SCVMM RDV plug-in enables dynamic placement of VDI VMs for both personal and pooled VMs. The key benefit of using this plug-in is that it reduces the number of Hyper-V servers required since VMs are placed on demand rather than statically placed. Dynamic placement is achieved by integrating SCVMM 2008 R2 with the RDS Connection Broker in Windows Server 2008 R2.
Figure below shows the integration:

For those of you that don’t understand how this works Ill write a little process workflow so you understand.
1. The VDI client tries to connect to the last VM it was using via the Connection Broker.
2. The Broker, knowing where it was in the cluster, in communication with SCVMM, tries to wake the VM from a save state
3. Problem is that the server its trying to start the VM on is already at capacity and it cant start there
4. SCVMM gets involved as part of this and moves the VM to another node in the cluster based on its dynamic placement algorithm, via a SAN move
5. The Connection Broker is then told which host the VM is now on and running
6. The user connects to the VM
