Abstract
A management controller includes a microcontroller and a managed system interface for coupling the management controller to a managed system. The managed system includes a central processing unit (CPU) and a system memory comprised of non-volatile dual in-line memory module (NVDIMM). The management controller is coupled to a management network by an out-of-band interface. The management controller provides a remote management user interface that includes a selectable out-of-band NVDIMM save element. The management controller may establish a connection with an operating system agent and control the agent to perform operations including accessing a memory map to identify an NVDIMM, configuring the NVDIMM in an asynchronous DRAM refresh mode, and triggering an NVDIMM save before toggling CPU reset.
