In a post on Microsoft’s Office Communications Server blog, Jerome Berniere, senior program manager in the Office Communications group, said the company would support both a fully distributed virtualized topology across several hypervisors and a single server virtualized topology.
The topologies are supported on Windows Server 2008 Hyper-V and any Server Virtualization Validation Program (SVVP) certified partner solution.
Presence, Instant Messaging (including remote access, federation, and Public IM Connectivity) and Group Chat workloads are supported. The following server roles can be deployed:
· Front-End Servers
· Back-End SQL Server 2008 64 bits
· Group Chat Channel Servers
· Group Chat Compliance Servers
· Edge Access Servers
Berniere said possible quality issues with real-time media meant virtualization of other real-time workloads would not be supported. He said the affected services include Voice, Video, Live Meeting, and Desktop Sharing workloads. These workloads cannot be part of a virtualized environment.
Audio/Video/Web Conferencing servers, Audio/Video/Web Edge Conferencing servers, Dial-in Conferencing, Communicator Web Access, Enterprise Voice or Remote Call Control may not be deployed as part of the virtualized pool.
Microsoft released a white paper detailing its tested architecture.
