Description

High‑density dual‑port 100GbE adapter leveraging PCIe 4.0 bandwidth for demanding cloud, virtualization, and storage fabrics. QSFP56 cages provide flexible 100G connectivity; RoCE v2, SR‑IOV, and advanced offloads reduce jitter and CPU utilization under heavy east‑west traffic. Ideal for spine/leaf hosts, NVMe‑oF targets, and latency‑sensitive workloads.

Features

- Two 100GbE ports for throughput scaling and link redundancy
- PCIe 4.0 x16 interface to eliminate host‑side bottlenecks
- RoCE v2 RDMA and NVMe‑oF acceleration for storage and HPC
- SR‑IOV and tunneling offloads to optimize virtualized workloads
- Time‑sensitive performance with PTP hardware timestamping
