Consortium says new specs for 25 Gbit/s and 50 Gbit/s are more cost effective than current 10 Gbit/s links.

New 25-Gig Ethernet Spec Targets Data Center

Rapid expansion of cloud services is driving development of a new Ethernet spec by a fresh consortium that includes powerhouse companies such as Google and Microsoft.

Drawing from the Institute of Electrical and Electronics Engineers Inc. (IEEE) 's 100-Gigabit Ethernet specification, the new 25 Gigabit Ethernet Consortium intends to boost the performance of data center networks. (See 25-GigE Consortium Devises Data Center Standard.)

Designed to connect servers and switches inside the data center, the new consortium's spec sets up a single-lane 25 Gbit/s and dual-lane 50 Gbit/s that are essentially fractional pieces of the IEEE's four-lane 100 Gbit/s standard, says Rochan Sankar, product marketing director, Infrastructure and Networking Group, Broadcom Corp. (Nasdaq: BRCM), which is part of the 25 Gigabit Ethernet Consortium. The new specifications are available royalty-free to any data center vendors or consumers who join.

The current process is very similar to the way 40 Gbit/s can be broken into 10 Gbit/s links, Sankar says. The result is a more cost-effective approach.

According to this report in Lightwave magazine, Microsoft Corp. (Nasdaq: MSFT) tried and failed to generate enough interest within the IEEE to launch a 25 Gbit/s spec study group. But Sankar tells us there is widespread interest within the data center ecosystem:

"Over past months, a number of companies in the data center ecosystem, including [equipment] vendors and the data center operators themselves, have recognized that this is a potential optimization point for performance and specifically performance per unit cost in the access layer of their networks, meaning the interface layer that goes between the server and the top-of-rack switch."

The IEEE is considering a study group on 25-Gig, he adds, but in the meantime, the rapid expansion of cloud services, both in type and volume, is creating a greater sense of urgency within the data center world.

"We saw a focused market need and a chance to bring this to market swiftly, with the opportunity to define a standard that fell logically out of how 100-Gig links were defined out of the IEEE," Sankar says. If the IEEE does launch a 25-Gig study group, the consortium's work could feed into that group's work.

The other consortium members, in addition to Broadcom, Microsoft, and Google (Nasdaq: GOOG), are Arista Networks Inc. and Mellanox Technologies Ltd. (Nasdaq: MLNX).

@DOShea, great point!  It is not an open checkbook, it will definitely have to deliver results and produce value soon or I suspect it will lose its representative power; and groups will splinter and go their own way.

More proof that more companies are willing to work around the standards process if it moves too slow. The vote not pursue a 25G standard in the IEEE reportedly was very close, so some level of need is obvious.

Re: 25-Gig Ethernet Spec Targets Data Center
Carol, sounds like a smart move.  By focusing on a high volume users and the growing demand on the data centers enables them to "solve" some of the data center problems - which are growing. 

I wonder if the IoT might not be another market, with its potential?
