True. The ServeRAID controllers are not (yet?) supported in 4.

I am running 4.9 on IBM x300, x305, and x335 (sorry, no 2U models).
The x335 has a built-in (motherboard) LSI RAID chip (53C1020) that is
supported by the FreeBSD mpt driver. RAID 1 mirroring has worked well,
though I have yet to attempt to monitor the controller from the OS (if
that is even possible).
