Product Overview

The Arista DCS-7280SR3-48YC8 series provides a balanced blend of 25 GbE access density and 100 GbE uplink capacity, engineered for modern cloud, enterprise and data-centre fabrics. These switches support mixed-speed environments while delivering Arista’s EOS flexibility, making them suitable for both leaf and aggregation layers in scalable networks.

Ideal deployment/environment: Dense server racks, hyperconverged clusters or storage-heavy environments using 25 GbE/10 GbE server links with 100 GbE uplinks. Well suited as leaf or ToR switches in leaf-spine fabrics, giving flexible port speeds, high throughput and full-featured EOS routing/overlay capabilities without overprovisioning.
