PCIE lane aggregation over a high speed link

摘要

A computer network system configured with disaggregated inputs/outputs. This system can be configured in a leaf-spine architecture and can include 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. The plurality of rack modules can each include an I/O appliance with a downstream aggregator module, a plurality of server devices each with PCIe interfaces, and an upstream aggregator module that aggregates each of the PCIe interfaces. A high-speed link can be configured between the downstream and upstream aggregator modules via aggregation of many serial lanes to provide reliable high speed bit stream transport over long distances, which allows for better utilization of resources and scalability of memory capacity independent of the server count.
