Arista 7170 Series Switches (Used & Refurbished)
The Arista 7170 Series delivers high-performance, fully programmable data center switching with dense 100GbE ports and flexible 10/25/50/100GbE breakout options. BrightStar Systems supplies fully tested, used and refurbished 7170 switches backed by our 1-Year In-House Warranty, helping you build or expand leaf-spine fabrics and high-performance edge networks at a fraction of new hardware cost.
With P4-programmable pipelines, Arista EOS, and support for advanced telemetry and traffic engineering profiles, the 7170 family is ideal for cloud data centers, high-frequency trading, content networks, and service provider environments that need both performance and flexibility.
Arista 7170 Series Overview
The 7170 Series is built around a programmable packet processor with a flexible pipeline that can be reprofiled using EOS and P4 to support different use cases. Instead of deploying separate appliances for functions like large-scale tunneling, advanced traffic monitoring, or custom filtering, many of these capabilities can be integrated directly into the 7170 leaf or spine tiers.
Key features of the Arista 7170 Series include:
High-density 100GbE switching with QSFP100 interfaces and flexible 10/25/50/100GbE breakouts (model-dependent)
Programmable data plane using EOS profiles and P4 for custom parsing, lookups, and traffic handling
Wire-speed Layer 2/Layer 3 forwarding with advanced routing, VXLAN, and EVPN support
Shared packet buffer architecture designed for modern east-west data center traffic
Compact 1RU and 2RU fixed systems with redundant power and fan modules
If you need deep-buffered leaf/spine platforms with massive routing scale and VOQ, you may also consider pairing the 7170 with Arista 7280 Series in the same fabric.
