NAME
     mfi - LSI Logic & Dell MegaRAID SAS RAID controller

SYNOPSIS
     mfi* at pci?
     scsibus* at mfi?

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

           -   Dell PERC 5/e, PERC 5/i, PERC 6/e, PERC 6/i
           -   Intel RAID Controller SRCSAS18E, SRCSAS144E
           -   LSI Logic MegaRAID SAS 8300XLP, MegaRAID SAS 8308ELP, MegaRAID
               SAS 8344ELP, MegaRAID SAS 8408E, MegaRAID SAS 8480E, MegaRAID
               SAS 8888ELP, MegaRAID SAS 8880EM2

     These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID
     50 and RAID 60 using either SAS or SATA II drives.

     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.
