About Arista Networks

Arista Networks was founded to pioneer and deliver software-driven cloud networking solutions for large data center storage and computing environments.

Arista’s award-winning platforms, ranging in Ethernet speeds from 10 to 100 gigabits per second, redefine scalability, agility and resilience. Arista has shipped more than 10 million cloud networking ports worldwide with CloudVision and EOS, an advanced network operating system. Committed to open standards, Arista is a founding member of the 25/50GbE consortium. Arista Networks products are available worldwide directly and through partners.

Arista’s crown jewel, EOS, is the most advanced network operating system to enable open third party development. The award-winning software is built upon a stable, open source Linux core with a central state-oriented database that makes EOS inherently self-healing, in-service upgradeable and extremely robust. Arista EOS Central offers access to development tools, scripting examples, and support to deliver real-world solutions that bridge the gap between what vendors build and what users want. Arista actively shares code samples, engages in collaborative forums, and posts works in progress to get early insight into use cases.

Arista was recognized by Gartner as a "leader" in its " 2016 Magic Quadrant for Data Center Networking " based on a number of factors, including high growth, technology solutions and flexible software. The Arista team is comprised of experienced management and engineering talent from leading networking companies. Arista designs revolutionary products in California and delivers them worldwide through distribution partners, systems integrators and resellers with a strong dedication to partner and customer success.

The Arista Advantage

The world is moving to the cloud to achieve better agility and economy, following the lead of the cloud titans who have rede ned the economics of application delivery during the last decade. Arista’s innovations in cloud networking are making this possible. New modern applications such as social media and big data, new architectures such as dense server virtualization and IP Storage and the imperative of mobile access to all applications have placed enormous demands on the network infrastructure in datacenters.

  • Applications have been decomposed into multiple tiers of interoperable subsystems leveraging new standards. These applications are deployed in scalable pods or clusters that make scaling and supporting them easier.

  • Tra c patterns that once centered on the use of lightly utilized links in and out of the datacenter (north-south) for mainframe and client-server applications have been supplanted by highly distributed applications that drive heavily utilized links for server-to-server and server-to-storage (east-west) tra c within the datacenter.

  • Datacenters that once consisted of hundreds of servers are now built on a scale of more than 100,000 physical servers and more than one million virtual machines (VMs) or containers.

  • Availability requirements for the new datacenter network are also higher -- now 24x7x365 -- with no time for maintenance windows or planned downtime.

    Network architectures, and the network operating systems that make the cloud possible, need to be fundamentally di erent from the highly over-subscribed, hierarchical, multi-tiered and costly legacy solutions of the past.
