4.8.6 Managing Link Speed The Managing Link Speed feature allows you to change the link speed between the
controller and an expander or between the controller and a drive that is directly
connected to the controller.
All phys in a SAS port can have different link speeds or can have the same link speed.
You can select a link speed setting. However, if phys in a SAS port have different link
speed settings and if a phy is connected to a drive or an expander, the firmware
overrides the link speed setting you have selected and instead uses the common
maximum link speed among all the phys.
