GPU & AI Infrastructure — NVIDIA GPUs, HGX Systems & High-Speed Interconnects

Building an AI training cluster, GPU inference farm, or high-performance compute environment requires more than just GPUs — it requires the right interconnects, cables, and accessories to wire everything together at the speeds AI workloads demand. Resilient Tec specializes in the networking and interconnect layer of GPU infrastructure, with a catalog focused on NVIDIA/Mellanox platforms.

What's in This Collection?

GPU Compute Hardware — NVIDIA A100, H100, A30 GPUs and HGX/DGX system components (new and refurbished)
High-Speed DAC & AOC Cables — 200G QSFP56, 400G QSFP-DD, and 800G OSFP cables for GPU cluster fabric wiring
InfiniBand & NVLink Accessories — HDR and NDR InfiniBand cables and components for DGX SuperPOD and HPC clusters
Network Adapters — Mellanox/NVIDIA ConnectX NICs for GPU servers

Why Interconnects Matter in AI Clusters

In an AI training cluster, GPU-to-GPU bandwidth is as critical as compute. A bottleneck in the fabric — wrong cable length, incompatible transceiver, mismatched breakout config — can reduce training throughput across the entire cluster. Every interconnect product in this collection is:

EEPROM-coded for NVIDIA/Mellanox Spectrum and Quantum platforms — no "unsupported optics" errors
Tested for 800G OSFP, 400G QSFP-DD, and 200G QSFP56 configurations common in DGX and HGX builds
Available with same-day shipping on most in-stock SKUs — critical for keeping cluster builds on schedule
