For Fibre Channel, the link speed can be set to the highest speed supported by the blade containing
the ports, or a supported lower speed. Available link speeds for Xgig Fibre Channel are 1.0625
Gbps, 2.1250 Gbps, 4.2500 Gbps, or 8.5000 Gbps. For example, the Xgig 2 Gigabit
Multi-Function Blade ports can be set to
not supported. The link speed for Xgig5000 16G FC is 14.0250 Gbps and cannot be changed.
The link speed is fixed at

For 6G SAS/SATA blades and systems, the link speed can be set to the highest rate supported by
the blade containing the ports, a supported lower rate, or one of the
SAS/SATA Wide-Port/4x Blade, the 6G SAS/SATA Narrow blade, and the LX and LXP fixed-port

These blades and systems also have an auto-detect option, which will automatically detect the link
