Managing Link Speed

The Managing Link Speed feature lets you 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. Instead, the
firmware uses the common maximum link speed among all the phys.
Perform the following steps to change the link speed:
1. In the Controller Settings screen, press Next.
The second Controller Settings screen appears.
2. Press Manage Link Speed.
The Manage Link Speed dialog appears.
