Description

The Arista 7170-64C is a 2RU programmable data centre switch with 64 QSFP100 ports and 2 SFP+ ports. It suits dense 100GbE spine and leaf designs in cloud data centres, 25/50GbE storage and compute aggregation, and programmable use cases such as network services offload, tunnel termination, large-scale NAT, custom flexible routing, flow telemetry and network security.

This SKU delivers 12.8 Tbps of throughput and a forwarding rate of up to 4.8 Bpps, with latency from 800 ns and 22 MB of packet buffer. It has front-to-rear airflow and 2 x hot-swap AC power supplies in a 1+1 redundant configuration, plus four hot-swappable N+1 fans. Each QSFP port can run at 100GbE, 40GbE, 4x10GbE, 4x25GbE or 2x50GbE, with up to 256 x 25GbE or 258 x 10GbE ports available through breakouts. It runs Arista EOS and sits in EOS Feature License Group 3.

The QSFP ports accept 40G and 100G optics and cables including SR4, XSR4, SWDM4, LR4, CWDM4, PSM4, ERL4, AOC and CR4, as well as QSFP-to-4xSFP+ and QSFP-to-SFP25 breakouts. The SFP+ ports accept 10G optics and DACs and 1GbE SX, LX and TX modules. Minimum EOS is 4.20.5F.
