SAS CONTROLLER, A PHY CONFIGURING METHOD, AND A PHY RECONFIGURING METHOD CAPABLE OF PREVENTING PORT COLLISION

摘要

PURPOSE: An SAS controller, a PHY configuring method, and a PHY reconfiguring method are provided to stably maintain PHY configuration information within an SAS controller when a connected SAS device is rebooted or reset.;CONSTITUTION: A non-volatile memory(412) is connected to a processor(410) and stores port and PHY configuration information. PHYs(304-314) are connected to the processor and an SAS(Serial Attached Small Computer System Interface) device. A computer-executable program code stores the PHY configuration information in a memory. The computer-executable program code reconfigures the PHY based on PHY configuration information.;COPYRIGHT KIPO 2012
