Description

Quad-port VPI adapter delivering up to 4x 400GbE or 400Gb/s InfiniBand for AI/HPC fabrics, accelerated storage, and ultra‑low‑latency cloud. PCIe Gen5 x32 provides massive host bandwidth with advanced offloads: RDMA (RoCE v2), GPUDirect RDMA, NVMe‑oF, inline IPsec/TLS, and IEEE 1588 PTP hardware timestamping for precision timing.

Features

- Quad 400G VPI ports for extreme throughput and fabric flexibility
- PCIe Gen5 x32 host interface to sustain multi‑port 400G performance
- Advanced accelerations: RDMA, GPUDirect RDMA, NVMe‑oF
- Inline IPsec/TLS for secure, high‑throughput data in motion
- PTP hardware timestamping for precise time synchronization
- SR‑IOV and DPDK for high‑density, low‑latency virtualization

FAQs

Q: Is the card backward compatible with earlier PCIe generations?
A: Yes. It functions in PCIe Gen4/Gen3 slots at reduced aggregate bandwidth.

Q: Can I run Ethernet on some ports and InfiniBand on others?
A: Yes. VPI allows per‑port selection of Ethernet or InfiniBand (not both simultaneously on the same port).

Q: Are optics or cables included?
A: No. Transceivers and cables are sold separately.

Q: Does it support GPUDirect RDMA?
A: Yes, with supported GPUs and drivers.

Q: What offloads are available?
A: RDMA (RoCE v2/IB), NVMe‑oF, SR‑IOV, inline IPsec/TLS, and hardware timestamping.
