Those two (thanks to Luca) can get you most of the way there, but to
really hit the target you need dedicated kit like Endace (and a few
others) make. They basically do what was represented in the CCC slides
somebody else posted (FPGA with own logic), but on a PCIe card.

Once you've got the ethernet -> interface problem addressed, you need to
examine bottlenecks in interface->bus and particularly bus->disk.
