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.
