For the moment, I have the following information:

12GB is max java heap. Total memory i don't know. No direct access to host.

2 replicas = 
        Size 1 = 11.51 GB
        Size 2 = 11.82 GB
(Sizes showed in the Core-Overview admin gui)

Thanks very much!

The size of the input data will have an effect on how big the index is, but it 
is not a direct indication of the index size.  The size of the index is more 
important than the size of the data that you send to Solr to create the index.

You say 12GB ... but is this total system memory, or the max Java heap size for 
Solr?  What are these two numbers for your servers?

If you go to the admin UI for one of these servers and look at the Overview 
page for all of the index cores it contains, you will be able to see how many 
documents and what size each index is on disk.  What are these numbers?  If the 
numbers are similar for all the servers, then I will only need to see it for 
one of them.

If the machine is running an OS like Linux that has the gnu top program, then I 
can see a lot of useful information from that program.  Run "top" 
(not htop or other variants), press shift-M to sort the list by memory, and 
grab a screenshot.  This will probably be an image file, so you'll need to find 
a file sharing site and give us a URL to access the file. Attachments rarely 
make it to the mailing list.
