Description

The Arista 7170 is a 1RU fixed-configuration programmable data centre switch built for dense 100GbE leaf or spine switching in cloud and large-scale data centres. It also suits programmable use cases such as network overlay and virtualisation, flexible routing and segmentation, network security, large-scale NAT, application telemetry and large-scale ACLs.

This -M-F configuration provides 32 QSFP100 ports (40/100GbE) and 2 SFP+ ports, with up to 6.4 Tbps throughput, up to 2.4 Bpps and latency from 800 ns. It pairs expanded memory options with a 30 GB SSD alongside 30 GB of flash, 16 GB of system memory (32 GB optional) and a 20 MB packet buffer. Breakout supports up to 128 x 10/25GbE or 64 x 50GbE. Airflow is front-to-rear, with two hot-swap AC power supplies in a 1+1 arrangement and four hot-swap fans (N+1). Typical draw is 221 W and maximum draw is 490 W.

The switch runs Arista EOS (minimum release 4.21.0F) and sits in EOS Feature License Group 2. Optional licences such as LIC-FIX-2-E, LIC-FIX-2-V, LIC-FIX-2-V2, LIC-FIX-2-Z and LIC-FIX-2-FLX-L are ordered separately. The 40G and 100G QSFP ports accept a wide range of SR4, LR4, CWDM4, AOC and CR4 options, and the SFP+ ports cover 10GBASE and 1GbE optics.
