A storage controller has an operating system (OS) and power control firmware configured to manage use of battery power during a power outage event. The OS specifies to the power control firmware first and second sets of physical components that should be shed by power control firmware during a two-phase vault process. Upon a power failure, the power control firmware turns off power to the first set of physical components and notifies the OS of the power failure. The OS determines whether to abort or continue the vault process. If the OS aborts the vault process, the power control firmware restores power to the first set of physical components. If the OS continues the vault process, the power control firmware turns off power to the second set of physical components, the OS saves application state, and moves all data from volatile memory to persistent memory.

Maintaining data integrity through power loss with operating system control

In one or more embodiments, one or more systems, one or more methods, and/or one or more processes may determine that a platform reset signal from a processor of an information handling system has been asserted; may determine that a power conservation state from the processor was not asserted within an amount of time; may determine that an operating system restart occurred; may notify a hardware root of trust device to authenticate information handling system firmware; may assert a resume reset signal to the processor; may authenticate the information handling system firmware; may de-assert a power OK signal to the processor; may remove power from the processor; may determine that the resume reset signal to the processor is de-asserted and that the processor is out of the power conservation state; and may provide power to the processor.
