Description

The Arista 7170-32CD is a 1RU fixed-configuration programmable data centre switch built for dense 100GbE cloud networks. It suits leaf or spine roles in scale-out leaf-spine fabrics, network overlay and virtualisation, large-scale NAT, security, telemetry and large ACL deployments.

This SKU provides 32 QSFP100 ports (40/100GbE) and 2 SFP+ ports (10GbE), with up to 6.4 Tbps throughput, up to 2.4 Bpps and latency from 800 ns. A 20 MB packet buffer supports bursty traffic. It uses front-to-rear airflow and two 1+1 redundant, hot-swap 747W AC power supplies, with a typical draw of 221 W and a maximum of 490 W. It runs Arista EOS and sits in EOS Feature License Group 2, with a minimum of EOS 4.21.3F. Optional Group 2 licences such as LIC-FIX-2-E and LIC-FIX-2-Z are ordered separately.

QSFP ports accept 40G and 100G optics and DAC/AOC cables, and support 4x10G and 25G breakout. SFP+ ports accept 10G optics and cables, plus 1GbE SX, LX and TX modules.
