By 2013, half of all servers could include 10GE interfaces, rising to 80 percent in 2015, Bechtolsheim predicted. That’s about when Intel’s 22-nm server processors based on its Haswell design will emerge, starting a shift to 40GE on servers.
The good news is large-scale data centers are creating a robust growth market for such systems. Bechtolsheim showed market research figures estimating the data center switch business alone will rise from $4-5 billion in 2010 to $15 billion in 2015.
“This is basically tripling in five years--one of the few IT markets growing at this rate and it’s driven by the shifts from 1 to 10 and 40GE,” he said.
