Abstract: A Cloud Service Provider reconfigures a memory subsystem during routine operation, while minimizing the amount of time a server is not online. Server downtime is reduced by offloading reconfiguration of system memory to the operating system with platform assistance. The operating system enumerates potential memory configurations of the memory subsystem with associated performance characteristics in an abstracted manner and performs reconfiguration of the memory subsystem without a cold reset. When reconfiguration of the memory subsystem is deemed necessary by the operating system, the operating system examines the enumerated memory subsystem configurations provided by system firmware. After selecting the memory subsystem configuration, the operating system initiates a reconfiguration process. The reconfiguration process saves any existing memory context to an auxiliary device, requests system firmware to perform the memory subsystem reconfiguration, and restores the existing memory context from the auxiliary device after the memory subsystem reconfiguration has been completed.
