Arista Networks has announced two new platforms supporting 400 Gigabit Ethernet. The 400G systems deliver the performance that hyperscale cloud networks and data centres need for the growth of applications such as AI (artificial intelligence), machine learning and IoT.

The Arista 7060X4 Series uses industry standard optics for 400G and offers the choice of two optical module form factors – OSFP and QSFP-DD. Both form factors offer a wide choice of 400G optics and cables, including optics that provide backward compatibility for 100G ports.

This gives customers flexibility in building high density leaf spine networks to support the most demanding emerging applications, including 100G connectivity to servers and 400G connectivity in the leaf-spine fabric.

Andreas Bechtolsheim, Arista chairman and chief development officer, said: “We have introduced our first 400G switching platforms delivering four times the throughput, double the price/performance and double the power efficiency of our previous 100G platforms.

“These products will address pent-up demand for more bandwidth in cloud networks, allowing cloud service providers to build much more scalable networks.”

The new platforms, which are based on the Broadcom 12.8 Tbps Tomahawk 3 silicon, support 32 400G ports in a compact 1U chassis. In addition, each 400G port can be split into four 100G ports, which supports a total of 128 100G ports in a 1U chassis. Enhancements in Arista EOS traffic management and load balancing take advantage of on-chip improvements in buffering and routing resources.

“The release of Arista’s 7060X4 Series based on our switch silicon will help accelerate cloud adoption of scale-out 400GbE networks,” said Ram Velaga, senior vice president and general manager, switch products at Broadcom. “The combined solution addresses the need for substantially higher network performance and power efficiency for the new wave of cloud workloads.”

The 7060PX4-32 is available in Q4, and the 7060DX4-32 will be available in Q1 2019. Pricing starts at under $1,800 per port of 400G, “dramatically lowering the price per gigabit”, said Arista.

The 7060X4 Series will be demonstrated at the SuperComputing 2018 conference in Dallas, Texas on 11-16 November.
