Abstract: Described are methods for configuring computing system for and computing systems for PCIe communication between remote computing assets. The system uses a fabric interface device configured to receive multi-lane serial PCIe data from functional elements of a computing asset through a multi-lane PCIe bus, and to transparently extend the multi-lane PCIe bus by converting the multi-lane PCIe data into a retimed parallel version of the PCIe multi-lane data to be sent on bidirectional data communication paths. The fabric interface device is also configured so that the multi-lane PCIe bus can have a first number of lanes and the bidirectional data communication paths can have a different second number of lanes.

Abstract: A server rack has server sleds, each including a motherboard upon which is mounted: a memory module, a cache, at least one CPU connected to the cache, a memory controller connected to the cache and the memory module, an I/O hub, and a fabric interface (FIC) having a memory bridge and optical transceivers, where this memory bridge is connected to the I/O hub through this motherboard. The rack also has a memory sled disaggregated from the server sleds and that includes: a motherboard upon which is mounted: memory modules and a FIC having a memory bridge, a memory controller and optical transceivers, wherein this memory controller is connected to these memory modules through this motherboard, and wherein this memory bridge connects the memory controller to the optical transceivers. The rack has a photonic cross-connect switch interconnected by optical fiber cables to the optical transceivers of the server and memory sleds.
