At the same time, the first-generation 100GE ports and line-card components themselves are fairly large and power-hungry, he said.
As with earlier technologies, standardization of the backplane should help 100GE move beyond proprietary designs and create a larger ecosystem of component vendors, eventually driving up production volumes and lowering costs through economies of scale, D'Ambrosia said. Power requirements also are likely to be driven down, he said.
The backplane group is also considering a new specification for a narrower cable interface, which should also help to save space in equipment designs and could lead to more flexible copper cables linking servers with data-center switches, D'Ambrosia said.
