     ami - American Megatrends Inc. MegaRAID Controllers

SYNOPSIS    [Toc]    [Back]

     ami* at pci? dev ? function ?

DESCRIPTION    [Toc]    [Back]

     The ami driver provides support for the MegaRAID  family  of
RAID controllers,
 including:

           Dell    PERC2/DC,   PERC3/DC,   PERC3/DCL,   PERC3/QC,
PERC3/SC,
           Dell PERC4/DC, PERC4/SC, PERC4/Di, PERC4/Si, and CERC
           Hewlett-Packard 438, 466, and T[567]
           LSI/AMI MegaRAID
           LSI/Symbios 523 SATA

     These controllers support RAID 0, RAID 1, RAID 5, JBOD,  and
superpositions
 of those configurations.

     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 iop(4) driver.

     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.
