@ljgriz Note that SATA runs out of juice at 6gbps...... So if you run SATA drives, then it wont go higher.

@lnguyen 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.
