Zusammenfassung:	The invention relates to methods and apparatus dynamic management of multiplexex PHYs in a serial attached SCSI domain. Methods and systems for automatically, dynamically reconfiguring multiplexing functions of a PHY of a SAS device in response to monitored performance of the PHY and/or in response to changes in configuration of devices in the SAS domain. A SAS device (102) such as a SAS initiator or a SAS expander in a SAS domain may monitor performance (104) of PHYs (110) of the device to detect bandwidth utilization and may reconfigure multiplexing functions (106) of a PHY to improve bandwidth utilization of the PHYs of the device. The device may also detect changes (104) in the topology of the SAS domain such as addition of new devices or removal of device and adjust multiplexing functions of its PHYs accordingly to improve performance of communications in the SAS domain.
