Yesterday, I attended Kevin Cox' talk about database mirroring in SQL Server 2005. The event was organized by the SQL Server User Group Austria in Vienna, with Peter Koen (old UG lead) inviting Kevin, and Jaser Elmorsy (new UG lead) organizing it. Session description for the records: Database mirroring is a new SQL 2005 feature for high availability. What happens if you combine mirroring with other features, like snapshot and clustering? This presentation will teach you the basics of database mirroring, then will discuss some advanced topics for common solutions.
Kevin also pointed us to the SQLCAT blog - CAT being shorthand for Microsoft SQL Server Development Customer Advisory Team. The description as well as Kevin promised that they will be posting demanding scenarios and solutions to those in that very blog.
