Lync Server 2013 supports virtualization topologies that support all Lync Server workloads, including instant messaging (IM) and presence, conferencing, Enterprise Voice, Monitoring, Archiving, and Persistent Chat. Running on virtualized servers requires Windows Server 2012 R2, Windows Server 2012, or Windows Server 2008 R2. . Note that Lync Server performance on virtual topologies can vary greatly depending on the workloads being used, the number of users, and the host hardware. We are currently running more detailed testing to provide more specific sizing guidelines.
Lync Server 2013 is supported on the Hyper-V platform, and on any virtualization platform that is supported under the Windows Server Virtualization Validation Program. For information on this program, see http://www.windowsservercatalog.com/svvp.aspx.
Virtual machine portability – the capability to move a virtual machine guest server from one physical host to another – is not supported in Lync Server. Moving a virtual server while it is in operation can cause functional errors in in Lync Pools. Lync Server has a rich set of application-specific high availability and failover techniques including data replication within a pool and between pools. Virtual machine-based failover techniques are not compatible with these application-specific capabilities.
Host servers should have hyperthreading disabled when hosting virtual servers running Lync Server 2013.
