Arista has disrupted the market for high-speed data center switches with two principal innovations. Their core innovation has been to build a better network operating system, Arista EOS® (Extensible Operating System), which they have built using innovations in core technologies. EOS is built to be open and standards-based, and its modern architecture delivers better reliability and is uniquely programmable at all system levels. EOS provides an ideal platform for customers to automate their IT workflows, while integrating with 3rd parties to achieve best-of-breed solutions in multi-vendor networks. EOS also enables customers to gain visibility across their physical and virtual networks.
The other key innovation that Arista has brought to the industry is the use of merchant silicon. Legacy approaches have relied on building teams of ASIC engineers who laboriously release proprietary ASICs that are tightly coupled to proprietary software – creating vendor lock-in, increasing product cost, and limiting customer choice. Elimination of these gratuitous interdependencies and the associated vendor lock-in that they create are the roots of the movement toward software defined networking, and the basis for the Universal Cloud Network architecture outlined in Arista’s Software Driven Cloud Networking.
In particular, Arista has championed non-blocking network performance, constant cross-sectional bandwidth availability through the use of open, standards-based network fabrics, and increases in density, power efficiency and support for new networking standards such as VXLAN without the need for wholesale replacements of network investments or commitment to a single vendor path for future purchases. Arista has built EOS so that we can support multiple families of merchant silicon – which enables rapid and comprehensive innovation to the benefit of customers across our entire data center portfolio of products, both today and in the future.
