Citrix Linux VDA now supports Ubuntu 16.04

Last year I wrote a blog on how to find out which Linux distributions are supported by VMware/Citrix, at the time I struggled to find some of the Citrix info as there wasn’t a master list in their documentation. With the recent 7.12 XenDesktop release though this changed and there’s now a nice clear list in the System Requirement Documentation (at the time of writing for 7.12), this reads: Continue reading “Citrix Linux VDA now supports Ubuntu 16.04”

NVIDIA GRID: More info on vApps and VPC/vWS Licensing

Check out Luke Wignall’s blog on NVIDIA GRID licensing and other GRID topics!

I wrote a blog on RDSH (including XenApp) licensing and the options available with NVIDIA GRID vGPU and GPU-passthrough a few weeks ago, which you can read – here (including support for multi-monitor and resolutions). Since then my colleague Luke has added some more information in a blog where he outlines various case studies including many on vApps, which is worth a read here:

Luke answers how many licenses and what type you will need for various use cases, answering questions such as: Continue reading “NVIDIA GRID: More info on vApps and VPC/vWS Licensing”

NVIDIA GRID: Citrix HDX adds support for Relative and Absolute Mouse Modes to Linux Receiver

Update: 14th September 2016 – Receiver For Windows 4.5 released today now adds support for Windows in addition to Linux!

Just a quick blog to highlight the availability on the Citrix HDX/ICA protocol of a feature enabling Relative Mouse mode. This is a particularly interesting for many NVIDIA GRID vGPU and graphical users as it enables better behavior of certain gaming like applications, particularly those favoured in federal simulations (battle and flight-simulators) e.g Bohemia Simulations VBS 2 & 3. Before on certain application without using an addition gamepad device the mouse could behave strangely ending up with the user pointing their barrel at the ground or sky.

Optimising TCP for Citrix HDX/ICA including Netscaler

Marius Sandbu – NGCA (NVIDIA GRID Community Advisor)  aka Clever Viking!

The TCP implementation within Citrix HDX/ICA protocol used by XenDesktop and XenApp and also Citrix Netscaler is pretty Vanilla to the original TCP/IP standards and definition and the out-of-the-box configuration usually does a good job on LAN. However, for WAN scenarios particularly with higher latencies and certain kinds of data (file transfers), Citrix deployments can benefit greatly from some tuning.

NVIDIA GRID: Linux Guest OS support for Linux distributions on Citrix and VMware

I was recently involved in a support inquiry where a user wanted to know if NVIDIA GRID vGPU was available on Linux VDAs with the Linux guest OS, OpenSUSE LEAP (the answer at the time of writing is that it’s NOT!). Finding the answer was a lot harder than I expected as both VMware and Citrix documentation took a bit of hunting around.

Much of the marketing around Linux VDA’s mentions support for “SUSE”, “CentOS” or other genres of Linux, such as this blog. It is important that customers check both their hypervisor and VDI solutions official support matrix as both Citrix and VMware only certify, QA and support specific versions of Linux Guest OSs (usually only enterprise supported versions).

More Lenovo Servers Support NVIDIA GPUs Including the M60

Lenovo have recently qualified and announced support for more NVIDIA GPUs for several servers including the x3650 M5 (E5-2600 v4), details can be found on Lenovo’s site, here:

Also recently listed is the x3500 M5:

This means Lenovo have worked with NVIDIA to test and certify that both parties hardware, firmware and software is fully-compatible, thermally and electrically stable. Continue reading “More Lenovo Servers Support NVIDIA GPUs Including the M60”

New Cisco Validated Design featuring UCS B200 M4 with NVIDIA GRID M6 vGPU – available now!

It’s great to see a new validated design released by Cisco in recent weeks. Particularly as this features the NVIDIA GRID M6 options for blade servers to enable virtualized GPU-accelerations (vGPU). This reference architecture joins other available for UCS but in particular features a reference blueprint for Citrix XenDesktop/XenApp 7.7 and VMware vSphere 6.0 for 5000 Seats. Key features include

  • Citrix XenDesktop/XenApp 7.7.
  • Built on Cisco UCS (including Cisco B200 M4 Blade Server) and Cisco Nexus 9000 Series
  • with NetApp AFF 8080EX
  • VMware vSphere ESXi 6.0 Update 1 Hypervisor Platform

Cisco have done a great job providing a comprehensive guide and reference for a full VDI/XenApp deployment that includes networking, storage and graphics acceleration considerations.


Cisco-NVIDIA Relationship

There are plenty of case studies, whitepapers and webinar recording covering Cisco long-investment in NVIDIA GRID and vGPU too:

NVIDIA GRID GPUs perfect for keeping up with the Raspberry Pi and the next generation of end points


Citrix have been making a fair bit of noise about their end-client (Receiver) being available and supported in-conjunction with partner ThinLinx on the Raspberry Pi, which with peripherals is proving a sub-$100 thin-client, capable of handling demanding graphics and frame rates (fps) of 30fps or more (YouTube is usually 30fps).

The Raspberry Pi and other low-cost end-points such as the Intel NUC are capable because they support hardware decode of protocols such as H.264 and JPEG used by HDX/ICA, they have SoC (system on a chip) hardware designed to handle graphics really very well.
