From the "adios 1GbE" files:

10 Gigabit Ethernet (10 GbE) has been available for some time, but is is only now that it is really hitting full stride.  According to a new report from market research firm Dell'Oro Group, for the second quarter of 2008 10GbE switch revenues exceeded $600 million.

Over 250,000 10GbE switch ports were shipped in the quarter which is also an important milestone.

I've written before about the challenges of 10GbE deployment. Often it's a cost issue - though 10GbE prices are falling. Then there was once the question of demand. Reality is that with the increasing demands placed on networks - principally by video - 10GbE is something that many (if not most) enterprise networks actually need.

Considering that 40 GbE/100GbE is years away from being a switch interconnect speed, I'd suspect that 10GbE port shipments and revenues will continue to rise for the foreseeable future.
