+.El
+.Pp
+These controllers support RAID 0, RAID 1, RAID 5, JBOD,
+and superpositions of those configurations.
+.Pp
+Although the controllers are actual RAID controllers,
+the driver makes them look just like SCSI controllers.
+All RAID configuration is done through the controllers' BIOSes.
+.Pp
+Monitoring status for the volume and drives in it is done through the
+.Xr bioctl 8
+utility;
+the current status is provided by the
+.Xr sysctl 8
+variable
+.Va hw.sensors .
