Hello Gustavo, well, I did not use Nutch at all, but I got some experience with using Solr.
In Solr you could use a multicore-setup where each core points to another hard-drive of your server. For other Solr-Servers ( and cores as well ) each core is a seperate index, so to query all drives of one server you have to do a distributed request to get all results from all cores (indizes). You got a little bit Http-overhead, because you have to send six http-requests per server to get your results. You could also set up 6 Solr-instances per box or 3 with two cores per instance, but I do not see any reason to do so. Could you please explain what you mean with "remote class search"? Is it a Nutch-specific thing I never heard before? There is no difference between a Lucene-Index created by Solr and a Lucene-Index created by Nutch or Lucene itself. Solr is just a Server-implementation of the Lucene-Framework.
