System for providing physically separated compute and I/O resources in the datacenter to enable space and power savings

摘要

An embodiment of a system and method disaggregate I/O resources from a server's compute resources, such as CPU and memory, by moving the server's local I/O devices to a remote location apart from the server's compute resources. An embodiment uses optical technology to accomplish the fast communication speeds needed between the compute resources and the remotely located I/O resources. Specifically, an embodiment uses fiber-optic cables and electrical-to-optical conversion to facilitate communication between the compute resources and the I/O resources. The compute resources and the remotely located I/O resources can be designed differently to allow conductive liquid cooling for the compute resources and air cooling for the I/O resources.

1. A system for providing physically separated compute and input/output (I/O) resources in a datacenter, the system comprising:
a compute room, the compute room not having any cold or hot aisles; a compute rack of a server infrastructure for housing one or more compute resources in the compute room of the datacenter, wherein the compute rack uses liquid cooling for the one or more compute resources, the liquid cooling includes liquid lines to and from the compute rack; an I/O room remotely and separately located from the compute room, the I/O room including an I/O cold aisle having cool air and an I/O hot aisle having hot air; an I/O rack for housing one or more I/O resources in the I/O room of the datacenter, wherein the I/O rack uses air cooling for the one or more I/O resources, the air cooling includes the cool air provided from the I/O cold aisle to the I/O rack and the hot air exhausted from the I/O rack to the I/O hot aisle; and optical cables enabling communication between the one or more compute resources and the one or more I/O resources, wherein the one or more compute resources use more power than the one or more I/O resources.
