These controllers support RAID 0, RAID 1, RAID 5, JBOD,
and superpositions of those configurations.
.Pp
Some cards support both I2O and a so-called `Mass Storage' mode
of operation.
This driver only supports the `Mass Storage' mode; I2O mode is supported
by the
.Xr iop 4
driver.
.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.
