10. The most difficult to justify probably re the cost(s) but assigning a low end vGPU GRID profile or utilising the Intel Iris Pro Graphics with XenServer 7 to provide enough/suitable GPU capacity to all virtual apps & desktops (oldISH and modern) provides a much better experience so setup a PoC to see and try if for yourself and finally NVidia now supports H.264 offloading onto there GRID Cards in 7.11 🙂 – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/whats-new.html#par_anchortitle_59c9.

What’s New THAT You Probably Missed!
So firstly I thought I’d start with what consultants, IT Professionals and most importantly CTX SysAdmins been an ex-one myself may miss with the latest XenApp & XenDesktop 7.9 release and then cover the what’s new e.g most commonly known as a blog article up.
1 – Windows 10 support under the XAD 7.6 Long Term Service Release (LTSRP) – https://www.citrix.com/blogs/2016/06/13/a-sneak-peek-behind-the-scenes-of-the-long-term-service-release-ltsr/ but the detail about been compliant is avaiable at the following CTX article titled “CTX205549 XenApp and XenDesktop Servicing Options (LTSR) FAQ” – http://support.citrix.com/article/CTX205549 and then search for How do I get a Windows 10 VDA that is 7.6 LTSR compliant? on the web page. The following Citrix LTSR Assistant tool note its “Tech Preview – v1.0.0.32” but has been updated as of 10 June 2016 and can be downloaded at – http://support.citrix.com/article/CTX209577 but its NOT recommended when using with a production enviroment so against your UAT enviroment to ensure that your actual Citrix XAD PROD enviroment is XAD 7.6 LTSR compliant. For more in-depth information check out – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-6-long-term-service-release/xad-whats-new.html which provides a link to the Windows 10 statement for CTX205549.
2 – Support for Windows 10 in the HDX 3D Pro VDA
3 – Federated Authentication Service or FAS leverages a MS CA to dynamically issue certs to logon users as if they where using a smart card and extends Citrix authentication capabilities is must read for any real (CTX) SysAdmin and security experts – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-9/secure/federated-authentication-service.html.
4 – New default HDX graphics behaviour within XAD 7.9 is to support the use of Thinwire Compatible Mode or more commonly referred to as Thinwire+ and then to utilise “Use video codec for compression” when preferred e.g when playing a video which makes alot of sense to me so I am very happy to see this new default behaviours kudos to the HDX engineers that would on HDX Graphics Modes! Great job again 🙂
5 – HDX 3D Pro support for Intel CPUs with Intel Iris Pro graphics 5th & 6th Generation check out the following eDoc article for the full details – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-9/hdx/gpu-acceleration-desktop.html. For a good overview and demonstration of this new GPU support for XAD 7.9 powered by XenServer 7.0 yes that is correct XenServer 7.0 watch the following YouTube clip. Also please be sure to check out the latest XenServer 7.0 documentation at – http://docs.citrix.com/en-us/xenserver/xenserver-7-0.html there is some seriously new very cool stuff which I will cover in another up and comming Blog article time permitting between work and family life.
6 – The HTML5 Receiver 2.0 introduces a enhanced floating toolbar and you can now control its behaviour by completely hiding it or an individual icon only so check out the how-to at – http://docs.citrix.com/en-us/receiver/html5/2-0/about-this-release.html and after that it descirbes the new Client side appswitcher feature which also means CTX SysAdmins dont have to install the Client side appswitcher seperately on your VDAs.
7 – The following guides are for XAD 7.6+ and onwards although not actually classed as NEW they are often missed I find:

Introduction
The following blog article provides a basic understanding of how to deploy Skype for Business 2015 with the HDX Optimisation Pack 2.0 within a Citrix XenApp, XenDesktop environment which offloads the audio and video to the users local end-point running Citrix Receiver and the HDX RealTime Media Engine on supported Windows, Mac or Linux OSes. This offloading capability is powered by latest v2 HDX Optimisation Pack 2.0 architecture which can be found at – https://www.citrix.com/blogs/2016/01/12/citrix-and-microsoft-unveil-v2-solution-for-skype-for-business/ joint worked on between Citrix and Microsoft.

Understanding the HDX Optimisation Pack 2.0 vs. a Non-Optimised Deployment
The following is an oversimplified diagram which is also not intended to be 100% accurate but should provide you with a better understanding of the differences between an non-optimised vs. optimised delivery of a Skype4B virtual app from a Citrix environment.

Deploying the HDX Optimisation Pack 2.0 for Skype for Business 2015 for XenApp/XenDesktop
0. Initiate a video call using Skype for Business from your PC using Skype for Business as a published virtual app on its own or in a virtual desktop between yourself and another individual with Skype4B installed locally on their PC or Mac. Open task manager locally and on the XenApp server or virtual desktop and watch the CPU, memory and bandwidth consumption during your video call and remember to adjust screen size during the call between small, medium and full screen.
1. Install Skype for Business 2015 client within your virtual desktop (*server or desktop Windows OS).
2. Publish the Skype4B 2015 virtual app or the virtual desktop that contains app.
3. Connect to the virtual app or desktop and verify that you can open and login to your Skype4B and ensure that its functioning as normal obviously it’s not optimized but will still perform video/audio calls thanks to the HDX technologies.
4. Close Skype4B 2015 and now install the HDX RealTime Connector e.g HDX_RealTime_Connector_2.0_for_Skype_For_Business.msi downloaded from Citrix.com.
5. Disconnect from the virtual desktop*.
6. Close any ICA/HDX sessions and close Citrix Receiver
7 Next install the HDX RealTime media engine HDX_RealTime_MediaEngine_2.0_for_Windows.msi downloaded from Citrix.com.
8. Start Citrix Receiver and reconnect to your published virtual Skype4B app or virtual desktop with Skype for Business 2015 installed and you should see the HDX RealTime Connector stating “Optimised.
9. Re-initiate your video call to the same user as in step 1 above and you’ll notice the difference immediately as the video will be crisp and sharp and again open task manager and repeat the same process and you’ll see the CPU, memory and bandwidth are low on the back-end but locally on your end-point the CPU, Memory and bandwidth increases to medium as the audio and video is now been processed locally on your end-point thanks to the RTME.
Deploying the HDX Optimization Pack 2.1 for Skype4B 2016
Follow the all the steps above BUT for use with the Skype for Business 2016 you need to use the “Click-to-Run” installer and adjust the configuration.xml file for the installation to use “current” switch for the default installation behavior as Office 365 ProPlus default installation behaviour is to use “Deferred for Office 365 ProPlus. To learn how-to reconfigure the XML file in greater detail please refer to – https://technet.microsoft.com/en-us/library/jj219426.aspx for help.
Example of an HDX Offloaded Skype4B 2015 Video Call
The following picture depicts a Skype for Business 2015 video call HDX Offloaded using the HDX Optimization Pack 2.x.n between two Windows 10 virtual desktops hosted in different locations in the EU delivered to myself and a Citrite colleague in different locations within London. I myself was at partners customer event in the City using public Wi-fi that 200+ other people were connected to and using, he was at home in SW London connected to the internet over his home internet connection.
Microsoft on the Optimization Pack v2 Architecture
I’d suggest watching the following broadcast on YouTube entitled “SfB Video Broadcast: Ep 9. VDI” from the Skype for Business team providing a Microsoft perspective on the offloading capabilities for Skype4B with the Citrix Optimisation Pack 2.0. As a final thought discovery more about Skype4B at there YouTube channel which is accessiable at https://www.youtube.com/channel/UCfL-WUXlvFjLsUs4UCpPrsA.

Example of an Offloaded Skype for Business 2015 Published Citrix Virtual Desktop
The below is an example of the HDX Optimization Pack 2.0 implemented with Skype for Business 2015 client using and the latest Citrix Receiver and HDX RealTime media engine on my end-point which is a Dell Latitude E6420 running Windows 8.1. My initial test results within my IaaS home lab have been very good and I’m currently doing more testing with a few colleagues and will update this blog update as when/how time permitting with the feedback and results.
An Introduction & System Requirements (Basic’s)
The Citrix HDX RealTime Optimization Pack consists of client and server component’s and requires the following system requirements between Citrix
Receiver for Windows 4.x; Receiver for Mac 12.x; Receiver for Linux 13.x; Skype for Business 2015 Server, Business Online or Lync 2013 Server; XenDesktop 7, 7.5, 7.6 Feature Pack 1, Feature Pack 2, and Feature Pack 3. XenDesktop 7.7; ◦XenApp 6.0, 6.5, 6.5 Feature Pack 1, and 6.5 Feature Pack 2 and Feature Pack 3 , XenApp 7.5, 7.6 Feature Pack 1, Feature Pack 2, and Feature Pack 3, XenApp 7.7 with a full detailed list and overview available at – http://docs.citrix.com/en-us/hdx-optimization/2-0/hdx-realtime-optimization-pack-system-requirements.html.
Why Use The Citrix HDX RealTime Optimization Pack for Lync Performance Comparison
Client Side
The Citrix HDX RealTime Media Engine is a component that integrates within the Citrix Receiver thus providing a wide range of support device types (Windows, Mac and Linux) and offloading capabilities thus improving the UX for end-users while also improving bandwidth consumption and the density of XenApp (RDS) workloads.
Server Side
The Citrix HDX RealTime Connector (RTC) is installed alongside the Microsoft Skype for Business within a virtual desktop which allows for communication (signalling) through an Citrix ICA virtual channel between the virtual desktop and the users end-point running Citrix Receiver (RTME).
If you have any issues POST your deployment initially first verify that the RealTime Connector connectivity status which should state Connected indicating that there is a connection over the ICA virtual channel and that both client and server side components match.
