K1 grid: NVIDIA GRID K1 Specs | TechPowerUp GPU Database

Nvidia GRID K1 in an HPE ML310e Gen8 v2

I can’t tell you how excited I am that after many years, I’ve finally gotten my hands on and purchased an Nvidia Quadro K1 GPU. This card will be used in my homelab to learn, and demo Nvidia GRID accelerated graphics on VMware Horizon View. In this post I’ll outline the details, installation, configuration, and thoughts. And of course I’ll have plenty of pictures below!

The focus will be to use this card both with vGPU, as well as 3D accelerated vSGA inside in an HPE server running ESXi 6.5 and VMware Horizon View 7.8.

Please Note: As of late (late 2020), hardware h.264 offloading no longer functions with VMware Horizon and VMware BLAST with NVidia Grid K1/K2 cards. More information can be found at https://www.stephenwagner.com/2020/10/10/nvidia-vgpu-grid-k1-k2-no-h364-session-encoding-offload/

Please Note: Some, most, or all of what I’m doing is not officially supported by Nvidia, HPE, and/or VMware. I am simply doing this to learn and demo, and there was a real possibility that it may not have worked since I’m not following the vendor HCL (Hardware Compatibility lists). If you attempt to do this, or something similar, you do so at your own risk.

For some time I’ve been trying to source either an Nvidia GRID K1/K2 or an AMD FirePro S7150 to get started with a simple homelab/demo environment. One of the reasons for the time it took was I didn’t want to spend too much on it, especially with the chances it may not even work.

Essentially, I have 3 Servers:

  1. HPE DL360p Gen8 (Dual Proc, 128GB RAM)
  2. HPE DL360p Gen8 (Dual Proc, 128GB RAM)
  3. HPE ML310e Gen8 v2 (Single Proc, 32GB RAM)

For the DL360p servers, while the servers are beefy enough, have enough power (dual redundant power supplies), and resources, unfortunately the PCIe slots are half-height. In order for me to use a dual-height card, I’d need to rig something up to have an eGPU (external GPU) outside of the server.

As for the ML310e, it’s an entry level tower server. While it does support dual-height (dual slot) PCIe cards, it only has a single 350W power supply, misses some fancy server technologies (I’ve had issues with VT-d, etc), and only a single processor. I should be able to install the card, however I’m worried about powering it (it has no 6pin PCIe power connector), and having ESXi be able to use it.

Finally, I was worried about cooling. The GRID K1 and GRID K2 are typically passively cooled and meant to be installed in to rack servers with fans running at jet engine speeds. If I used the DL360p with an external setup, this would cause issues. If I used the ML310e internally, I had significant doubts that cooling would be enough. The ML310e did have the plastic air baffles, but only had one fan for the expansion cards area, and of course not all the air would pass through the GRID K1 card.

The Purchase

Because of a limited budget, and the possibility I may not even be able to get it working, I didn’t want to spend too much. I found an eBay user local in my city who had a couple Grid K1 and Grid K2 cards, as well as a bunch of other cool stuff.

We spoke and he decided to give me a wicked deal on the Grid K1 card. I thought this was a fantastic idea as the power requirements were significantly less (more likely to work on the ML310e) on the K1 card at 130 W max power, versus the K2 card at 225 W max power.

The above chart is a capture from:
https://www.nvidia.com/content/cloud-computing/pdf/nvidia-grid-datasheet-k1-k2.pdf

We set a time and a place to meet. Preemptively I ran out to a local supply store to purchase an LP4 power adapter splitter, as well as a LP4 to 6pin PCIe power adapter. There were no available power connectors inside of the ML310e server so this was needed. I still thought the chances of this working were slim…

These are the adapters I purchased:

  • StarTech LP4 to 2x LP4 Power Y Splitter Cable M/F
  • StarTech 6in LP4 to 6 Pin PCI Express Video Card Power Cable Adapter

Preparation and Software Installation

I also decided to go ahead and download the Nvidia GRID Software Package. This includes the release notes, user guide, ESXi vib driver (includes vSGA, vGPU), as well as guest drivers for vGPU and pass through. The package also includes the GRID vGPU Manager. The driver I used was from:
https://www.nvidia.com/Download/driverResults.aspx/144909/en-us

To install, I copied over the vib file “NVIDIA-vGPU-kepler-VMware_ESXi_6.5_Host_Driver_367.130-1OEM.650.0.0.4598673.vib” to a datastore, enabled SSH, and then ran the following command to install:

esxcli software vib install -v /path/to/file/NVIDIA-vGPU-kepler-VMware_ESXi_6.5_Host_Driver_367.130-1OEM.650.0.0.4598673.vib

The command completed successfully and I shut down the host. Now I waited to meet.

We finally met and the transaction went smooth in a parking lot (people were staring at us as I handed him cash, and he handed me a big brick of something folded inside of grey static wrap). The card looked like it was in beautiful shape, and we had a good but brief chat. I’ll definitely be purchasing some more hardware from him.

Hardware Installation

Installing the card in the ML310e was difficult and took some time with care. First I had to remove the plastic air baffle. Then I had issues getting it inside of the case as the back bracket was 1cm too long to be able to put the card in. I had to finesse and slide in on and angle but finally got it installed. The back bracket (front side of case) on the other side slid in to the blue plastic case bracket. This was nice as the ML310e was designed for extremely long PCIe expansion cards and has a bracket on the front side of the case to help support and hold the card up as well.

For power I disconnected the DVD-ROM (who uses those anyways, right?), and connected the LP5 splitter and the LP5 to 6pin power adapter. I finally hooked it up to the card.

I laid the cables out nicely and then re-installed the air baffle. Everything was snug and tight.

Host Configuration

Powering on the server was a tense moment for me. A few things could have happened:

  1. Server won’t power on
  2. Server would power on but hang & report health alert
  3. Nvidia GRID card could overheat
  4. Nvidia GRID card could overheat and become damaged
  5. Nvidia GRID card could overheat and catch fire
  6. Server would boot but not recognize the card
  7. Server would boot, recognize the card, but not work
  8. Server would boot, recognize the card, and work

With great suspense, the server powered on as per normal. No errors or health alerts were presented.

I logged in to iLo on the server, and watched the server perform a BIOS POST, and start it’s boot to ESXi. Everything was looking well and normal.

After ESXi booted, and the server came online in vCenter. I went to the server and confirmed the GRID K1 was detected. I went ahead and configured 2 GPUs for vGPU, and 2 GPUs for 3D vSGA.

VM Configuration

I restarted the X.org service (required when changing the options above), and proceeded to add a vGPU to a virtual machine I already had configured and was using for VDI. You do this by adding a “Shared PCI Device”, selecting “NVIDIA GRID vGPU”, and I chose to use the highest profile available on the K1 card called “grid_k180q”.

VM Settings to add NVIDIA GRID vGPU

After adding and selecting ok, you should see a warning telling you that must allocate and reserve all resources for the virtual machine, click “ok” and continue.

Power On and Testing

I went ahead and powered on the VM. I used the vSphere VM console to install the Nvidia GRID driver package (included in the driver ZIP file downloaded earlier) on the guest. I then restarted the guest.

After restarting, I logged in via Horizon, and could instantly tell it was working. Next step was to disable the VMware vSGA Display Adapter in the “Device Manager” and restart the host again.

Upon restarting again, to see if I had full 3D acceleration, I opened DirectX diagnostics by clicking on “Start” -> “Run” -> “dxdiag”.

It worked! Now it was time to check the temperature of the card to make sure nothing was overheating. I enabled SSH on the ESXi host, logged in, and ran the “nvidia-smi” command.

“nvidia-smi” command on ESXi Host

According to this, the different GPUs ranged from 33C to 50C which was PERFECT! Further testing under stress, and I haven’t gotten a core to go above 56. The ML310e still has an option in the BIOS to increase fan speed, which I may test in the future if the temps get higher.

With “nvidia-smi” you can see the 4 GPUs, power usage, temperatures, memory usage, GPU utilization, and processes. This is the main GPU manager for the card. There are some other flags you can use for relevant information.

Final Thoughts

Overall I’m very impressed, and it’s working great. While I haven’t tested any games, it’s working perfect for videos, music, YouTube, and multi-monitor support on my 10ZiG 5948qv. I’m using 2 displays with both running at 1920×1080 for resolution.

I’m looking forward to doing some tests with this VM while continuing to use vGPU. I will also be doing some testing utilizing 3D Accelerated vSGA.

The two coolest parts of this project are:

  • 3D Acceleration and Hardware h.264 Encoding on VMware Horizon
  • Getting a GRID K1 working on an HPE ML310e Gen8 v2

Highly recommend getting a setup like this for your own homelab!

Uses and Projects

Well, I’m writing this “Uses and Projects” section after I wrote the original article (it’s now March 8th, 2020). I have to say I couldn’t be impressed more with this setup, using it as my daily driver.

Since I’ve set this up, I’ve used it remotely while on airplanes, working while travelling, even for video editing.

Some of the projects (and posts) I’ve done, can be found here:

  • VDI 3D Graphics and Game Demo with Horizon
