You may want to take a look at the wiki for SolrCloud:
http://wiki.apache.org/solr/SolrCloud/
But, you may just need a simple master-slave replication setup:
http://wiki.apache.org/solr/SolrReplication
SolrCloud is certainly preferred for large multi-shard, multi-replica
configurations, but that doesn't sound like your setup.
Think of a collection as the index data associated with a Solr schema. That
data could be replicated onto multiple cores and sharded onto multiple cores
as well, but it is all one collection. In addition, Solr provides support
for multiple collections, each of which has its own schema, replicas, and
shards.

Subject: Multi-core setup in Solr 4.0
Hi. I'm looking for a tutorial on how to set up two cores for a Solr 4.0
Beta instance. I've found this tutorial for earlier versions of Solr:
http://drupal.org/node/484800
Also, what are "Collections" in Solr 4? Are they related to cores? Thanks.
Sincerely,
Alex
