7050X3 Series - Arista Networks


Industry-Leading Performance, Power-Efficiency, and High Availability

Highly dynamic cloud and enterprise 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 networks. The Arista 7050X3 are members of the Arista 7050X Series and key components of the Arista portfolio of data center switches. The Arista 7050X Series are purpose-built data center switches in compact and energy efficient form factors with wire speed layer 2 and layer 3 features combined with low latency and advanced EOS features for software-defined cloud networking.

Combined with Arista EOS, the 7050X3 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.


7050X3 Series - Arista Networks


The 7050X3 supports a flexible combination of speeds including 10G, 25G, 40G, and 100G in compact form factors that allow customers to design networks to accommodate the myriad different applications and east-west traffic patterns found in modern data centers whilst providing investment protection.
