Abstract
A method is provided for a SAS (Serial Attached SCSI (Small Computer System Interface)) expander to manage power consumption of a wide port that includes multiple expander phys each operable in at least three power conditions. The method includes monitoring number of AIP primitives for the wide port over time, changing at least one expander phy to a lower power condition when the number of AIP primitives total less than a first threshold over a first period of time, and changing at least one expander phy to a higher power condition when the number of AIP primitives total more than a second threshold over a second period of time.
