The PNY NJAAKK-N911 is a 40cm QSFP112 400G passive direct-attach copper cable for connecting NVIDIA DGX Spark systems, suited to users who need a short, high-bandwidth interconnect between nearby systems.
Recommended For
- DGX Spark owners building a two-node setup for distributed inference or fine-tuning; NVIDIA’s setup guide uses a QSFP cable for the direct connection.
- AI developers testing multi-node workloads, such as model parallelism and inter-node communication, who want to connect nearby DGX Spark systems without adding a switch for a two-system setup.
- Workgroups with two compatible DGX Spark systems placed close together, where a short direct-attach cable helps keep the interconnect compact and avoids excess cable slack.
- DGX Spark users who need an NVIDIA-listed cable for a direct QSFP connection and are setting up the connection themselves using NVIDIA’s networking instructions.
