400G Leaf and Spine solutions for Enterprise, Cloud, SP and I/O intensive environments offering high Performance and low power

The Arista 7050X4 are members of the Arista 7050X series and key components of the Arista portfolio of data center switches. Businesses are embracing digital technologies at a much faster pace than ever before due to the shift in collaborating using online conferencing tools. Most Enterprise companies are offering more products and services online, analyzing data to gain deeper insights and embracing upcoming technologies like AI/ML to improve overall productivity. The key to these innovations being made possible is because of investments in state of the art data centers, where data is stored, processed and analyzed globally.

The adoption of next generation PCIe Gen4 based high performance compute using virtualization and containers with increasingly higher network bandwidth is accelerating the need for higher density switching in both the leaf and spine tiers of modern Enterprise networks. The Arista 7050X4 Series high performance flexible data center switches are loaded with features for wire speed L2 and L3, combine extensive automation with programmability, low latency and offer multiple generations of consistency for software driven cloud networking.
