Brand:

Arista

Specifications

Product Overview

The Arista DCS-7170-32C-R is a highly programmable, high-density 32-port 100GbE switch built for advanced data center and cloud infrastructure. Designed with rear-to-front (back-to-front) airflow, this switch supports optimal cooling for environments where airflow direction matters.
Offering 32x 100G QSFP28 ports and 2x 10G SFP+ uplinks, the DCS-7170-32C-R delivers a switching capacity of 6.4 Tbps and a forwarding rate of up to 2.4 Bpps, enabling low-latency, high-speed packet handling even under full load. The integrated multi-core x86 processor enhances programmability, automation, and telemetry support via Arista's Extensible Operating System (EOS).
With ultra-low latency starting from 800 nanoseconds, this switch is ideal for environments that demand consistent speed and reliability, such as high-performance computing (HPC), financial services, cloud-scale networking, and spine-leaf data center designs.
