PCI Express is one of the niftiest networking solutions to come along in a long while, which is probably why the enterprise community is quickly adopting it as the de facto interconnect. There's only one small problem: It's not very good at long-distance networking.
Most PCIe solutions are limited to the 10-meter range of typical copper links. But a Norwegian company called Dolphin Interconnect Solutions says it has a line of PCIe devices optimized for fiber optic connections up to 300 meters.
The line is anchored by the DXH510 host adapter and the DXE410 PCIe expansion chassis. The 510 holds a pair of 10 Gbps external connections for connecting a single host to one or two expansion chassis. The 410 chassis, meanwhile, provides eight self-configuring PCIe slots that can accommodate either x4 or x8 designs.
The devices are part of Dolphin's wider line of enterprise cluster solutions, aimed at delivering fully integrated processor-to-processor and processor-to-I/O systems. They are due to start sampling next month, with production runs beginning by year end.
