MPT(4)							   BSD Kernel Interfaces Manual 						    MPT(4)

NAME

     mpt -- LSI Fusion-MPT SCSI/Fibre Channel driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device mpt

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   mpt_load="YES"

DESCRIPTION

     The mpt driver provides support for the LSI Logic Fusion-MPT family of SCSI, Fibre Channel and SAS controllers.

HARDWARE

     The following controllers are supported by the mpt driver:

     o	 LSI Logic 53c1030, LSI Logic LSI2x320-X (Single and Dual Ultra320 SCSI)
     o	 LSI Logic AS1064, LSI Logic AS1068 (SAS/SATA)
     o	 LSI Logic FC909 (1Gb/s Fibre Channel)
     o	 LSI Logic FC909A (Dual 1Gb/s Fibre Channel)
     o	 LSI Logic FC919, LSI Logic 7102XP-LC (Single 2Gb/s Fibre Channel)
     o	 LSI Logic FC929, LSI Logic FC929X, LSI Logic 7202XP-LC (Dual 2Gb/s Fibre Channel)
     o	 LSI Logic FC949X (Dual 4Gb/s Fibre Channel)
     o	 LSI Logic FC949E, LSI Logic FC949ES (Dual 4Gb/s Fibre Channel PCI-Express)

     The Ultra 320 SCSI controller chips supported by the mpt driver can be found onboard on many systems including:

     o	 Dell PowerEdge 1750 thru 2850
     o	 IBM eServer xSeries 335

     These systems also contain Integrated Raid Mirroring and Integrated Raid Mirroring Enhanced which this driver also supports.

     The SAS controller chips are also present on many new AMD/Opteron based systems, like the Sun 4100.  Note that this controller can drive both
     SAS and SATA drives or a mix of them at the same time. The Integrated Raid Mirroring available for these controllers is poorly supported at
     best.

     The Fibre Channel controller chipset are supported by a broad variety of speeds and systems.  The Apple Fibre Channel HBA is in fact the
     FC949ES card.

     This driver also supports target mode for Fibre Channel cards.  This support may be enabled by setting the desired role of the core via the
     LSI Logic firmware utility that establishes what roles the card can take on - no separate compilation is required.

HISTORY

     The mpt driver first appeared in FreeBSD 4.6.

AUTHORS

     The mpt driver was originally written for FreeBSD by Greg Ansley and marginally improved upon by Matt Jacob <mjacob@FreeBSD.org>.

     Justin Gibbs <gibbs@FreeBSD.org> and Scott Long <scottl@FreeBSD.org> have made more substantial improvements.

ATARAID(4)                                                 BSD Kernel Interfaces Manual                                                 ATARAID(4)

NAME

     ataraid -- ATA software RAID support

SYNOPSIS

     device ata
     device ataraid

DESCRIPTION

     The ataraid driver provides support for so-called software RAID (sometimes referred to as fake RAID or pseudo RAID).

     When a controller that supports software RAID is instructed to create a RAID array, its BIOS writes data structures in a specific metadata
     format to the disks.  These data structures are picked up by the ataraid driver, so that FreeBSD can work with the array.  The ataraid driver
     has to understand the specific metadata format of a controller BIOS in order to support its RAID capabilities.

     Read-only support for a metadata format means that FreeBSD can use the given RAID array for normal read/write operations.  Creation and
     rebuild of such arrays has to be done from the controller BIOS.

     Read and write support for a metadata format means that FreeBSD can use the given RAID array for normal read/write operations.  Additionally,
     the atacontrol(8) utility can be used to create, rebuild, update and fail such RAID arrays.

     The ataraid driver can read the following metadata formats:

     o   Adaptec HostRAID
     o   Highpoint V2 RocketRAID
     o   Highpoint V3 RocketRAID
     o   Intel MatrixRAID
     o   Integrated Technology Express (ITE)
     o   JMicron
     o   LSI Logic V2 MegaRAID
     o   LSI Logic V3 MegaRAID
     o   NVIDIA MediaShield
     o   Promise FastTrak
     o   Silicon Image Medley
     o   Silicon Integrated Systems (SiS)
     o   VIA Tech V-RAID
     o   FreeBSD PseudoRAID

     The ataraid driver can write the following metadata formats:

     o   Highpoint V2 RocketRAID
     o   Intel MatrixRAID
     o   JMicron
     o   Promise FastTrak
     o   Silicon Integrated Systems (SiS)
     o   VIA Tech V-RAID
     o   FreeBSD PseudoRAID

     It is also possible to use software RAID on controllers that do not have special software RAID capabilities.  See atacontrol(8) for details.

CAVEATS

     RAID5 is not supported at this time.  Code exists, but it neither uses nor maintains parity information.
