Power management method for storage system with sleep command
A recently granted patent (Publication Number: US11966596B2) discloses a method for power management in a storage system connected to a server host. The method involves transitioning the storage system from a normal mode to a power-saving mode in response to a sleep command from the server host. This transition includes steps such as the expander outputting a predetermined register value to the processing unit before operating in the power-saving state and sending an interrupt signal. The processing unit then controls the power supply to output standby electricity, enabling the system to operate in the power-saving mode efficiently. Additionally, the method includes provisions for powering off a hard disk drive (HDD) and controlling it to operate in a power-saving manner based on received signals.
Furthermore, the patent details the involvement of a power controller, a timer in the expander, and the support for SAS protocols in the expander. The method also covers the process of transitioning back to the normal mode from the power-saving mode in response to an awakening command from the server host. This transition involves the expander and processing unit coordinating to ensure the power supply outputs operation electricity within a predefined range. The method also includes steps for controlling the HDD to operate in the normal state and enabling communication through SAS channels. Overall, the patent outlines a comprehensive method for efficient power management in a storage system, ensuring optimal performance while minimizing power consumption based on specific commands from the server host.
