You don't need it, and it's commonly preferred to _not_ use one.
Leave managing the drives to ZFS so it can impose its whole set
of features on the drives.
So if you have one in your system, don't use it. Set it to a
mode where all drives are reported individually to the system,
and _no_ kind of RAID management is performed by the controller.
The less interference, the better it is. :-)
