A Great WhitePaper from MVP Paul Keely about SQL Server 2012 with System Center 2012 R2 on Windows Server 2012 R2.

In this guide Paul Keely has decided to be very much more focused on SQL and its interaction with System Center and indeed Server 2012. In the last guide he felt that a lot of people were already installing SQL for quite some time and there was a lot of knowledge out there on SQL installs but not best practices. SQL 2012 and Server 2012 have brought some real game changers to the story, and because of that this guide is going to go into way more detail on areas like setup and some of the options we have here. We are not going to walk you through a basic SQL setup, there are a ton of guides for that on the internet, instead we are going to look at some of the more complex areas like clustering, AlwaysOn, Storage Spaces and SQL Azure. If you are new to this subject then Paul suggest that you download the guide and use in in conjunction to this one.
