When connecting two DGX Spark units with one or two 0.5m 200G QSFP56 DAC cables, is an Ethernet cable still required?

Yes, you'll need an Ethernet cable or a Wi-Fi connection. DAC cables are dedicated to data transmission between devices, while the two DGX Spark units rely on an out-of-band management network for administrative communication. This network offers two options: a wired connection (Ethernet via RJ45 port, for better stability) or Wi-Fi (for easier use), so you can choose based on your needs.

What is the memory and storage capacity of two clustered DGX Spark systems?

Two DGX Spark systems can be clustered to provide 256GB of combined memory and up to 8TB of total storage.

What software and hardware does DGX Spark support?

NVIDIA DGX Spark includes a wide range of preinstalled tools, frameworks, models, and software for development. Users can join the NVIDIA Developer Program to access extensive software support, documentation, and support from the developer community. DGX Spark users can register for free with NVIDIA NGC™ to get additional SDKs, toolkits, trained models, workflows, and other resources.

Questions & Answers

Ask a Question

What does "NVIDIA DGX Spark Founder's Edition" mean?

The NVIDIA DGX Spark Founder's Edition (FE) system is built by NVIDIA, with a design similar to a scaled-down version of the original DGX-1 system that NVIDIA manufactured and shipped in 2016. The DGX Spark Founder's Edition will be available in limited quantities; once sold out, it will no longer be available for purchase. DGX Spark units supplied by OEM partners will feature separate physical designs created by the respective OEM partners and will be available in bulk.

DGX Spark supports the bonding for stacking/clustering of two units. What are the solutions for supporting additional stacking/clustering?

NVIDIA supports connecting two DGX Spark systems using one certified QSFP cable.

How many DAC cables are recommended for connecting two DGX Spark units?

It is recommended to configure 2 DAC cables, supporting flexible usage: you can plug in one for daily operation and keep the other as a backup, or plug in both simultaneously for connectivity. Both setups are supported, offering versatile connectivity options.

I bought four DGX Sparks and four 0.5m 200G Q56 DACs. For daily use, I connect each pair of units with either one or two DACs—both work great. The remaining DACs serve as spares for redundancy. Whether using a single DAC or two, the setup runs perfectly stable with smooth, consistent performance. If a DAC ever fails, I can swap in a replacement right away. I'm really satisfied with how reliable and hassle-free the whole setup is.

- so are you running a cluster of 4 together or 2 separate clusters of 2? By Gary Gilbert gary

I bought one DGX Spark bundle. This bundle is a smart pick—having two units plus the 0.5m 200G Q56 DAC takes the hassle out of finding the right cables—everything works together seamlessly right out of the box. The included DAC cable performs really well for linking the two: transmission stays consistent, and the error rate is really low, which makes a big difference for our data-heavy workloads. Solid, reliable, and exactly what we needed for our dual-unit setup.
