Abstract: The present disclosure generally relates to a method for intelligent device initiated SAS Phy PM. Using device internal phy characteristics and future phy usage queue, the device determines optimal SAS Phy PM usage based on a predetermined configuration preference of power versus performance. The device achieves optimal SAS Phy PM Usage by implementing a state machine to manage phy PM states and transitions between the PM states. The device state machine includes capabilities to proactively initiate transitions to partial or slumber PM states, start early wake-up from partial or slumber PM states to mask the associated latency impacts of exiting partial or slumber PM states, and selectively reject host requests to enter a partial or slumber PM state.
