1. An information handling system comprising:
a processor;
a data processing unit communicatively coupled to the processor;
a logic device communicatively coupled to the processor and configured to, responsive to a shutdown event associated with the information handling system, cause a power system of the information handling system to maintain delivery of electrical energy to the data processing unit until receiving a command to cause withdrawal of the electrical energy to the data processing unit; and
a management controller communicatively coupled to the processor, the data processing unit, and the logic device, and configured for out-of-band management of the information handling system, the management controller further configured to, responsive to the shutdown event:
cause a host operating system executing on the processor to gracefully shutdown;
cause a data processing unit operating system executing on the data processing unit to gracefully shutdown; and
responsive to receiving an indication that the data processing unit operating system has gracefully shutdown, communicate the command to the logic device to cause withdrawal of the electrical energy to the data processing unit.
