Independent B2B sourcing context
SwitchInfra organizes switches, transceivers, network adapters, and fiber or copper cabling for Ethernet, RoCE, and InfiniBand project discovery and RFQ preparation.
NVIDIA and Mellanox names describe buyer-specified platform families only and do not imply official affiliation or compatibility. Confirm the exact OPN or SKU, platform, software or firmware, topology, availability, delivery, warranty, and terms in technical review and RFQ.
Specify the network architecture, topology, switch and host-adapter identifiers, port and data rate, optics or cable reach, connector, software or firmware context, quantities, and deployment schedule.
No. Those names identify buyer-requested platform families only. Compatibility requires verification of the exact OPN or SKU, platform, software or firmware, topology, and link components.
SwitchInfra 51.2T Ethernet fabric solution is purpose-built for NVIDIA B300 GPU clusters, delivering 800G port-to-port connectivity with RoCEv2 lossless networking. The dual-plane architecture improves scalability, reliability, and GPU communication efficiency. A dedicated RDMA storage network isolates storage and compute traffic, reduces CPU overhead, and accelerates AI training. Powered by Tomahawk 5 silicon and PicOS®, the solution provides 51.2 Tbps of switching capacity per chassis with intelligent congestion control, deep buffers, and hardware-accelerated load balancing to reduce network bottlenecks in large-scale AI training deployments.


The 51.2T Ethernet fabric uses a dual-plane spine-leaf design. The compute plane carries GPU east-west communication over lossless RoCEv2, the storage plane isolates RDMA storage traffic, and the management plane automates deployment and monitoring through AmpCon-DC.
