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.

Re: 25-Gig Ethernet Spec Targets Data Center
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?
