I'm trying to put together all the hardware specs for a enterprise/large scale HA SharePoint 2013 deployment. Unfortunately I'm having a hard time navigating the SP2013 deployment documents and finding those specs. I see minimums for small and medium but not much else. This topology would need to support up to 20K internal collaboration users and 20K external users with heavy traffic. I also need the hardware specs for each server role (Web,App,DB,Dev) being conservative to support heavy enterprise scale traffic. Rough number for starting capacity are below and we can expect that to grow at least 20%/year. Any help would be greatly appreciated.
Internal Collaboration:
20K users
4000 Site collections
9000 sites
External Collaboration:
20K users
300 site collections
1000 sites
