SharePoint 2016 Topology Planning

Question

Im trying to figure out how to properly size my SP 2016 farm(migration from SP2010), select proper roles for the servers etc.

I have two possible approaches in mind:

1. 8 Servers(2x each MinRole) plus SQL Servers
2. 4 Servers(2x each Shared Role(WFE + Distributed Cache/APP + Search)) - Similar to current 2010 scenario

I understand the benefits of it scenario but I having a little trouble figuring out which fits best the following scenario:

• 800~ Users
• 3 TB Data + growth of 30GB/month
• 4 WebApp, 80 site collections

Answer 1

For 800 users (more important, how many concurrent?), I would suggest the smaller of the two topologies for now using the shared MinRoles.

With the size of the index, I would suggest, in the future, looking at adding 2 or more additional Search servers (either App+Search, or stand alone Search).
