NVIDIA Spectrum-4 Ethernet Switches

Ethernet Switching Solutions for the Accelerated Data Center

Cloud-native, accelerated computing, and AI are the new networking frontiers, and data is the fuel that drives these workloads. AI represents a powerful growth driver that spans all industries. All workloads are becoming cloud-native; scaled out with containerized microservices that need massive bandwidth to access data and communicate across the data center. The new NVIDIA Spectrum®-4, the 5th generation of ASICs in the NVIDIA Spectrum Ethernet platform, arrives just in time to meet the needs of cloud-native, accelerated computing, and AI workloads. Spectrum accelerates workloads from core, to cloud, to edge.
