A management controller can dynamically manage the firmware update of a storage node in a server system. For example, an administrative device can determine the up-to-date firmware version for a storage device or a memory device associated with storage device controller, such as a SAS expander. The administrative device can send the updated firmware image to a management controller. The firmware image is a bit-by-bit replication of the updated firmware. The management controller can send the updated firmware image to storage device controller. The storage device controller can determine whether the updated firmware image is for the storage device or for the memory device associated with the storage device controller. Upon determining, updating the firmware image in the designated device can be performed. The success log and failure log can be reported to the management controller.
