Guide price: Price range: £2,146.83 through £14,896.40 Ex. VAT

Product Overview

The Arista DCS-7170 series (DCS-7170-64C) is a high-density, programmable data-centre switch family engineered for modern cloud, HPC and enterprise fabrics. With massive port density, high throughput and a fully programmable data plane, the 7170 series supports large-scale leaf or spine deployments with mixed-speed breakout and advanced EOS functionality.

Ideal deployment/environment: The DCS-7170-64C series fits well into large spine or leaf layers in cloud, hyperscale and enterprise data centres. The model family also suits HPC and AI/ML clusters that rely on dense 100 GbE connectivity and predictable low-latency forwarding. It is a strong choice for environments expanding east-west traffic, scaling multi-tenant workloads or standardising on EOS for automation and consistent operations.

Key Features

  • 64 × QSFP100 ports (each supporting 100 GbE, 40 GbE, or breakup into 50/25/10 GbE via breakout cables)
  • Up to 12.8 Tb/s switching capacity and up to 4.8 billion pps forwarding rate
  • Very low latency, from 800 ns port-to-port in wire-speed forwarding
  • 22 MB shared packet buffer to absorb bursts and enable lossless or burst-tolerant traffic patterns
  • Full Layer-2 / Layer-3 feature set under Arista EOS — VLAN, MLAG, ECMP/UCMP, overlay (VXLAN), ACL/QoS, full IPv4/IPv6 routing, large-scale filtering and programmable pipeline options.
  • High resiliency hardware: redundant hot-swappable PSUs, N+1 hot-swap fans, and selectable front-to-rear or rear-to-front airflow to match rack cooling requirements.
