Arista

Specifications

Product Overview

The Arista DCS-7280CR-48-F is a top-tier switch from the 7280CR Series, purpose-built for modern data centers, high-frequency trading environments, and cloud-scale deployments. It features 48x 100G QSFP100 ports and 8x 40G QSFP+ uplinks, delivering high-density Ethernet connectivity with maximum performance.
With a total switching capacity of 10.24 Tbps and a forwarding rate of 5.76 billion packets per second (Bpps), this switch is ideal for ultra-demanding workloads, including AI/ML clusters, real-time analytics, and large-scale cloud routing. The front-to-rear airflow cooling design aligns with efficient data center cooling architectures, while the ultra-deep packet buffer of 32GB ensures smooth traffic management during congestion.
