1. A method for managing storage-system power consumption, the method comprising: monitoring, by a first device, conditions on a first communication link between the first device and a second device; receiving, by the first device, information about conditions on a second communication link between the second device and a third device; determining, by the first device, whether the conditions on both the first communication link and the second communication link together warrant one of powering down and powering up the second device; generating, by the first device, a power-down command and transmitting the power-down command from the first device to the second device in the event the conditions warrant powering down the second device; returning, by the first device in response to requests received to access the second device while the second device is powered down, a status indicator indicating that the second device is one of busy and unavailable; and generating, by the first device, a power-up command and transmitting the power-up command from the first device to the second device in the event the conditions warrant powering up the second device.
