 P0 - Local SAS 1 which is far from RTM zone 3 connector
 P1 - Local SAS 2 which is near from RTM zone 3 connector
 P2 - External SAS 1
 P3 - External SAS 2
The BIOS and Linux follow the SAS port physical number to assign sequence number. For
example, BIOS and Linux will assign sequence number as following:
