General hardware requirements?

[Nicholas Swarr <ns...@hotmail.com>]

Our index is about 10 gigs in size with about 3 million documents.  The documents range in size from dozens to hundreds of kilobytes.  Per week, we only get about 50k queries.
Currently, we use lucene and have one box for our indexer that has 32 gigs of memory and an 8 core CPU.  We have a pair of search boxes that have about 16 gigs of ram a piece and 8 core CPUs.  They hardly break a sweat.
We're looking to adopt Solr.  Should we consider changing our configuration at all?  Are there any other hardware considerations for adopting Solr?
Thanks,Nick

On the face of it, your machines should easily be adequate for the
the search volume you are looking at. However, there are other things
that you should consider:
* How are you indexing? What are acceptable times for this?
* Are there any new Solr-specific features that you are considering
  using, e.g., faceting? What performance benchmarks are you looking
  to achieve?
* What is your front-end for the search? Where is it running?
