According to the Server-Class Adapter & LAN-on-Motherboard (LOM) Long-Range forecast report from Crehan Research Inc., access to multiple data centre Ethernet speeds will result in a much stronger server networking upgrade cycle than seen over the past decade. The availability of 25GbE, 50GbE and 100GbE products, together with existing 10GbE and 40GbE products, is predicted to achieve more than two-thirds of total networking ports shifting to high-speed Ethernet in a matter of three years.

"Over the past decade or so, the data centre has seen many significant changes, and it is no longer a one-size-fits-all market," said Seamus Crehan, president of Crehan Research. "Consequently, we are seeing solutions that are highly optimised for the needs of specific customer segments, whether it be a fully vertically integrated system for a converged enterprise network or a bare-bones disaggregated system for a massively scalable cloud service provider," he said. "As a result, the market is currently looking for more targeted Ethernet networking solutions."

Crehan Research Data Centre Networking Forecast January 2015

The report predicts that the many various high-speed Ethernet options will coexist for some time, each benefitting from the demands of a specific market segment. For example, 25GbE is expected to see a strong initial ramp from deployments by cloud titans such as Google and Microsoft, an area of the market where 10GbE server networking is prevalent. The forecast also stated that 10GbE should see its third, and biggest, adoption phase as the mainstream enterprise market upgrades its mostly 1GBASE-T server and server access infrastructure to 10GBASE-T. In addition, the research firm predicted that 40GbE is starting to ramp significantly, benefitting from a window of opportunity as the most attractively priced data centre Ethernet speed from a bandwidth perspective.

Crehan Research also highlighted the dramatic uptake in 40GbE data centre adoption, noting that networking bandwidth demands were so strong in some market verticals that these customers could not wait to evaluate impending 25GbE and 50GbE options.
