Description

Dual-port 200GbE PCIe 5.0 adapter with QSFP112 cages for ultra‑low latency networking in AI/ML, HPC, and high‑throughput storage fabrics. Supports advanced offloads including RoCEv2, GPUDirect RDMA, SR‑IOV, and NVMe‑oF/TCP for maximum efficiency and reduced CPU overhead. Backward compatible with lower link rates using supported QSFP-class optics and DAC/AOC cables.

Features

- High-throughput, low-latency connectivity for AI/ML and HPC workloads
- Future-ready QSFP112 ports with flexible speed downshifts
- Advanced offloads reduce CPU utilization and increase performance
- Accurate time synchronization with IEEE 1588v2 PTP/SyncE
- Scalable virtualization via SR-IOV and overlay offloads

FAQs

Q: Can these QSFP112 ports use 100G optics or DACs?
A: Yes. With supported modules/cables the ports can operate at lower link rates such as 100G or 200G.

Q: Does this adapter require a PCIe Gen5 slot?
A: It is optimized for PCIe Gen5 x16 but will operate in Gen4/Gen3 slots at proportionally lower bandwidth.

Q: Is RoCEv2 supported for low-latency clustering?
A: Yes, it supports RDMA over Converged Ethernet (RoCEv2) for low‑latency, high‑throughput fabrics.

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

Q: What media types are supported?
A: QSFP-class DAC/AOC cables and QSFP112-compatible optical transceivers; actual link rates depend on the module used.
