Start with a read of https://confluence.atlassian.com/adminjiraserver/jira-applications-installation-requirements-938846826.html

Then for some numbers, head over to https://confluence.atlassian.com/enterprise/jira-sizing-guide-461504623.html

I would not recommend reading the second until you've read the main part of the first one, and skimmed the expanding sections for some of the things you want to bear in mind while reading the second!  The first also has a lot of links out to other places you might find useful for your case that you won't know you want to read until you've read both!
