While searching over the internet, today I found this official document ( http://msdn.microsoft.com/en-us/library/ms143432.aspx ) from Microsoft. This document clearly mentions maximum capacity of SQL Server for possibly all features. On a personal note, I never faced a situation where any feature of SQL Server really “maxed-out” but received so many questions from others asking “what is the maximum database size of a SQL Server database etc…” So I thought to post it for as a quick reference. Hopefully this will be useful information to all.
