RemoteFX

Last updated

Microsoft RemoteFX is a Microsoft brand name that covers a set of technologies that enhance visual experience of the Microsoft-developed remote display protocol Remote Desktop Protocol (RDP). [1] RemoteFX was first introduced in Windows Server 2008 R2 SP1 and is based on intellectual property that Microsoft acquired and continued to develop since acquiring Calista Technologies. [2] It is a part of the overall Remote Desktop Services workload.

History

Windows Server 2008 R2 SP1

RemoteFX components introduced in Windows Server 2008 R2 SP1 include:

Windows Server 2012

In Windows Server 2012, the following components were added to RemoteFX. [6]

In addition, the following components were updated:

Windows Server 2016, Windows 10 Enterprise

In Windows Server 2016 (RDP 10), the following components were added to RemoteFX. [13]

RemoteFX Media Streaming (H.264) replaced Multi Media Redirection (MMR). Note: MMR is now completely removed from RDP 10 given that RemoteFX Media Streaming works for all types of video content whereas MMR which just worked for some. [14]

RemoteFX vGPU Deprecation

Beginning in July 2020 RemoteFX vGPU was deprecated in all versions of Windows because of security vulnerabilities. It was scheduled to be completely removed in February 2021. [15]

Requirements

In Windows Server 2008 R2, the RemoteFX Codec could be leveraged for both session hosting (Remote Desktop Session Hosts) and VDI scenarios (and Remote Desktop Virtualization Hosts). The RemoteFX vGPU and RemoteFX USB Redirection features could only be used in VDI scenarios (Remote Desktop Virtualization Hosts). [16]

Windows 10 version 1511 brings RemoteFX to client Hyper-V, removing dependency on Remote Desktop Services role. [17]

Generation 2 VMs on Windows Server 2012 R2 do not support RemoteFX. [18] Windows Server 2016 added such support. [19]

In Windows Server 2012, all features of RemoteFX (with the exception of the vGPU) can be used with or without a physical GPU present in the server. [20] When no GPU is present in the server, a synthetic software-emulated GPU is used to render content. When a GPU is present in the server, it can be used to hardware accelerate the graphics via the RemoteFX vGPU feature.

RemoteFX vGPU Requirements

The RemoteFX vGPU has the following requirements: [21]

Windows Server 2008 R2 with SP1 has been tested for up to twelve virtual machines per GPU, for a total of twenty-four virtual machines on two physical GPUs. [21]

Although any GPU meeting the above requirements will be capable of using RemoteFX, the Windows Server Catalog carries an additional qualification to further define the requirements for server-qualified GPUs. These specifications define GPUs configuration requirements and provide VM performance targets. [24] Graphics cards that meet these are typically professional workstation products such as ATI/AMD's FirePro, v5800, v5900, v7800, v7900, v8800, v9800, and Nvidia's Quadro 2000, 3800, 4000, 4800, 5000, 5800, 6000, Quadro FX 2800M and 880M, QuadroPlex 7000 and Tesla M2070Q. [25]

Servers running the RemoteFX vGPU need to accommodate such graphics cards with either larger power supplies and more PCIe slots [26] or alternatively, connect existing servers to an external PCIe expansion chassis.

Guest OS requirements

The RemoteFX virtual graphics adapter is only supported by Enterprise editions of Windows, [27] starting from Windows 7 SP1. Other editions are missing the required drivers to use the RemoteFX graphics adapter and will fall back to the default emulated graphics adapter instead.

In computer networking, a thin client, sometimes called slim client or lean client, is a simple (low-performance) computer that has been optimized for establishing a remote connection with a server-based computing environment. They are sometimes known as network computers, or in their simplest form as zero clients. The server does most of the work, which can include launching software programs, performing calculations, and storing data. This contrasts with a rich client or a conventional personal computer; the former is also intended for working in a client–server model but has significant local processing power, while the latter aims to perform its function mostly locally.

In computing, the term remote desktop refers to a software- or operating system feature that allows a personal computer's desktop environment to be run remotely from one system, while being displayed on a separate client device. Remote desktop applications have varying features. Some allow attaching to an existing user's session and "remote controlling", either displaying the remote control session or blanking the screen. Taking over a desktop remotely is a form of remote administration.
