<p><P>PROBLEM TO BE SOLVED: To provide methods and systems for managing power allocation to an SAS target (106) coupled with an SAS initiator (104) through an SAS expander (102). <P>SOLUTION: The expander exchanges messages with the target to manage the power allocation to the target. The target transmits a power request message (202) through the expander to the initiator. In some embodiments, the initiator transmits a power request received message (204) to the expander. The expander may then transmit a power grant message (210) 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 (210) to the target in response to the expander monitoring the power request message. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
