Description

Dual‑port 400G HHHL SuperNIC for next‑gen Ethernet or InfiniBand fabrics. Two QSFP112 cages deliver 2x400GbE by default, with support for high‑speed InfiniBand at 400Gb/s for converged environments. Built for AI/HPC clusters and latency‑sensitive workloads, it provides rich RDMA/RoCEv2 offloads, SR‑IOV scalability, and precise timing. Ideal for spine/leaf server connectivity, GPU nodes, and NVMe‑over‑Fabrics deployments.

Features

2x400G ports for maximum server NIC density
- Flexible Ethernet/InfiniBand operation
- Advanced RDMA/RoCEv2 offloads for ultra‑low latency
- PCIe Gen5 x16 bandwidth to the host
- PTP timing for deterministic performance
- Designed for AI/HPC and high‑performance storage fabrics
