Consulting shown in Fig. 2, is the functional block diagram of SAS port monitoring system of the present invention preferred embodiment.

Described SAS port monitoring system 30 comprises monitoring modular 100, judge module 200 and control module 300.

Whether described monitoring modular 100 has data to pass through for the SAS line of monitoring each PHY chip 21 correspondences by described front-end interface 31.The SAS line of each PHY chip 21 includes a pair of transmission line (TX) and receives line (RX), is connected to described front-end interface 31.In the time having data by described transmission line or receive line, have Voltage-output, described monitoring modular 100 is by the voltage of the described transmission line of detecting and reception line, and whether can monitor the transmission line of each PHY chip 21 and receive in line has data to pass through.

Described judge module 200, for according to monitoring result, judges the duty of each PHY chip 21.In the time having data to pass through in the SAS line of described PHY chip 21 correspondences, described judge module 200 judges that the duty of this PHY chip 21 is for normal.In the time not having data to pass through in the SAS line of described PHY chip 21 correspondences, described judge module 200 judges that the duty of this PHY chip 21 is for abnormal.
