@ljgriz Note that SATA runs out of juice at 6gbps......

So if you run SATA drives, then it wont go higher.

I actually have two here from different vendors I tried.
One's coded for Cisco and the other's coded for Intel.

This directive was added to the boot loader config file:
hw.ix.unsupported_sfp="1"

After rebooting, when I slide either SFP module into the SFP+ cage, I get an unsupported module error from the kernel.

ix0: Unsupported SFP+ module type was detected.

I remember seeing on the Supermicro documentation that these SFP+ ports are not multimode and only support SFP+ modules.
