Finally!! Someone has replied!! :-D
That’s not bad, it’s only taken 7 months to get a response despite over 1000 views! haha :-)
So, a fellow Cisco advocate! Great choice, we use Cisco servers too!
Thanks for running that benchmark and generating some results for us. I’m going to be honest, that score is on the lower side of what you should be hoping for, however it is representative of that GPUs performance and use case, which I’m sorry to say is not going to be CAD workloads. You have a good server specification with nice fast CPUs and a nice chunk of RAM, but it is really being handicapped by that GPU. Really, you should be looking at nothing less than Maxwell. The K1 was never intended for anything resource intensive. A K2 would fare a lot better for this task, but it’s older technology now, and they will soon become a bottleneck for your Hypervisor choice, as the last versions to support Kepler are XenServer 7.1 and ESXi 6.5. Drop an M60 in there and watch the performance (and user density when running CAD) change dramatically!
However, let’s see if we can bump up that score a little bit, as the tuning will be the same regardless of GPU … So, starting from the bottom:
- Ensure your UCS firmware and BIOS are fully up to date. A new version was released last month.
- Go through your BIOS settings and tune for Maximum Performance. That includes CPU, Memory and Cooling / Fan Speed. Remove all "Balanced" / "Economy" settings.
This will help you with your BIOS settings: http://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/unified-computing/whitepaper-c11-737931.html
- Hypervisor, you don’t mention what you’re using, however as you’re using Horizon, I’m pretty sure you’ll be running ESXi. Make sure this is the latest version of 6.5, nothing older! 6.5 has a lot of performance fixes over 6.0.
- Set ESXi for "High Performance".
- Install the latest NVIDIA GRID drivers for the most up to date functionality and performance.
Ok, that’s the infrastructure part covered. Nice and easy, nothing out of the ordinary there.
- RAM is fine
- GPU is a little low, I’d be looking at at least 2GB (K160Q) if not more (K180Q) for CAD. However increasing frame buffer won’t help your benchmark results.
- CPU is too low. Nothing less than 4 vCPU per VM. Maybe more when you’re running CAD workloads.
That should give you a good starting base.
Which model CPUs are you running? v2, v3 or v4?
What storage are you using for your VMs and the data?
