Hear from our experiences working with partners and customers worldwide about the top 10 keys to completing a successful VDI PoC using NVIDIA GRID vGPU technology.
2. Most Common Mistakes During POCs
Not defining PoC success criteria with stakeholders
Define measureable metrics
Use actual applications and data
Don’t use GPU-centric benchmarks to simulate multiple users
3. Most Common Mistakes During POCs
Attempt to add PoC into existing IT infrastructure
Use an isolated and controlled environment
Retain PoC environment for tuning and troubleshooting after
deployment
Setup a gateway for license server access if required
4. Most Common Mistakes During POCs
Not understanding application resource requirements
During typical user workloads, performance limiting factor is?
Application is CPU or memory-bound?
GPU frame buffer or rendering-bound?
Perfmon on existing workstations : “NVIDIA_GPU” counters
5. Most Common Mistakes During POCs
Not using all available resources of information
NVIDIA deployment guides, application sizing guides
Citrix and VMware reviewer guides and best practices
6. Most Common Mistakes During POCs
Attempting to use non GRID certified servers
There are many versions of GRID / Tesla cards
Not every card works in every server

8. Most Common Mistakes During POCs
Optimal CPUs for the workload are not used
Most CAD applications are very single threaded
Focus on higher CPU frequency, not number of cores
9. Most Common Mistakes During POCs
BIOS power profile is set incorrectly
Set power profile to “Maximum Performance”
Ensure CPUs can reach their highest clock speeds
10. Most Common Mistakes During POCs
Servers don’t have enough memory
Memory overcommit does not work with vGPU
4GB : Power User, Entry Level Engineering
8GB : Mid-range Engineering, Video
16GB : Advanced Engineering
32GB : CAD/CAM
64GB : Digital Mock Up
11. Most Common Mistakes During POCs
Insufficient storage IOPS
Workstation class users expect…
SSD performance since they use it locally as well
12. Most Common Mistakes During POCs
Inadequate network environment for VDI
Don’t use legacy network type in VM : prefer VMXNET3
Confirm network’s ability to deliver enough bandwidth
“iperf” may be used to simulate single and parallel TCP/UDP
networkd streams to confirm available bandwidth exists
13. Most Common Mistakes During POCs
Not enough vCPUs assigned to a VM
Assign at least 4 vCPU to a vGPU enabled VM
Two vCPUs for application
One vCPU for OS and system-calls
One vCPU for remoting protocol compression
14. Most Common Mistakes During POCs
Not optimizing virtual machine base image
Eliminate OS-level performance inhibitors
Citrix : “TargetOSOptimizer” tool
VMware : “VMwareOSOptimizationTool”
