I recently had a chance to record a 33 minute podcast interview on RunAs Radio #281 with Richard Campbell, where I talked about the licensing changes in SQL Server 2012 and how to select your new hardware to minimize your SQL Server 2012 licensing costs. I also talked about Intel versus AMD processors, and talked about which Intel processors were good and bad choices for different workloads on SQL Server 2012.
RunAs Radio has been putting out weekly podcasts since April of 2007, and they have a lot of good content available there! Paul Randal and Kimberly Tripp did RunAs Radio #221 back in July 2011. Paul also did RunAs Radio #74 and RunAs Radio #72.
