Abstract
One embodiment of the present invention provides a system for a fine-grained power management. The system receives, by a first server, a task assigned based on a global power state, wherein the first server includes one or more drives, a drive includes one or more channels, and a channel includes one or more integrated circuits. The system places an inactive drive into a power-saving mode. The system places an inactive channel of an active drive into the power-saving mode by using a power switch associated with each integrated circuit in the inactive channel. The system places an inactive integrated circuit of an active channel into the power-saving mode by using a power switch associated with the inactive integrated circuit. The system updates a data structure storing the global power state based on a current power state of the first server, the drives, the channels, and the integrated circuits.
