Description

Dual‑port 100GbE PCIe 4.0 adapter designed for dense, virtualized, and storage‑heavy data centers. QSFP56 cages enable 100G deployments with broad cable/optic options, while RoCE v2 RDMA, SR‑IOV, and accelerated switching datapaths reduce latency and CPU overhead. Ideal for NVMe‑oF, scale‑out databases, and high‑performance cloud fabrics.

Features

- Dual 100GbE ports for high aggregate throughput and redundancy
- PCIe 4.0 x16 host interface for maximum bandwidth to the CPU/memory subsystem
- RoCE v2 RDMA and NVMe‑oF for ultra‑low latency storage and messaging
- Hardware‑accelerated virtual switching to boost VM/container networking
- PTP hardware timestamping for precise time synchronization across the fabric

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.
