Brand:

Arista

Specifications

Product Overview

The Arista DCS-7170-64C-R is a high-density, ultra-performance switch purpose-built for next-generation data center environments. Featuring 64x 100GbE QSFP28 ports, this switch delivers a massive 12.8 Tbps switching capacity and 4.8 billion packets per second (Bpps) forwarding rate — supporting extreme scale, speed, and flexibility for modern networks.
Powered by a multi-core x86 CPU and the Arista EOS operating system, this model offers programmable features, automation-ready infrastructure, and deterministic low latency starting from 800 nanoseconds. Designed with back-to-front airflow, the DCS-7170-64C-R is optimized for data centers employing cold aisle containment strategies.
