Industry leading flexibility, programmability and performance
Highly dynamic cloud data center networks continue to expand bringing with them ever increasing bandwidth demands, accelerating the need for dense 25 and 100 Gigabit Ethernet switching in both leaf and spine tiers of modern networks. The Arista 7160 Series are purpose built fixed configuration 10/25GbE and 100GbE systems with wire speed layer 2 and layer 3 features, built for the highest performance environments, and the largest scale data centers. They combine scalable L2 and L3 resources and high density with a highly programmable and customizable switch architecture.
The 7160 can be deployed in a wide range of open networking solutions including large scale layer 2 and layer 3 cloud designs, overlay networks, virtualized or traditional enterprise data center networks.
25/100GbE and 10/40GbE Leaf and Spine solutions for cloud scale and open networking
The Arista 7160 series are purpose-built 10/25GbE and 100GbE data center switches in compact and energy efficient form factors with wirespeed layer 2 and layer 3 features. They combine scalable L2 and L3 resources with an adaptable forwarding engine and a highly programmable and customizable switch architecture that supports multiple overlay technologies and advanced encapsulations. Simple software updates allow reconfiguration of packet parsing, lookups, traffic scheduling, packet modification and traffic monitoring without re-engineering of the switch.
25GbE interfaces with SFP and 100GbE with QSFP on the 7160 Series enables flexible choices of port speed providing unparalleled flexibility and the ability to seamlessly transition data centers to the next generation of Ethernet performance. The 7160 Series provide industry leading power efficiency with airflow choices for back to front, or front to back. Combined with Arista EOS the 7160 Series delivers advanced features for cloud, big data, virtualized and traditional designs.
