Hi, Let’s start from the top and introduce also Shards, Primaries and Replicas: SolrCluster is a cluster of Solr Nodes. Nodes are part of the same cluster if reading configuration from the same “folder” of the same Zookeeper ensemble (ensemble = cluster in ZK terminology). Node is the instance of Solr process - whenever you run “solr start -c…” you are starting a new Node. That is Jetty process hosting Solr servlet. Solr Cluster can hoste one or more Collections where collection is logical representation of an Index. Collection can be sharder to one or more Shards and each shard can have one or more copies called Replicas. One copy is declared as Primary and it can change. Each Replica is one Solr Core which is the same as Solr Index in standalone mode.
