Comparing Remote Desktop Virtualization Host (RDVH/VDI) & Remote Desktop Session Host (RDSH)

La question que l’on me pose tous les jours depuis la sortie du SP1 de Windows Server 2008 R2 à pour but de connaitre les bénéfices de remoteFX pour un serveur RDSH. Ci dessous, les bénéfices dans le cas d’un scénario de VDI et un scénario de RDSH :

RemoteFX w/ Remote Desktop Virtualization Host (RDVH/VDI) provides:
• Rich user experience for Virtual Desktop Infrastructure (VDI) via
- 3D virtual adapter
- intelligent codecs
- ability to redirect USB devices in virtual machines
• Requires (summarization - see above article for details)
- RemoteFX enabled on a Remote Desktop Virtualization Host server
- Windows 7 Enterprise/Ultimate running in a VM on the RemoteFX server
- RemoteFX compatible client
- Server-based GPU and other HW requirements as defined in this article
- Remote Desktop Connection performance set to LAN (10 Mbps or higher)
• Result: Full fidelity experience (e.g., 3D applications built on DirectX, Silverlight and Flash applications, etc.)

RemoteFX w/ Remote Desktop Session Host (RDSH/Terminal Server) provides:
• Rich user experience defined as:
- lower bandwidth usage as compared to Windows Server 2008 R2 when transferring rich graphics applications (i.e., intelligent codecs provide a better experience)
- Does not provide the same experience as RemoteFX w/ Remote Desktop Virtualization Host (RDVH/VDI)
• Does not provide:
- 3D virtual adapter
- ability to redirect USB devices in virtual machines
• Requires
- RemoteFX enabled on a Remote Desktop Session Host server
- RemoteFX compatible client
- Remote Desktop Connection performance set to LAN (10 Mbps or higher)
- No server-based GPU is required
• Result: Provides a better experience compared to Windows Server 2008 R2 without RemoteFX enabled but has fewer capabilites compared to RemoteFX w/ Remote Desktop Virtualization Host (RDVH/VDI).
