Specifications

Product Overview

The Arista DCS-7280SRA-48C6-R is a high-performance, cloud-grade Layer 3 switch router from the industry-leading Arista 7280R Series, designed to meet the scalability, throughput, and flexibility needs of next-generation data centers and enterprise core networks.
Equipped with 48x 10G SFP+ ports and 6x 100G QSFP28 uplinks, this switch provides high-density 10G connectivity with high-speed uplinks to ensure optimal performance in aggregation and spine deployments. The switch leverages Arista’s AlgoMatch™ engine for enhanced routing efficiency and policy control with reduced power consumption.
With a switching capacity of 2.16 Tbps and forwarding rate of 720 Mpps, along with low latency from 3.8µs, this model is purpose-built for high-demand networking environments. It also includes back-to-front airflow (ideal for hot-aisle deployments), redundant power supplies, and robust control-plane capabilities powered by a quad-core x86 CPU.
