org/solr/SolrCores>that make up one logical index a collection. A collection is a essentially a single index that spans many SolrCore<http://wiki.apache.org/solr/SolrCore>'s, both for index scaling as well as redundancy. If you wanted to move your 2 SolrCore <http://wiki.apache.org/solr/SolrCore> Solr setup to SolrCloud, you would have 2 collections, each made up of multiple individual SolrCores<http://wiki.apache.org/solr/SolrCores>.
