Hi,
I have a 'possibility'. IF your CD/DVD are not plugged into SATA ports, do so.
Get them off this controller. SAS will try to accommodate SATA but, depending
on the order of detection, it will 'step down' in speed.
Next, try putting all the SAS drives (do you have any?), on a separate
controller line.
If you have only SATA drives, put the SATA III, followed by SATA II, (any SATA
I ?) on the chain as detected. I believe as SAS encounters devices, it will
allow transfers at the highest speed it encounters and step down as it goes.
This is all off the top of my head not having read SAS spec in a while and only
having SAS and M.2 drives now.

When I installed the server I had to enable mrsas in device.hints for
better results:
hw.mfi.mrsas_enable="1"
Any ideas why could the devices be detected as 150MB/s transfers only?
