@6:50 you can also use driverctl to early bind PCIe cards to vfio drivers so you don't have to blacklist. One benefit is you can have identical cards and pass one through but let the other be used by the host OS for example. There are other benefits to using the vfio drivers as well.

Very cool! If you guys are going to show performance metrics, maybe have a baseline reference point (e.g. "we ran the same command on a single RTX 4090 and it was able to run X hashes per second"). It'll help make the metrics much more substantive. Otherwise, very cool build! Hope the client is happy with it.

Going back to when Resizable BAR was introduced, games didn't get faster until they were either updated or built with it in mind. Its been part of the PCI spec for years, but vendors didn't support it for a while.

For reference, that's at least the 3'd generation of the same TYPE of GPU server from Supermicro. The first generation has gotten pretty cheap - but it's DDR3 and uses Intel E5 first generation 2xxx or 4xxx CPUs as I recall. I'm a bit shocked you didn't go with a Supermicro mass storage solution, like their 6049 series machines, for consistancy. I've always found the 45 drives machines overpriced for what they offer, though the DO have some longevity on the core design (that is an older iteration of a BackBlaze design, but BackBlaze went with commercial designs instead of designing their own once Dell and Supermicro etc. started building high-density storage servers).

Proxmox is the way. Good to see it used.

awesome project! congrats, I was struggling with the same box a year ago. For future convenience and scalability, you might consider adding each GPU in a named resource. so you can easily migrate like: host1-gpu1 to host2-gpu1

love all your video this was brilliant

Cool stuff. Enjoyed it.

Now imagine running that GPU server with 4090 cards instead of A6000. Half again or a bit more the power draw, but on Hashcat at least 60% faster (that many more cores AND a slightly higher peak clock rate).

What was the actual settings used in the system that allowed GPU passthrough? Did you install as EXT4, XFS, ZFS? I've tried blacklisting the drivers with consumer cards but the passthrough has never worked correctly. The furthest I could get was the guest seeing the GPU and installing the drivers but CUDA was completely inaccessible or would crash the guest.

Just curious why would you go with a single root system when you are already installing 2 cpu's?

We are running these with 4070's and only one cpu so just wondering if you know something I dont :)

@JimmyLiu-SMC

The single root architecture is ideal for applications that reside on a single CPU but require access to multiple GPUs. A single root system dedicates one of the CPUs (out of two) to manage all communications with the GPUs. This results in using a maximum of 10 GPUs in a single server. A single root system is tailored for deep learning applications where most of the computation takes place on the GPU. Advantages of a Single Root configuration: - A single CPU has access to up to 10 GPUs. Applications that need direct access to all of the GPUs will benefit from this configuration. Applications - When peer-to-peer communication (GPU to GPU) performance is not critical. Supermicro has the AS-4125GS-TNRT (direct-connect GPU), AS-4125Gs-TNRT1 (Single-root), AS-4125GS-TNRT2 (Dual-root).

sounds like y'all might need three phase power 440v/208vac lol

Yes, MORE please :-) This was pure nerd porn!

This is a very sweet setup, however not at all a new idea. As my former profession was IT forensics - before I switched to IT security - I have been working with similar systems called "Octagraph" from a German company called "MH Systems" and apart from the GPU power had even more features such as forensic bridges mounted right there in the same box at the front, etc. So, more than 10 years ago there already was a more complete product, obviously with a lot less compute power due to the technology jump from back then.

BF hashes are pointless nowadays what with rainbow tables being available but what you should have done with that available power was assist by creating additional ones.

How did you think 8 GPU's could run on a single 20 amp circuit?

y eso va a estar en vena dentro de poco xD y la IA lo va a hacer tambien.

Using multiple power sockets, but presumably on the same phase? Like Ghostbusters, remember to never let the streams touch. Modern systems work fine, most of the time, with power from multiple phases, but in a fault condition you will be potentially getting a shock much greater than 110volts. With 240v in UK data centers each rack tends to operate on a single phase, a fault across two phases could give you a shock of, potentially, 415volts.

Would love to know ballpark price range of the servers. Great Video
