Noble,
Are you saying in the latest version of Solr that this would work with three
instances of Solr running on each server?
If so how?
Thanks again for your help.

I'm not sure if it is pertinent to ask you to move to the latest Solr
which has the policy based replica placement. Unfortunately, I don't
have any other solution I can think of

evaluating rules for replica placement, SolrCloud will treat each instance as
completely separate from all others, including others on the same machine. It
will not know that those three instances are on the same machine. One Solr
instance can handle MANY indexes.

be handled with multiple instances. That situation is this: When running one
instance would require a REALLY large heap. Garbage collection pauses can
become extreme in that situation, so some people will run multiple instances
that each have a smaller heap, and divide their indexes between them. In my
opinion, when you have enough index data on an instance that it requires a huge
heap, instead of running two or more instances on one server, it's time to add
more servers.
