Lee Bushen, Solutions Architect at NVIDIA discusses Virtual GPU deployment. In this presentation we cover some of the common mistakes that people make when sizing their vGPU-enabled desktops. We also cover some recommended starting points and some tools to help you get the right vGPU Profile. We'll finish by talking about how you can demonstrate to others how much better the density and user experience is with vGPU-enabled VDI desktops.

• Useful Tools for sizing
• Convincing the boss
Considerations for Virtual GPU deployments

3. TESTING DENSITY
Common Mistakes
Using low-end GPU profiles
for higher density
16 x 1GB
Profiles
16GB
=

4. TESTING DENSITY
Common Mistakes
Mapping GPU Cores to Users
Each user gets
ALL the cores
for their own
time slice

5. TESTING DENSITY
Common Mistakes
Too much density
on a single GPU
24 x 2GB VMs

6. TESTING DENSITY
What Load testing tools test
Factors to Consider
What the user wants

7. TESTING DENSITY
Common Mistakes
Using the wrong
benchmarking tools

8. TESTING DENSITY
Common Mistakes
Not taking account
of future user
requirements
Ai Applications
High Resolution – Multi-monitor
Video/Conferencing

9. TESTING DENSITY
Common Mistakes
Incorrect configuration
of remoting protocols
FPS H.264 YUV 4:2:0

10. TESTING DENSITY
Common Mistakes
Underpowered Endpoints

11. TESTING DENSITY
• Test with real workloads and users
• Best way to assess experience (smoothness, responsiveness, colour
accuracy)
• Use GPU Profiling to assess correct GPU and Profile (e.g. GPU Profiler)
• Avoid GPU Benchmarking tools (e.g. Unigine, Furmark, Games)
• Designed to test a WHOLE GPU, not a shared system
• Disable FRL and Vsync as a last resort
• Be careful with artificial VDI server load testing applications (e.g. Login VSI)
• Tests experience in the DC, not at the endpoint
• Not designed for graphical workloads
• Have some validity as a background server load

Considerations for Virtual GPU deployments

13. RECOMMENDED START POINT
• Windows Server 2016
• 8 x Virtual CPUs
• 16GB RAM
• 25-30 users
• Tesla M10 using GRID vGPU w/8GB Framebuffer profile (M10-8A)
• or Tesla T4 w/8GB Framebuffer profile (T4-8A)
• 4 x RDSH/Horizon Apps VMs per physical host (assuming 1 x M10 or 2 x T4s)
• Real-world Application workloads
• Real Users rather than simulations
RDSH Server Configuration

14. RECOMMENDED START POINT
• Windows 10
• 4 x Virtual CPUs
• 8GB RAM
• Tesla M10 or T4 using GRID vGPU w/1GB Framebuffer
(M10-1B or T4-1B profiles)
• Up to 96 users/server (3 x M10 or 6 x T4)
• Real-world Application workloads
• Real Users rather than simulations
VDI Configuration (per desktop)

20. CONVINCING THE BOSS
Use reduced CPU utilization
to prove lower HW costs:
33% more user/server
Increased Density (1/2)
Run CPU vs. CPU+GPU tests
in-VM to show lower
Utilization
Example averages:
CPU 27%
CPU+GPU 16%

21. CONVINCING THE BOSS
Better User Experience (2/2)
Demo applications that are important to the future of your business
