Choosing a 400G/800G Ethernet switch requires more than comparing port speeds. From switching fabric capacity and buffer design to RoCEv2 support and scalable architecture, this guide outlines the key factors for AI and modern data center networks.

The NVIDIA Vera Rubin platform is a new computing platform for next-generation AI. Through the co-design of GPUs, CPUs, interconnects, and networks, it achieves high performance, low cost, and system-level security, supporting large-scale AI models and multi-agent applications.

CPO switches shorten the electrical signal path, reduce power consumption, and decrease the number of pluggable modules by co-packaging optical modules with switch chips, while improving link reliability. This breaks through the bottlenecks of traditional switch architecture in terms of transmission performance and energy consumption, and provides a technical path for future high-bandwidth computing.
