Product Documentation

System requirements

Sep 14, 2016

Introduction

The system requirements in this document were valid when this product version released; updates are made periodically. System requirements components not covered here (such as StoreFront, host systems, Citrix Receivers and plug-ins, and Provisioning Services) are described in their respective documentation.

Important: Review Prepare to install before beginning an installation.

Unless otherwise noted, the component installer deploys software prerequisites automatically (such as .NET and C++ packages) if the required versions are not detected on the machine. The Citrix installation media also contains some of this prerequisite software.

The installation media contains several third-party components. Before using the Citrix software, check for security updates from the third party, and install them.

The disk space values are estimates only, and are in addition to space needed for the product image, operating system, and other software.

If you install all the core components (Controller with SQL Server Express, Studio, Director, StoreFront, and Licensing) on a single server, you need a minimum of 4 GB of RAM to evaluate the product; more is recommended when running an environment for users. Performance will vary depending on your exact configuration, including the number of users, applications, desktops, and other factors.

For globalization information, see CTX119253.

Delivery Controller

Supported operating systems:

  • Windows Server 2016 current Technology Preview: Support for this operating system in this release is experimental and not for production use
  • Windows Server 2012 R2, Standard and Datacenter Editions
  • Windows Server 2012, Standard and Datacenter Editions
  • Windows Server 2008 R2 SP1, Standard, Enterprise, and Datacenter Editions

Requirements:

  • Microsoft .NET Framework 3.5.1 (Windows Server 2008 R2 only).

  • Visual C++ 2008 SP1 Redistributable package.
  • Disk space: 100 MB. 

The use of optional features increases disk space requirements. For example, the amount of space for connection leasing (which is enabled by default) depends on the number of users, applications, and the mode: 100,000 RDS users with 100 recently-used applications require approximately 3 GB for connection leases; deployments with more applications may require more space. For dedicated VDI desktops, 40,000 desktops require at least 400-500 MB. In any instance, Citrix suggests providing several GBs of additional space.

  • Microsoft Visual C++ 2008 SP1, 2010 SP1, and 2013 Runtimes (32-bit and 64-bit)

Remote PC Access uses this VDA, which you install on physical office PCs.

Several multimedia acceleration features (such as HDX MediaStream Windows Media Redirection) require that Microsoft Media Foundation be installed on the machine on which you install the VDA. If the machine does not have Media Foundation installed, the multimedia acceleration features will not be installed and will not work. Do not remove Media Foundation from the machine after installing the Citrix software; otherwise, users will not be able to log on to the machine. On most supported Windows desktop OS editions, Media Foundation support is already installed and cannot be removed. However, N editions do not include certain media-related technologies; you can obtain that software from Microsoft or a third party.

During VDA installation, you can choose to install the HDX 3D Pro version of the VDA for Windows Desktop OS. That version is particularly suited for use with DirectX and OpenGL-driven applications and with rich media such as video. Note that this is not supported for Windows 10. See the HDX 3D Pro section for additional support information.

You cannot install a current version of the VDA on a machine running Windows XP or Windows Vista; however, you can install an earlier Virtual Desktop Agent version on those operating systems if needed. See CTX140941 for details. The Remote PC Access version in this release is not supported on Windows Vista operating systems.

Virtual Delivery Agent (VDA) for Server OS

Supported operating systems:

  • Windows Server 2016 current Technology Preview: Support in this release is experimental and not for production use
  • Windows Server 2012 R2, Standard and Datacenter Editions
  • Windows Server 2012, Standard and Datacenter Editions
  • Windows Server 2008 R2 SP1, Standard, Enterprise, and Datacenter Editions

The installer automatically deploys the following requirements, which are also available on the Citrix installation media in the Support folders:

  • Microsoft .NET Framework 4.5.2 (4.6 is also supported)
  • Microsoft .NET Framework 3.5.1 (Windows Server 2008 R2 only)
  • Microsoft Visual C++ 2008 SP1, 2010 SP1, and 2013 Runtimes (32-bit and 64-bit)

The installer automatically installs and enables Remote Desktop Services role services, if they are not already installed and enabled.

Several multimedia acceleration features (such as HDX MediaStream Windows Media Redirection) require that the Microsoft Media Foundation be installed on the machine on which you install the VDA. If the machine does not have Media Foundation installed, the multimedia acceleration features will not be installed and will not work. Do not remove Media Foundation from the machine after installing the Citrix software; otherwise, users will not be able to log on to the machine. On most Windows Server 2012 R2, Windows Server 2012, and Windows Server 2008 R2 editions, the Media Foundation feature is installed through the Server Manager (for Windows Server 2012 R2 and Windows Server 2012: ServerMediaFoundation; for Windows Server 2008 R2: DesktopExperience). However, N editions do not include certain media-related technologies; you can obtain that software from Microsoft or a third party.

  • 32 bits per pixel
  • 1.5 GHz 32-bit or 64-bit processor
  • 1 GB RAM
  • 128 MB video memory on the graphic card or an integrated graphics processor

HDX queries the Windows device to verify that it has the required GPU capabilities, and then automatically reverts to server-side desktop composition if it does not. List the devices with the required GPU capabilities that do not meet the processor speed or RAM specifications in the GPO group for devices excluded from Desktop Composition Redirection.

The minimum available bandwidth is 1.5 Mbps; the recommended bandwidth is 5 Mbps. Those values incorporate end-to-end latency.

HDX Windows Media delivery

The following clients are supported for Windows Media client-side content fetching, Windows Media redirection, and realtime Windows Media multimedia transcoding: Citrix Receiver for Windows, Citrix Receiver for iOS, and Citrix Receiver for Linux.

To use Windows Media client-side content fetching on Windows 8 devices, set the Citrix Multimedia Redirector as a default program: in Control Panel > Programs > Default Programs > Set your default programs, select Citrix Multimedia Redirector and click either Set this program as default or Choose defaults for this program. GPU transcoding requires an NVIDIA CUDA-enabled GPU with Compute Capability 1.1 or higher; see http://developer.nvidia.com/cuda/cuda-gpus.

HDX Flash Redirection

The following clients and Adobe Flash Players are supported:

  • Citrix Receiver for Windows (for second generation Flash Redirection features) - Second generation Flash Redirection features require Adobe Flash Player for Other Browsers, sometimes referred to as an NPAPI  (Netscape Plugin Application Programming Interface) Flash Player.
  • Citrix Receiver for Linux (for second generation Flash Redirection features) - Second generation Flash Redirection features require Adobe Flash Player for other Linux or Adobe Flash Player for Ubuntu.
  • Citrix Online plug-in 12.1 (for legacy Flash Redirection features) - Legacy Flash Redirection features require Adobe Flash Player for Windows Internet Explorer (sometimes referred to as an ActiveX player).

The major version number of the Flash Player on the user device must be greater than or equal to the major version number of the Flash Player on the server. If an earlier version of the Flash Player is installed on the user device, or if the Flash Player cannot be installed on the user device, Flash content is rendered on the server.

The machines running VDAs require:

  • Adobe Flash Player for Windows Internet Explorer (the ActiveX player)
  • Internet Explorer 11 (in non-Modern UI mode). You can use Internet Explorer versions 7-10, but Microsoft supports (and Citrix recommends using) version 11. Flash redirection requires Internet Explorer on the server; with other browsers, Flash content is rendered on the server.
  • Protected mode disabled in Internet Explorer (Tools > Internet Options > Security tab > Enable Protected Mode check box cleared). Restart Internet Explorer to effect the change.

HDX 3D Pro

When installing a VDA for Windows Desktop OS, you can choose to install the HDX 3D Pro version (exception: machines running Windows 10).

The physical or virtual machine hosting the application can use GPU Passthrough or Virtual GPU (vGPU):

  • GPU Passthrough is available with Citrix XenServer. GPU Passthrough is also available with VMware vSphere and VMware ESX, where it is referred to as virtual Direct Graphics Acceleration (vDGA).
  • vGPU is available with Citrix XenServer and VMware vSphere; see www.citrix.com/go/vGPU (Citrix My Account credentials required).

Citrix recommends that the host computer have at least 4 GB of RAM and four virtual CPUs with a clock speed of 2.3 GHz or higher.
