Description

Next-generation Ethernet adapter offering up to 400GbE over QSFP112 for dense compute, storage, and AI fabrics. With PCIe Gen5 x16 and extensive offloads (NVMe-oF/TCP, OVS, TLS/IPsec, RoCEv2), it delivers extreme throughput while reducing CPU overhead. Supports IEEE 1588v2 PTP, advanced telemetry, and breakout modes such as 4x100G where supported. Compatible with QSFP family optics and DAC/AOC matched to the selected speed.

Features

- Extreme 400GbE bandwidth for modern AI/HPC clusters
- PCIe Gen5 x16 host interface for maximal throughput
- Robust offloads for storage, networking, and security
- RoCEv2 enables ultra-low latency fabric performance
- Advanced telemetry and congestion control for stability at scale
- Flexible breakout configurations to 4x100G where supported

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.

FAQs

Q: What optical modules do I need for 400GbE?
A: Use QSFP112 optical modules or DAC/AOC rated for 400GbE. The adapter can negotiate lower speeds with appropriate modules/cables.

Q: Does the adapter support SR-IOV and RDMA?
A: Yes. It supports SR-IOV for virtualization and RoCEv2 for low-latency networking.

Q: Will it work in a PCIe Gen4 slot?
A: It can link at lower PCIe generations (e.g., Gen4) with reduced bandwidth compared to Gen5 x16.

Q: Is 4x100G breakout supported?
A: Yes, with compatible breakout cables and optics, subject to platform and firmware support.

Q: Which operating systems are supported?
A: Major Linux distributions, Windows Server, and VMware ESXi are supported. Check the vendor compatibility matrix for exact versions.
