Arista 7050QX Series Network Switch

The Arista 7050 Series are the benchmark for performance, scale and power efficiency in fixed 10G data center switches. Increased adoption of 10G servers is accelerating the need for flexible, dense 10GbE/40GbE solutions. The Arista 7050X Series extends the industry leading 7050 Series with increased performance, scalability, density and features designed for software defined networking.

The Arista 7050QX series offer the same wire-speed low latency and high performance switching capabilities common across the entire 7050X family. The 7050X series are a range of compact 1RU 40GbE and 10GbE scalable, multilayer switches powered by Arista EOS, the worlds most advanced network operating system.

Developing Scale-Out Networks

Scale out network designs allow solutions to start small and expand over time; simple highly scalable two-tier network designs are built with MLAG, ECMP and VXLAN technologies. The Arista 7050QX series provide the ideal platform to develop a high performance data center with a pay-as-you-grow approach.

Datacenter Network Switch

Regardless of the underpinning technology, data center networks should be developed in as few tiers as possible, maximizing performance, simplicity and determinism, while reducing capital expenses and TCO. Industry standard requirements necessitate a 2 tier leaf/spine or a single tier Spline approach.

Incorporating 32 40GbE or 96 10GbE & 8 40GbE interfaces into a single wire speed 1RU platform the 7050QX switches enable the creation of dense 2 tier designs that incorporate open standards, programmability, monitoring and visibility tools.
Datacenter Switch

The Arista Universal Network Architecture is optimized for all
application types ranging from large cloud to enterprise deployments

Arista EOS

Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency.
