Pcie lane aggregation over a high speed link

A computer network system comprising:

• a router coupled to a network source;
• a plurality of core switches coupled to the router;
• a plurality of aggregator switches coupled to each of the plurality of core switches;
• and
• a plurality of rack modules coupled to each of the plurality of aggregator switches, wherein each of the plurality of rack modules comprises:
• an I/O appliance having a downstream aggregating silicon photonics device provided on each of a plurality of optical ports numbered from 1 to N;
• and
• a plurality of server devices coupled to the I/O appliance, each of the server devices having a PCIe (Peripheral Component Interconnect Express) interface, and an upstream aggregator module coupled to the plurality of server devices and aggregating each of the PCIe interfaces.

A method of operating a computer network system having an I/O appliance, a plurality of server devices coupled to the I/O appliance, and an upstream aggregating silicon photonics device coupled to the plurality of server devices;

• the method comprising:
• receiving, by a plurality of optical ports of the I/O appliance numbered from 1 to N, a data stream;
• aggregating, by a downstream aggregating silicon photonics device of the I/O appliance provided on each of the plurality of optical ports, the data stream;
• processing, by a Peripheral Component Interconnect Express (PCIe) interface of each server device, the data stream;
• and
• aggregating, by the upstream aggregating silicon photonics device, each of the PCIe interfaces to aggregate the data stream.
