Arista Networks has announced the Arista 7360X Series, a “radically new and disruptive” platform that “doubles system density while reducing power consumption and cost”. By doubling the network diameter, customers can address the demand for higher bandwidth with reduced leaf-spine tiers while lowering both capex and opex, promises the vendor.

The offering addresses the needs of hyperscale industry players looking for designs that work towards Open Compute Project (OCP) aims, which Facebook and others support.

Cloud providers, said Arista, now have the ability to migrate to higher performance 100G or 400G while leveraging Arista’s EOS (Extensible Operating System) for “single image consistency” across the network. The 7368X4 Series promotes the concept of an open platform, providing choice, scale, customisation and efficiency savings that simplify cloud network designs, Arista said.

Arista and Facebook engineering teams collaborated in the development of the system, enabling full manageability via FBOSS (Facebook Open Switching Software), controlling power and thermal efficiency along with the control plane.

“The Arista solution has helped Facebook to gain significant improvements in power and space efficiency, reducing the number of switch chips in the network stack and allowing power to be freed up for compute resources,” said Najam Ahmad, vice president of network engineering for Facebook.

“Having both an internally developed Minipack and the Arista solution allows Facebook to remain multi-sourced, with an option to run Arista EOS or FBOSS on both, where either system can be deployed in multiple tiers of networks.”

The new platform is a compact, four rack unit design and all active components are removable. It delivers a 50% improvement in density compared to traditional modular systems with a 60% reduction in power at under 10 watts per 100G port.

Standards-based, the system comes with support for 100G QSFP and 400G OSFP or QSFP-DD optics and cables. Arista EOS delivers the traffic management, automation and telemetry features needed to build and maintain modern cloud networks.

“The 7368X4 Series is a first in the networking industry. The product involved close collaboration by two talented engineering teams, resulting in a better outcome than each team designing in their own silo,” said Anshul Sadana, chief operating officer for Arista Networks.

The product is shipping now in volume with 100G interfaces. Price per 100G port is under $600.
