We are pleased to announce official support for server virtualization for Office Communications Server 2007 R2.
We are introducing support for both a fully distributed virtualized topology across several hypervisors and for a single server virtualized topology. These topologies are supported on Windows Server 2008 Hyper-V and any Server Virtualization Validation Program (SVVP) certified partner solution (http://www.windowsservercatalog.com/svvp.aspx?svvppage=svvp.htm).
