    I don't know if it's true for the R730xd, but Dell will equip your R720xd with an LSI-branded HBA for the internal slots.  It's not on their web configurator, you have to ask your salesperson directly.  I've also bought LSI external HBA's from Dell.

    Regards,

There may be hope here, but Dell likes HW-RAID, which we generally frown up on in the illumos & ZFS communities.  The H330 looks like an LSI 3008 with "skinny" firmware on it, and the H730 looks like an LSI 3108 with "skinny" firmware on it.  Generally speaking, both of those controllers are HW-RAID.  The H330 (like its predecessor the H310) can do passthrough/raw-disk, but I believe it will be driven by the "mr_sas" driver, which has not had a lot of performance work done upon it.  Oooh, I do see, however, that the H730 now has raw-disk mode, unlike its predecessor the H710.  Still, same warning about the mr_sas driver, however.
