Description

Single-port 400GbE PCIe 5.0 network adapter built on QSFP112 for maximum throughput in data center, AI/ML, and HPC deployments. Delivers advanced acceleration with RoCEv2, GPUDirect RDMA, SR‑IOV, and NVMe‑oF/TCP to minimize latency and CPU load. Supports lower-rate operation and breakout modes where enabled by firmware and optics.

Features

- 400G line-rate performance for next-gen fabrics
- Flexible media and speed options via QSFP112
- Reduced latency and CPU overhead with advanced offloads
- Precision timing for time-sensitive applications
- Scales virtualization with SR-IOV and overlay offloads

FAQs

Q: Is QSFP112 backward compatible with earlier QSFP optics?
A: QSFP112 uses the QSFP form factor and can interoperate at supported lower speeds with compatible modules/cables.

Q: Does it support SR-IOV for virtualization?
A: Yes, SR‑IOV is supported for high VM/VF density and performance isolation.

Q: Can I use DAC or AOC cables?
A: Yes, QSFP-class DAC and AOC cables are supported; link speed depends on cable capability and configuration.

Q: Is GPUDirect RDMA available for GPU clusters?
A: Yes, with supported GPUs and drivers it enables direct GPU-to-NIC data paths.
