SANTA CLARA, Calif. – A consortium of companies including Arista Networks, Broadcom Corporation, Google Inc., Mellanox Technologies, Ltd., and Microsoft Corp. today announced the availability of a specification optimized to allow data center networks to run over a 25 or 50 Gigabit per second (Gbit/s) Ethernet link protocol. This new specification will enable the cost-efficient scaling of network bandwidth delivered to server and storage endpoints in next-generation cloud infrastructure, where workloads are expected to surpass the capacity of 10 or 40 Gbps Ethernet links deployed today.

The 25 Gigabit Ethernet Consortium was formed by the above leading cloud networking technology providers for the purpose of supporting an industry-standard, interoperable Ethernet specification that boosts the performance and slashes the interconnect cost per Gbps between the server Network Interface Controller (NIC) and Top-of-Rack (ToR) switch. The specification adopted by the Consortium prescribes a single-lane 25 Gbps Ethernet and dual-lane 50 Gbps Ethernet link protocol, enabling up to 2.5X higher performance per physical lane or twinax copper wire between the rack endpoint and switch compared to current 10 Gbps and 40 Gbps Ethernet links. The new specification is being made available royalty-free by the Consortium members to any data center ecosystem vendor or consumer who joins the Consortium.

By deploying 25 and 50 Gbps Ethernet in their networks, builders of mega-scale data centers such as Microsoft expect to achieve operational advantages, including reduced CapEx and OpEx. “The new Ethernet speeds proposed by the Consortium give superior flexibility in matching future workloads with network equipment and cabling, with the option to ‘scale-as-you-go,’” said Yousef Khalidi, Distinguished Engineer, Microsoft. “In essence, the specification published by the 25 Gigabit Ethernet Consortium maximizes the radix and bandwidth flexibility of the data center network while leveraging many of the same fundamental technologies and behaviors already defined by the IEEE 802.3 standard.”

The companies’ motivation for founding the Consortium is to immediately set an industry standard definition of the 25 Gbps and 50 Gbps Ethernet physical layer (PHY) and media access control layer (MAC) behavior, including virtual lane alignment, autonegotiation, and forward error correction characteristics, to enable the swift rollout of 25 Gbps and 50 Gbps Ethernet compliant implementations over the next 12 to 18 months through the participation of multiple semiconductor, networking equipment and interconnect vendors in the Consortium.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
