The past few weeks I have been busy playing with Exchange 2007 beta 2. There are many new (and dropped) features but I am especially interested in the CCR feature. CCR stands for cluster continuous replication. It is a new type of cluster that does not require any shared storage. You do need MSCS (Microsoft Cluster Server) which is a part of Windows Server 2003 Enterprise.

To be able to install a CCR cluster, you first need to install a Windows Server 2003 cluster that uses the MNS quorum type. MNS stands for majority node set. The complete process to install a CCR cluster can be found here . Note that this document does not necessarily follow best practices. It just documents the steps I followed to install such a cluster.

While I was playing around with this, the guys from the Exchange team have posted a blogcast of the whole process as well.
