Citrix XenDesktop 7.1
Citrix XenDesktop 7.1 is now finally released and vGPU is now in the product and build in with MCS, very very cool. You can configure GPU pass-through with any GPU card or vGPU profiles with NVIDIA GRID, the brilliant thing about this its now build in to the product, you only have to choose a GPU profile and XenDesktop takes care of the High Availability with XenServer and find the resources that free and connects the GPU to the Virtual Machine. Microsoft have just released Windows 8.1 and Server 2012R2 and in this release of Citrix XenDesktop 7.1, Citrix are supporting Microsoft newest Operating System Platforms.
One of the things that have been fixed in the XenDesktop 7.1 Virtual Delivery Agent is following:
- With HDX 3D Pro enabled, the NVIDIA card might not support certain resolutions. This enhancement introduces support of up to 2560×1600 pixel resolutions.
- With HDX 3D Pro enabled, client connections to a XenDesktop 5.6 VDA do not support resolutions beyond 1900×1200 pixels. This enhancement introduces support for a wide range of additional resolution ratios, including:
- 1920×1200
- 2048×1152
- 2560×1440
- 2560×1600
What’s new in XenDesktop 7.1
- GPU — The Graphical Processing Unit (GPU) capabilities feature provides graphics virtualization, offering a superior experience for users who use graphic-intensive applications and often manipulate 3-D models. The GPU feature also can improve the graphics experience for a large number of users. Administrators can evaluate workflows for the creation of GPU-capable connections and machine catalogs created with an MCS-provisioned master image. If problems are encountered, then Administrators may need to manually create the machines.
When you install Citrix XenDesktop 7.1 on the Controller, you can now choose a GPU type and group which its getting from XenServer.
If you have NVIDIA GRID with XenServer, XenDesktop 7.1 takes care of creating a GPU type attached to the GPU group.
in above example I am choosing a vGPU type: K140Q. It have 960MB video RAM per VM)
If you have 1 GRID K1 card and choose a K140Q type, you can have maximum 16 virtual machines assigned to this card. If you have 2 GRID K1 and choose K140Q type, then you can have 32 virtual machines assigned to the GROUP K1, and XenDesktop 7.1/XenServer vGPU takes care of the HA of GPU assignment.
Look at below chart to get an understanding of which vGPU types you can choose in XenDesktop 7.1 with NVIDIA GRID K1 & K2.
Read my blogpost about vGPU profiles
The above numbers are from NVIDIA but the vGPU types Citrix have defined in XenDesktop 7.1 are following:
for NVIDIA GRID K1 vGPU options:
- GRID K100 (256B video RAM per VM)
- GRID K140Q (960MB video RAM per VM)
- Passthrough – GK107 GL GRID K1
for NVIDIA GRID K2 vGPU options:
- GRID K260Q (1920MB video RAM per VM)
- GRID K240Q (960MB video RAM per VM)
- GRID K200 (256MB video RAM per VM)
- Passthrough – GK104GL
- Windows Server 2012 R2 and Windows 8.1 support — Deliver a high-definition user experience on Windows 8.1 virtual desktops and physical machines. HDX 3D Pro has also been upgraded to support Windows 8.1.
Upgrade XenDesktop 7 components to 7.1
When you run the installer AutoSelect, the wizard checks whether certain Site components (such as the Delivery Controllers, Director, and VDAs), need to be upgraded. If you opt not to upgrade some components during this process, when you run Studio, it performs a component check and notifies you when components need to be upgraded. You cannot proceed to manage your Site until you upgrade these components.
Upgrade Site with components deployed on different machines
The following figure shows the high-level processes involved when upgrading a XenDesktop 7 to XenDesktop 7.1 in which Studio components are deployed on different machines.
Perform the upgrade procedures in the following order.
Check the licenses
Make sure that your Subscription Advantage date for licenses is no earlier than 2013.0522.
Upgrade StoreFront
If StoreFront is deployed on a separate machine, follow the steps described in Upgrade core components from eDocs
Upgrade Director
If Director is deployed on a separate machine, follow the steps described in Upgrade core components from eDocs
Upgrade Provisioning Services
If you are using Provisioning Services, follow the procedures described in Upgrading Provisioning Services from eDocs
Upgrade the Virtual Delivery Agent
For Remote PC Access deployments, Citrix recommends that you upgrade a VDA in a remote PC using a command-line method. For detailed information, see Install using the command line.
- Log on to the server using a local administrator account and run the installer by inserting the media or mounting the ISO drive for this release, and double-clickingAutoSelect.
- On the Welcome page, click Start. The wizard detects what components need to be upgraded and displays the Upgrade options page, activating the components you can upgrade.
- On the Upgrade options page, select:
- Virtual Delivery Agent for Windows Desktop OS for Desktop OS, and earlier XenDesktop versions
- Virtual Delivery Agent for Windows Server OS for Server OS
- On the Firewall page review the default ports and configure firewall rules.
- On the Summary review the prerequisites to be installed and the components to be upgraded then click Upgrade.
- On the Finish Upgrade page one of the following messages appears upon completion:
- Success — Upgrade successful appears when the upgrade completes without errors.
- Failed — The Upgrade failed appears with a list of failed components. Click Why did this fail to review what you must do to fix the problem. Other components that installed successfully are retained; you do not need to reinstall them.
- Click Finish to complete the upgrade.
Upgrade Delivery Controllers
- Upgrade half of your Site’s Delivery Controllers.
- Use the upgraded version of Studio to perform the Site upgrade as described in Upgrade core components.
- Upgrade your remaining Delivery Controllers.
Upgrade Databases using Studio
Use Studio to upgrade the Database.
Automatically upgrade Databases
- Start Studio. The wizard detects what components need to be upgraded and displays the Mandatory upgrade page.
- Select Start the Site upgrade automatically.
- At the prompt, select I am ready to upgrade.The wizard displays the upgrade progress. After the upgrade completes, the wizard performs tests. This takes several minutes.
- At the Site Upgrade Complete window, you can optionally view a data migration report and then click Finish.
- At the Upgrade successful page, click Finish upgrade and return to the Site overview.
Manually upgrade Databases
To minimize Site down time when performing a manual upgrade, it is important that the XenDesktop Administrator closely coordinates with the Database Administrator. This process requires that you run a script that temporarily disables Xendesktop Services while the manual upgrade scripts are run by the Database Administrator using a preferred tool (for example, SQL Server Management Studio). Ideally, immediately after these scripts complete, the XenDesktop Administrator should enable XenDesktop Services and complete the upgrade using Studio.
Manual upgrade requires:
- Backing up the databases
- Running the generated scripts in the following order:
- DisableServices.ps1 — PowerShell script to be run by the XenDesktop administrator on an XenDesktop Controller.
- UpgradeSiteDatabase.sql — SQL script run where the Site databases resides
- UpgradeMonitorDatabase.sql — SQL script run where the Monitor databases resides.
- UpgradeLoggingDatabase.sql — SQL script run where the Logging database resides.
Note: You should only run this script if the Logging database changes. For example, run it after applying a hotfix.
- EnableServices.ps1 — PowerShell script to be run by the XenDesktop administrator on an XenDesktop Controller.
To upgrade manually
- Start Studio. The wizard detects what components need to be upgraded and displays the Mandatory upgrade page.
- Select Manually upgrade this site.
- The wizard checks for License Server compatibility. Make sure your License Server and license files are compatible with XenDesktop 7.1. Select the confirmation check box and click Continue.
- The wizard prompts you to backup the Database. When you have done so, select the confirmation check box and click Continue.
- The wizard generates the manual upgrade scripts that you must run and displays them in a window
- The Mandatory Upgrade page changes to display a checklist of the manual upgrade steps
- Make sure you have completed the checklist tasks and click Finish upgrade and return to Common Tasks.
