Description

High-performance HHHL SuperNIC designed for accelerated AI/HPC and ultra‑low‑latency fabrics. A single OSFP cage supports 800Gb/s XDR InfiniBand by default, or can be configured for 2x400GbE to fit converged data center needs. Deliver deterministic latency with advanced RDMA/RoCEv2 offloads, deep virtualization (SR‑IOV), and precise time sync. Ideal for GPU‑dense servers and storage nodes requiring extreme throughput, congestion control, and scalable fabric connectivity.

FAQs

Q: Does this adapter support both InfiniBand and Ethernet?
A: Yes. It supports 800Gb/s XDR InfiniBand by default and can be configured for 2x400GbE.

Q: What transceiver form factor is used?
A: OSFP (single-cage). Use compatible OSFP optics, DACs, or AOCs.

Q: What PCIe slot is recommended?
A: A PCIe Gen5 x16 slot is recommended to achieve full bandwidth and lowest latency.

Q: Is RoCEv2 supported for Ethernet deployments?
A: Yes. RoCEv2 and RDMA offloads are supported for low-latency, lossless Ethernet fabrics.

Q: Can this be used in GPU servers for AI workloads?
A: Yes. It is optimized for AI/HPC, enabling high-throughput, low-latency connectivity and GPUDirect-friendly operation.
