MSI EdgeXpert QSFP 200G Connect-X 7 Cable For DGX Spark GB10

The MSI EdgeXpert QSFP 200G ConnectX-7 stacking cable (P/N 956-C931-101) links two NVIDIA DGX Spark (GB10 Grace Blackwell) systems — such as the MSI EdgeXpert MS-C931 — over their built-in NVIDIA ConnectX-7 200GbE ports. Clustering two units combines their memory and compute to run and fine-tune AI models of up to 405 billion parameters, beyond what a single DGX Spark handles on its own.

It is a passive Direct Attach Copper (DAC) cable in the QSFP / QSFP112 form factor, sized for the short desk-side reach between two stacked units.

• Connectors: QSFP to QSFP112
• Link speed: 200 Gb/s between DGX Spark units (QSFP112 DAC rated up to 400 Gb/s, PAM-4, 112 Gb/s per lane)
• Cable type: Passive DAC (Direct Attach Copper), LSZH jacket
• Length: 400 mm (±15 mm)
• Networking: NVIDIA ConnectX-7 200GbE
• Application: DGX Spark / MSI EdgeXpert two-unit stacking
