What’s New in XenApp & XenDesktop 7.13

The following content is a brief and unofficial prerequisites guide to setup, configure and test delivering virtual apps and desktops powered by XenApp & XenDesktop 7.13 prior to deploying in a PoC, Pilot or Production environment by the author of this entry. The views, opinions and concepts expressed are those by the author of this entry only and do not necessarily conform to industry descriptions or best practises. The views expressed here are my own and do not necessarily reflect the views of Citrix.

What’s New
A full and complete list of what’s new is avaiable at – I’ll start with one of my Citrix passions which is any and everything surrounding HDX technologies.

1. HDX Adaptive Transport is disabled by default in XAD 7.13* also referred to as EDT is a new HDX graphics mode that utilises both the UDP and TCP protocols with a fallback to TCP where UDP isn’t available. The HDX engineering team have engineered this new Citrix protocol called Enlightened Data Transport (EDT) which utilises the existing Citrix ports 1494 (ICA/HDX) and 2598 (Session Reliability) for both TCP and now new UDP so f/w ACL changes are near enough straight forward. To test this new graphics mode internally:

– Configure the ACL between your test end-point and through your internal network (over a VPN) VM running the 7.13 VDA to allow UDP and TCP for 1494, 2598
– Your test VM instance could be running in Azure (connected on-prem via a VPN) or on XenServer 7.1 and remember must be running the latest desktop or server VDA
– Your test end-point must be running the following min Citrix Receiver versions for Windows 4.7, Mac 12.4 and for iOS 7.2
– *In Studio create a machine catalogue, delivery group or use an existing one with your VDA upgraded from e.g 7.12 to 7.13 and then create a new HDX policy e.g HDX-TestofEDT and select the following HDX policy entitled “” and choose “Preferred“.

2. AMD Multiuser GPU (MxGPU e.g GPU Virtualization works with vSphere only) on the AMD FirePro S-series server cards for HDX 3D Pro workloads only e.g Desktop OSes ref – with support for up to 6 monitors, custom blanking & resolution, high frame rate and only GPU Pass-through is supported on the following hypervisors XenServer and Hyper-V. For further details please ref to the AMD website at –

3. Intel Iris Pro (5-6th Gen Intel Xeon Processor E3) graphics processors supports H.264 h/w encoding for virtual apps & desktops, HDX 3D Pro support for up to 3x monitors (Ref to install options+), custom blanking & resolution, high frame rate. For further details and compatible Intel processors ref to –

4. Other HDX enhancements include:

– Bidirectional content redirection –
– Wacom tablets improvements & connection methods – and also see
– File copying performance enhancements for client drive mapping

5. StoreFront 3.9 support for the following below and for a closer look check out the following CTX blog article –

– HDX Adaptive Display
– CEIP automatic enrollment by default. To disable please ref to
– Importing of NUG configurations (ZIP file or via PowerShell) into StoreFront to setup through the XAD Wizard using the latest NetScaler UG ref – to reduce and avoid misconfigurations.
– Not new but if you’re looking to security harden your StoreFront standalone or cluster ref to –
– SAML auth through against your preferred Store with NetScaler Unified Gateway configured as your IdP –

5. The Connection Quality Indicator is not part of the XAD 7.13 release but an invaluable Citrix tool for Citrix SysAdmins check out its capabilities at – and you can download it from – and it also inclues group policies for better SysAdmin controls to enable or disable the tool which is supported from XAD 7.6 LTSR and upwards ref the CTX220774 article. The below image is taken from a Window 10 virtual desktop powered by XenDesktop 7.x.

6. Linux Seamless published applications from a Linux supported OS using the 7.13 VDA – and also please read the publishing apps for Linux at – for advanced tips and guidance on seamless mode vs. window manger configuration.
7. LHC in 7.13 introduces a new support feature for brokering operations for Citrix Cloud when the internet connection between the Citrix Cloud Connector and the Citrix Cloud control plane at – is in a failed state or unavailable due to an ISP outage. You can also force an outage following the documentation available at – by creating and manually modifying the following registry entry “HKLM\Software\Citrix\DesktopServer\LHC with entry of OutageModeForced” set to the value in the documentation++ to force an outage for testing and or evaluation purposes prior to implmenting Local Host Cache. I’ve embedded below a simple architectural recap of LHC introdcued in XAD 7.12 and you can read in more depth detail about Local Host Cache from a previous blog post available at –

Finally LHC still provides support for brokering operations for traditional XAD Controller Site Database on-prem ref ++. I’d also recommend that you watch this TechTalks To Go covering LHC in XAD 7.12 release.

8. Provisioning Services 7.13 now supports Linux streaming and a brand new caching technique only available and supported on XenServer 7.1 called PVS-Accelerator. Check the following YouTube video from Citrix entitled “Introducing PVS-Accelerator, only available with XenServer!” via

9. HDX Thinwire enhancements in 7.13 have resulted in up to 60% bandwidth savings. Take a look at the following CTX blog post at – which has some great high level LoginVSI 4.1.6 graphics comparing Thinwire in 7.12 vs. 7.13 on Windows Server 2012 R2 and 2016.
10. AppDNA what’s new ref – now includes support for Windows 10 Anniversary Update (AU) and now defaultor analysis and reporting, Secure Web reports and finally improved importing to process to analysis OSes and apps. There are a few more to be sure to check out the whats news!

Deploying XenApp 7.13 for Evaluation & Testing Purposes
The fastest way to deploy and test the latest new features from Citrix XA 7.13 release with little to no effort is to deploy the “Citrix XenApp 7.13 Trial” from Microsoft Azure available and accessiable at –

The views expressed here are my own and do not necessarily reflect the views of Citrix.

Shortened Names

What’s New
1. vGPU for XenApp is now supported ref the following blog article published entitled “Citrix supports NVIDIA GRID™ vGPU™ for XenApp!” –
2. XenServer 6.5 can now support up to 3x nVidia GRID cards scaling up to 96 VM’s with a vGPU assigned in a GRID enabled/compatible supported server hardware.
3. nVidia have certified new GRID profiles all of which are Q certified check them out at –
4. The latest GRID card datasheet is avaiable at –

What is vGPU?
It is a logical portion of a physical GPU assigned to a VM to deliver rich graphical applications from either a multi-user or desktop OSes. It is currently only supported with either nVidia GRID K1/K2 cards, compatible HCL server running either XenServer 6.2 SP+ or XenServer 6.5+ with XenApp or XenDesktop 7.6. The GPU resources (Frame buffer) + access time that is allocated to a vGPU assigned to the VM is managed with the help of a vGPU profile e.g K120Q which manages the GPU resources + time in conjunction with the vGPU manager which is installed within Dom0 of the XenServer 6.2 SP1+ or 6.5 host which intern allows for any VM assigned a vGPU to handle and delivery graphical intensive applications e.g AutoCAD Map 3D or Adobe Photoshop CS. For more technical information and an alternative description and overview including a diagram checkout – on the nVidia website.

GRID Card History
The first generation of GRID cards were called K1, K2 Cards and made use of the “Kepler” architecture, technical details can be found on the datasheet here –

The second generation of nVidia GRID cards are called TESLA which make use of the “Maxwell” architecture which includes 3x offerings TESLA M10 (Rack Servers), TESLA M6 (MXM Blade Servers) and TESLA M60 (Rack Servers)

Overview of Citrix HDX vs. HDX 3D Pro
HDX stands of High Definition eXperience and is built upon the ICA protocol which is developed, owned and maintained by Citrix. HDX automatically and dynamically adapts to any changes within the users ICA session end-2-end to ensure that the users experience always comes first and foremost. HDX inspects the computing resources within the data centre e.g. the VM or physical server that the desktop or server VDA is install on, the network and the end-point device to see what computing resources can be leveraged to offload onto to further enhance the users experience. For a technical overview to Citrix’s HDX technologies and policies in XAD 7.6 check out – Citrix has published document entitled “What is HDX? / Citrix HDX technologies for optimizing the virtualization experience” available at – which provides a great introduction into HDX technologies.

vGPU Pre-requites & System Requirements
1. Start by reviewing
2. Hardware requirements can be found at – and to purchase a GRID enabled server please visit –
3. I would suggest downloading and reviewing the guide entitled “Part 1: XenServer GPU Pass-through” available at – prior to starting as this will cover off the installation of a GRID card into a Dell R720 Server which will be useful to review if your about to embark on deploying your first GRID K1/2 card in a compatible supported server.
4. The following guide entitled “Part 3: XenServer GPU Virtualization (vGPU)” covers off the full deployment from installing and configuring XenServer 6.2 SP1+ to preparing the VM and assigning a vGPU through to the installation and configuration of the nVidia GRID drivers, XenTools and the Desktop OS VDA. The guide is available at – *
5. Encoding method suggested is H.264 although you do need more power server h/w as this protocol type does require more computing power but uses less bandwidth and you’ll also require an end point capable of decoding the H.264 stream.

Installation & Configuration
1. or refer to point 4 in the above “vGPU Pre-requites & System Requirements” section.
2. NVIDIA GRID Configuration Checks by Jason Southern at nVidia

HDX 3D Pro Policy or Policies
1. I would strongly recommend when you begin your testing of a vGPU VM(s) that you create a new custom policy in Studio and perhaps title it “vGPU HDX 3D Pro” and apply the following sUgGeStEd vGPU HDX 3D Pro policy as described in this nVidia GRID forum article available at – Why not use my current HDX policy? Firstly this policy is a sUgGeStEd and should be considered as an initial base line to begin testing from and its based off real world field experience from an EMEA nVidia GRID Architecture based in the UK.
2. The following XenDesktop master class from July 2014 will provide you with a great insight into HDX 3D Pro with nVidia GRID cards. This master class is a must if your looking at deploying an HDX 3D Pro with a customers environment to enable the deliver of HDX Rich Graphics to users within LAN and WAN scenarios.

2: It is also worth reading this newly published HDX Technology white paper – if your new to delivering hosted shared desktops (XenApp 6.5, XenDesktop 7.x), VDI desktops (XenDesktop 7.x) or just a generalised refresh surrounding HDX which is built on the strength of Independent Computing Architecture (ICA) protocol –
3: What server hardware is supported for nVidia GRID K1, K2 cards – and here is where you can find the current specifications for the card themselves –
4: Review and understand the system requirements for HDX 3D Pro which is required in order to deliver the whole solution –
5: Explore, understand and review the GPU Acceleration for Windows Desktop OS’s in eDocs – and it is also worth reading through GPU Acceleration for Windows Server OS’s as well at –
6:Assuming you have not acquired a nVidia GRID K1, K2 card you should ensure that you download the latest possible and stable driver(s) – and if you require assistance also make use of nVidia’s support – I would also recommend reviewing or contacting manufacture to ensure that you have the latest and or best supported BIOS to support the whole solution end to end.
7: Download print out the following Reviewers guide to getting started – If your new to Citrix XenDesktop 7.1 and what to get started quickly follow on with this great Reviewers guide – which is referenced from –
8: Install the K1 or K2 GPU cards into your chooses server h/w platform, download the XenServer 6.2 ISO burn it to CD and also download the required hot-fixes and service packs (SP) if required to enable vGPU. Insert the CD into the host and power and install XenServer 6.2 and install the latest version of XenCenter on your desktop and connect it to your successful installed XenServer 6.2 host. Note you should always ensure when setting a PoC or pilot that you keep in-line with your organisations best practises and polices.
9: Complete hot-fixes packing process and also install the nVidia GRID Manager into Domain0 (Dom0) as instructed in the reviewers guide.
10: Create your VM in XS and remember to add the vGPU, then power on the VM to install and configure the OS -> once the installation is completed install and enable the nVidia GRID drivers – and then reboot the VM -> install Xen tools and reboot -> login install and configure as required your intensive 3D, graphical intensive applications -> join to your organisations domain and change the host name if required and reboot -> mount the XenDesktop 7.1 ISO to the VM and install the VDA (Decisions make a master images or enable R/A) and reboot -> Open Studio for XenDesktop 7.1 on your desktop and create machine catalogue and delivery group following the best practises of the reviewers guides mentioned above -> Open Citrix Receiver which can be downloaded at – and login and search for your newly created VDI desktop with vGPU and launch the resource and access one of your installed 3D or graphical intensive applications and begin testing and playing with different policies in XenDesktop 7.1 and tweaking your h/w as required to gain the maximin possible performance.
11: You can/could also test and try using – although I have not tested this utility with a VDI desktop which is vGPU ready and enabled.
