To prevent current inrush from exceeding power limitations of a power supply or a power domain in a multiple disk drive system the drives are powered-on in a controlled sequence. In a multi-drive blade storage subsystem, a subsystem control module inventories the locations of the hard drives in one or more drive enclosure blades and maintains information about the boundaries of one or more power domains. The subsystem control module may direct one of several drive power-on sequences, none of which allow current inrush to exceed the allowable current of each power domain.
