RemoteFX Support in Windows Server (Compact 7)
3/12/2014
When using RemoteFX in Windows Server 2008 R2 with SP1, you can deploy centralized virtual desktops running Windows that are hosted by a Hyper-V server. RemoteFX-enabled devices can provide a full, high-fidelity user experience. RemoteFX uses server hardware to encode data from either Remote Desktop Virtualization Host (RD Virtualization Host) or Remote Desktop Session Host (RD Session Host) role service in Remote Desktop Services before the data is sent to a device. RemoteFX supports scalable virtual desktop deployments by using graphics processing units (GPUs) and GPU virtualization. RemoteFX for Windows Server 2008 R2 with SP1 provides other Remote Desktop Connection (RDC) performance enhancements that are listed in the following section.
RemoteFX in Windows Server 2008 R2 with SP1 reduces the workload on RemoteFX-enabled RDC clients by using these features:
- Host-side rendering. Uses the RD Session Host or the RD Virtualization Host server, not the RDC client, to render graphics.
- GPU virtualization. Shares GPU hardware resources on the host server with RDC clients. GPU virtualization only works with virtual machines running on a Hyper-V server.
- Intelligent screen capture. Checks screen content between frames, and transmits for encoding, only the changes that the user made to the screen. It also tracks and adjusts network speed according to available bandwidth.
- RemoteFX Encoder. Encodes bitmaps for transfer from the RD Session Host server or RD Virtualization Host server to the RDC client. The RemoteFX Encoder compresses screen data by using the host CPU or GPU, or other dedicated hardware, such as an application-specific integrated circuit (ASIC).
