The world is moving to the cloud to achieve better agility and economy, following the lead of the cloud titans who have redefined 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.





Arista has disrupted the market for high-speed datacenter switches with two principal innovation.

  • Their core innovation has been to build a better network operating system, Arista EOS® (Extensible Operating System), which they have built from the ground up using innovations in core. 
    - EOS is built to be open and standards based.
    - Better reliability and is uniquely programmable at all system levels
    - Improved visibility, faster problem isolation and correction, and greater visibility of network performance over time across the physical and virtual networks

  • The other key innovation that Arista has brought to the industry is their use of merchant silicon.

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.

At the core of Arista's platform is the Extensible Operating System (EOS™), a ground-breaking network operating system with single-image consistency across hardware platforms, and modern core architecture enabling in-service upgrades and application extensibility.




Cloud Network Design Choices

SplineTM Layer2 / MLAG Layer3 / ECMP L2 over Layer 3 VXLAN
Spline_Design Layer2_MLAG_Design Layer3_ECMP_Design Layer3_VXLAN_Design
Server Scale: 100 to 2,000 100 to 10,000 100 to 100,000 + 100 to 100,000 +

The Arista Spline architecture attaches hosts directly to a pair of switches connected in an MLAG. This architecture can scale to more than 2000 hosts connected in a non-blocking manner. This large single tier enables densely deployed applications such as: IP and Ethernet storage, next generation file systems, distributed compute, and virtualization.

The L2LS network design is a two-tier architecture comprising of two spine switches and one or more Top-of-Rack (ToR) leaf switches. Leaf switches provide connectivity to storage, compute, service, and data center edge network elements. Leaf switches may be deployed by themselves or in a pairs for high availability. Spine switches aggregate and provide a fast backbone for the leaf switches

The L3LS network design is a two-tier architecture comprising of 2-128 spine switches and one or more Top-of-Rack (ToR) leaf switches. Leaf switches provide connectivity to storage, compute, service, and data center edge network elements. Leaf switches may be deployed by themselves or in a pairs for high availability. Spine switches aggregate and provide a fast backbone for the leaf switches.

Leveraging the same two-tier architecture of the L3LS design, the Arista Networks L3LS-V Solution also incorporates Virtual eXtensible Local Area Network (VXLAN), an open IETF specification designed to standardize an overlay encapsulation protocol, capable of relaying Layer 2 traffic over IP networks.
