mrsas seems to be better maintained than mfi and I have had cards that
didnt work on RELENG12 via the mfi driver but did via mrsas[1]. You dont
need mfip as drives show up as /dev/da* and smartctl works with the
corresponding /dev/pass# device files. You can also use storcli (also in
the ports) to put it in jbod mode if you dont like megacli
eg
storcli /c0 show all
storcli /c0 show help
storcli /c0 set jbod=on (enable jbod mode for drives)
storcli /c0/e252/s0 set jbod (sets a disk into jbod mode)
I am using the mrsas driver in jbod mode on the 9272 controller for ZFS
and its nice and zippy and (so far) quite reliable.
# storcli /c0 show all
