Exchange 2007 Single Copy Cluster-based setup review

Exchange 2007 supports the Single Copy Clusters (SCC) type, which is more or less identical to the traditional active/passive clusters we know from previous versions of Exchange. This means that a SCC-based cluster only provides service failover and still has a single point of failure when it comes to the databases, unless a shared storage solution that provides redundancy via other means is used in the environment. An SCC-based cluster using a fault-tolerant SAN is just as good as a CCR-based cluster in terms of data availability, but such a solution is much more expensive than a CCR solution.

You are reading part 6 from "Managing an Exchange 2007 Single Copy Cluster (SCC) setup," excerpted from Chapter 8 of the book "How to Cheat at Configuring Exchange Server 2007: Including Outlook Web, Mobile, and Voice Access," by Henrik Walther, copyright 2007, published by Syngress, a division of Elsevier.
Exchange Server 2007 doesn't support active/active clusters anymore; only active/passive clusters are supported in Exchange 2007.

Although it's possible to move the cluster resource group between the nodes using the Cluster Administrator console, you should always do so (as is the case with CCR-based clusters) using the Move-ClusteredMailboxServer CMDlet because the Move Group task in the Cluster Administrator console isn't Exchange 2007 aware.
