400G

If you listen to vendor roadmaps and conference keynotes, you’d think anything below 400G belongs in a museum. But step into real networks in 2026 — service providers, regional ISPs, enterprise data centers, hybrid-cloud edges — and a very different reality emerges.

100G is not dead. In fact, for many operators, it’s still the smartest speed they can deploy.

The Arista DCS-7280CR3-32P4-M is a high-performance switch designed specifically for the demands of modern data centers and very large enterprise networks. Part of Arista's R3 series, this model offers a blend of advanced features and cutting-edge performance, making it a compelling choice for organizations aiming to optimize their network infrastructure. It’s also an ideal entry point into 400G ports for those needing to eliminate bottlenecks within a network.
