AMI(4)                    OpenBSD Programmer's Manual                   AMI(4)

NAME
     ami - American Megatrends Inc. MegaRAID Controllers

SYNOPSIS
     ami* at pci? dev ? function ?
     scsibus* at ami?

DESCRIPTION
     The ami driver provides support for the MegaRAID family of RAID con-
     trollers, including:

           Dell PERC2/DC, PERC3/DC, PERC3/QC, PERC3/SC, PERC4/DC, PERC4/SC,
           Dell 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 superposi-
     tions of those configurations.

     Some cards support both I2O and a so-called `Mass Storage' mode of opera-
     tion.  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.
