Abstract
Methods and systems are provided for managing power allocation to a SAS target coupled with a SAS initiator through a SAS expander. The expander exchanges messages with the target to manage the power allocation to the target. The target transmits a power request message through the expander to the initiator. In some embodiments, the initiator transmits a power request received message to the expander. The expander may then transmit a power grant message to the target in response to receiving the power request received message. In other embodiments, the expander monitors the messages transmitted from the target to the initiator. The expander may then transmit a power grant message to the target in response to the expander monitoring the power request message.
