High Performance Multi-function Programmable Platforms
The Arista 7170 Series are a unique family of purpose built multifunctional programmable 100GbE systems, based on the Intel Tofino family of switch chips, designed for high performance environments and to meet the needs of the largest scale data centers. The highly flexible packet processor architecture of the 7170 series, combined with the rich control plane provided by Arista EOS, offers a P4 programmable data-plane that enables innovative applications to be deployed in the network at wire-speed, consuming minimal power and space.
EOS provides a selection of forwarding profiles that address use cases for Cloud Providers, Enterprises, Service Providers and Content Delivery Network operators. The forwarding profiles, written in P4, implement advanced functionality including hypervisor offload, network address translation, server load balancing and customized application specific data plane behavior to address networking requirements that would traditionally require dedicated appliances or proprietary processing modules for routers.

7170 Series Technical Specifications and Features
The 7170 Series is available in a choice of configurations with up to 6.4Tbps throughput and 64 x QSFP100 ports. Designed to address leaf and spine roles or deployment as a centralized services node, each 7170 model is a fixed configuration system designed around a single high-performance system-on-chip packet processor. A selection of packet processor variants provide flexible choice in the number of programmable resources available to the system including the number of programmable match-action engines, amount of centralized shared buffer and size of TCAM and SRAM memory for lookup tables.
