Server-class networking bandwidth will see a five-fold increase by 2017, exceeding 900 terabits in that year as data centers continue to increase network capacity to keep up with traffic demand, according to Crehan Research’s latest Server-class Adapter & LAN-on-Motherboard (LOM) Long-Range Forecast Report.
The transition to 10GbE is expected to account for more than 60 percent of the total bandwidth by 2014 – the year in which Crehan Research forecasts that 10GbE server-class adapter and LOM shipments should overtake GbE.
"Even without a very high attach rate of 10GbE LOMs on volume enterprise rack servers due to the current high 10GbE Modular LOM end-customer price premiums, there is enough volume on alternative server platforms such as Cloud, Blade and High-end servers to drive the 10GbE transition within a couple of years,” said Seamus Crehan, president of Crehan Research. “Furthermore, with the default inclusion of a four-port GbE Modular LOM on many Romley-based volume enterprise servers, the native Ethernet networking bandwidth (and number of ports) on these servers has been doubled at no additional price to customers," Crehan added. As a result, the Crehan report shows GbE has continued to grow while 10GbE has grown much more rapidly, leading to very healthy combined Ethernet port growth.
