US Patent 11971771 Peer storage device messaging for power management

Systems and methods for peer data storage device messaging over a control bus for power management are disclosed. Storage devices may include a host interface configured to connect to a host system and a control bus interface to connect to a control bus. Peer data storage devices may establish peer communication through the control bus interface, determine a power state, receive a power change indicator from a peer data storage device, and initiate a change in their power state. The peer data storage devices may manage their collective power as a power pool and increase or decrease power use without host intervention.
