According to this link, these are the minimum requirements for running SharePoint 2013. http://technet.microsoft.com/en-us/library/cc262485.aspx. However, in talking to folks, some claim that it is possible to run a dev system a dev system with less RAM, etc. I realize what I am proposing is not an ideal setup, but I’d like to know if small business customers with fewer resources could actually run it on separate servers.
Basically, my question is: what's the minimum usable system spec for SharePoint 2013 you're using?
Has anyone tried running it on just 2 servers? If so, what are the specs and how many users are you serving?
