39.Dt MPT 4
40.Os
41.Sh NAME
42.Nm mpt
43.Nd LSI Fusion-MPT SCSI/Fibre Channel driver
44.Sh SYNOPSIS
45To compile this driver into the kernel,
46place the following lines in your
47kernel configuration file:
48.Bd -ragged -offset indent
49.Cd "device scbus"
50.Cd "device mpt"
51.Ed
52.Pp
53Alternatively, to load the driver as a
54module at boot time, place the following line in
55.Xr loader.conf 5 :
56.Bd -literal -offset indent
57mpt_load="YES"
58.Ed
59.Sh DESCRIPTION
60The
61.Nm
62driver provides support
63for the LSI Logic Fusion-MPT family of
64.Tn SCSI ,
65.Tn Fibre Channel
66and
67.Tn SAS
68controllers.
69.Sh LOADER TUNABLES
70.Bl -tag -width indent
71.It Va hw.mpt.msi.enable
72This tunable specifies whether MSI will be used or not, provided the
73controller supports it.
74By default, the driver will use MSI for SAS adapters.
75.El
76.Sh HARDWARE
77The following controllers are supported by the
78.Nm
79driver:
80.Pp
81.Bl -bullet -compact
82.It
83LSI Logic 53c1030,
84LSI Logic LSI2x320-X
85(Single and Dual Ultra320
86.Tn SCSI )
87.It
88LSI Logic AS1064,
89LSI Logic AS1068
90.Pq Tn SAS/SATA
91.It
92LSI Logic FC909
93(1Gb/s
94.Tn Fibre Channel )
95.It
96LSI Logic FC909A
97(Dual 1Gb/s
98.Tn Fibre Channel )
99.It
100LSI Logic FC919,
101LSI Logic 7102XP-LC
102(Single 2Gb/s
103.Tn Fibre Channel )
104.It
105LSI Logic FC929,
106LSI Logic FC929X,
107LSI Logic 7202XP-LC
108(Dual 2Gb/s
109.Tn Fibre Channel )
110.It
111LSI Logic FC949X
112(Dual 4Gb/s
113.Tn Fibre Channel )
114.It
115LSI Logic FC949E,
116LSI Logic FC949ES
117(Dual 4Gb/s
118.Tn Fibre Channel PCI-Express)
119.El
120.Pp
121The
122.Tn Ultra 320 SCSI
123controller chips supported by the
124.Nm
125driver can be found onboard on many systems including:
126.Pp
127.Bl -bullet -compact
128.It
129Dell PowerEdge 1750 thru 2850
130.It
131IBM eServer xSeries 335
132.El
133.Pp
134These systems also contain Integrated RAID Mirroring and Integrated
135RAID Mirroring Enhanced which this driver also supports.
136.Pp
137The 53c1030 is also available in
138.Tn VMware
139products.
140.Pp
141The
142.Tn SAS
143controller chips are also present on many new AMD/Opteron based systems,
144like the Sun 4100.
145Note that this controller can drive both SAS and SATA
146drives or a mix of them at the same time.
147The Integrated RAID Mirroring
148available for these controllers is poorly supported at best.
149.Pp
150The
151.Tn Fibre Channel
152controller chipset are supported by a broad variety of speeds and systems.
153The
154.Tn Apple
155Fibre Channel HBA is in fact the
156.Tn FC949ES
157card.
158.Pp
159This driver also supports target mode for Fibre Channel cards.
160This support may be enabled by setting the desired role of the core via
161the LSI Logic firmware utility that establishes what roles the card
162can take on - no separate compilation is required.
