Microsoft just released a great white paper on new support for multisite clusters in SQL Server 2012 for Disaster Recovery. Don’t forget that I blogged about this feature back in May of 2011 and even included a video demonstration which shows a SQL Server 2012 multisite failover cluster for disaster recovery using SteelEye DataKeeper Cluster Edition.

SQL Server 2012 and cross subnet failover capabilities will open up a whole new world of possibilities for people looking for disaster recovery options for SQL 2012.
