mpt -- LSI Fusion-MPT SCSI/Fibre Channel driver
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
The mpt driver provides support for the LSI Logic Fusion-MPT family of
SCSI, Fibre Channel and SAS controllers.
This tunable specifies whether MSI will be used or not, provided
the controller supports it. By default, the driver will use MSI
for SAS adapters.
The following controllers are supported by the mpt driver:
* LSI Logic 53c1030, LSI Logic LSI2x320-X (Single and Dual Ultra320
* LSI Logic AS1064, LSI Logic AS1068 (SAS/SATA)
* LSI Logic FC909 (1Gb/s Fibre Channel)
* LSI Logic FC909A (Dual 1Gb/s Fibre Channel)
* LSI Logic FC919, LSI Logic 7102XP-LC (Single 2Gb/s Fibre Channel)
* LSI Logic FC929, LSI Logic FC929X, LSI Logic 7202XP-LC (Dual 2Gb/s
* LSI Logic FC949X (Dual 4Gb/s Fibre Channel)
* LSI Logic FC949E, LSI Logic FC949ES (Dual 4Gb/s Fibre Channel
The Ultra 320 SCSI controller chips supported by the mpt driver can be
found onboard on many systems including:
* Dell PowerEdge 1750 thru 2850
* IBM eServer xSeries 335
These systems also contain Integrated RAID Mirroring and Integrated RAID
Mirroring Enhanced which this driver also supports.
The 53c1030 is also available in VMware products.
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
This driver also supports target mode for Fibre Channel cards. This sup-
port 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.

The mpt driver first appeared in FreeBSD 4.6.
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.
