Arista Ships Smarter 400G Routers

Arista is taking the wraps off its second-generation 400G routers, with built-in security, routing, automation and telemetry for reduced capex and opex costs, the company announced today.

"The products we're introducing provide the highest density and highest performance of anything in the industry," brags Martin Hull, Arista associate vice president, systems engineering and platforms, in an interview with Light Reading. The Arista 7800R, 7500R and 7280R Series routers, with support for 100G and 400G Ethernet, are designed for the increased bandwidth needs of telcos and other service providers in the face of emerging technologies, including edge, 5G, network functions virtualization (NFV) and IoT. Rather than having to deploy separate devices for networking, security and telemetry, operators can run it all on a single device. "That simplification of their infrastructure makes them more agile on their journey," Hull says.

Arista's goal for the new product is to bring the scalability, simplicity, cost optimization and streamlined operations of so-called "cloud titans," such as Microsoft and Facebook, who are Arista's primary customer base, to telcos and other service providers.

Arista launched its 7060X4 switches in October, a relatively low density 1U product with 32 ports per system, typically deployed in the data center, Hull says. The new product, available in fixed and modular configurations, is higher density, at both 400G and 100G, with added security, routing, telemetry and automation.

The new 7800R3 Series provides 36 400G ports per line card, a fourfold increase over previous modular systems. The 7280R3 Series provides up to 48 400G ports that can be split into up to 192 100G ports, Arista says.

The availability of 400G data center switches followed the launch of Broadcom 12.8Tbit/s and 8Tbit/s Tomahawk 3 switches in mass production, Heavy Reading analyst Simon Stanley said last year. The new chips went into systems from Arista, Celestica, Delta Networks, and others. Other merchant silicon followed the Broadcom chips.

Arrcus claimed an industry first with a white box 400G switch in January.

Cisco unveiled its 400G switch in October, soon after Arista. Juniper launched 400G support in July.

About the Author(s)

Mitch Wagner

Executive Editor, Light Reading

San Diego-based Mitch Wagner is many things. As well as being "our guy" on the West Coast (of the US, not Scotland, or anywhere else with indifferent meteorological conditions), he's a husband (to his wife), dissatisfied Democrat, American (so he could be President some day), nonobservant Jew, and science fiction fan. Not necessarily in that order.

He's also one half of a special duo, along with Minnie, who is the co-habitor of the West Coast Bureau and Light Reading's primary chewer of sticks, though she is not the only one on the team who regularly munches on bark.

Wagner, whose previous positions include Editor-in-Chief at Internet Evolution and Executive Editor at InformationWeek, will be responsible for tracking and reporting on developments in Silicon Valley and other US West Coast hotspots of communications technology innovation.

Beats: Software-defined networking (SDN), network functions virtualization (NFV), IP networking, and colored foods (such as 'green rice').
