Abstract
Power consumption of a device (e.g., flash storage driver, hard drive, etc.) connected to a host computer system is managed to promote efficient power usage and improved service. Communication between a host computer system (e.g., an operating system) and a device is enabled so that the host system can ascertain a power footprint of the device. Taking the power footprint of the device into consideration, along with the power consumption of the system as a whole (e.g., including the power consumption needs of other devices), a power manager can provide a power budget to the device based upon an informed decision. This allows for improved system power management through a coordination of the device's power consumption by the host system, specifically during operation allowing device performance to be enhanced for the task at hand.
