Lync Server virtualization
Lync Server 2010 is supported in a virtualized environment. The validated hypervisor can be Windows Server 2008 R2 [[Hyper-V]] or [[VMWare ESX]] 4.0, or any virtual environment that meets “Windows Server Virtualization Validation Program” at http://go.microsoft.com/fwlink/?linkid=200511.
Microsoft have published a white paper with full details of the support of virtualization
Lync Server enables the following workloads to be virtualized:
- [[Instant Messaging]] (IM)
- [[IM conferencing]]
- [[Presence]]
- [[Enterprise Voice]] (PSTN)
- [[Audio Conferencing]]
- [[Video Conferencing]]
- [[Web Conferencing]]
- [[Application Sharing]]
- [[Remote Access]], [[Federation]] ([[Edge Server]])
- [[Response Group service]]
A mixed pool of Front End servers comprising virtual and physical servers is not supported.
A single VM host with direct attached storage configuration.

| Small VM host configuration diagram |
Recommended networking:
· Dual network adapter/host: 1 network adapter reserved for host access, 1+ network adapter for shared VM guest application workload.
· network adapter speed: 1 GbE or 10 GbE (VMQ)
Recommended storage:
· Dedicated spindle for VM host, as well as a dedicated spindle for each VM guest virtual drive
Not recommended:
· 100 Mbps network adapters
· Single network adapter (for VM host and VM guest application workload)
· Shared spindles between host and guests, or between guests
Virtual Standard Edition Deployment
The most interesting deployment is a single virtual host with all roles required for a full implementation for 2000 users.
All virtual Standard Edition deployment, single Standard Edition server, with Archiving and Monitoring, SQL Server (Archiving and Monitoring), Edge Server (VLAN configuration to perimeter network)
Scale: 2K users, default usage profile, all modalities
