Hi Umesh, if you want to completely separate both Solr-instances for any reasons, feel free to do so. However *I* feel very comfortable with managing multiple SolrCores within the same ServletContainer-instance (i.e. Tomcat).
The only reasons why I ever setup multiple instances were security-considerations (client wanted to enforce separate access to both Solr-servers and different Solr-homes as well). The other reason was to try out multiple JVM-instances per machine, in order to check whether multiple JVM-instances with less RAM perform better than one JVM-instance with much RAM. Sometimes a multiple-JVM setup moved to production, sometimes not. In short: >So should I add new instances of solr or should I use muticore feature where > each core has its own index. As I tried to explain above: it depends.
