US 2018/0322076 A1 · METHOD TO TRIGGER NVDIMM SAVE FROM REMOTE MANAGEMENT INTERFACE

Abstract

A management controller includes a microcontroller and a managed system interface for coupling the management controller to a managed system that includes a central processing unit (CPU) and a system memory, accessible to the CPU, including a non-volatile dual in-line memory module (NVDIMM). The management controller may further include an out-of-band interface configured to couple the management controller to a management network. The management controller may include management controller instructions for providing a remote management user interface, including a selectable COB NVDIMM save element. The management controller may perform operations that include establishing a connection with an operating system (OS) agent and controlling the OS agent to perform OS agent operations. The OA agent operations may include accessing a memory map to identify an NVDIMM, configuring the NVDIMM in an asynchronous DRAM refresh (ADR) mode, and triggering an NVDIMM save, e.g., via IPMI command, before toggling CPU reset.
