mfi(4) are RAIDs, not HBAs.  We do not recommend RAIDs with TrueNAS due 
to problems with hot-plug, disk identification, etc. and so have limited 
experience with them.  But I know some of LSI RAIDs can be reflashed 
into equivalent HBAs, so if they share the hardware, I can speculate 
that they may share some issues.
