Solr RAM size configuration

Hi,

I am running a solr cluster on AWS. And we chose instance types that
can hold the whole lucene index size in memory.  This was to avoid
swapping.

I am now reviewing this choice and have a question to better
understand solr RAM configuration.

Let's say I have a lucene index size of 80GB and ONE solr node only.
Can it be a consideration to have this solr node run on an instance of
32GB of RAM and a disc space > 200 GB?

In this example, the query per sec is 200 and queries are unique
(cache hit is low).

Thanks,
Moulay
