On January Microsoft released a webcast Level 200 I missed:
This Support WebCast talks about Microsoft SQL Server 2005 and the many new clustering features that it offers. This session discusses these new features. It also provides step-by-step instructions about how to install SQL Server 2005 clustering on Microsoft Windows Server 2003. This WebCast demonstrates all the installation steps using Microsoft Virtual Server configured as a Windows Server 2003 cluster.
Take a look at presentation slides here, download the video here, or watch it in streaming here.
Thanks to Virtualserver.tv for the news.
