37 .Nd 3ware 9750 series SATA/SAS RAID controllers driver
39 To compile this driver into the kernel,
40 place the following lines in your
41 kernel configuration file:
42 .Bd -ragged -offset indent
47 Alternatively, to load the driver as a
48 module at boot time, place the following line in
50 .Bd -literal -offset indent
56 driver provides support for LSI's 3ware 9750 series
59 These controllers are available in 4, 8, 16 or 24-port configurations,
60 and support the following RAID levels: 0, 1, 10, 5, 50, 6.
61 The device nodes for the controllers are of the form
62 .Pa /dev/tws Ns Ar X ,
65 is the controller number.
66 The driver is implemented as a SCSI SIM
67 under CAM, and, as such, the logical units that it controls are accessible
72 is the logical unit number.
74 .Bl -tag -width indent
75 .It Va hw.tws.msi.enable
76 By default, the driver will use MSI if it is supported.
77 This behavior can be turned off by setting this tunable to 0.
82 driver supports the following SATA RAID controllers:
86 LSI's 3ware SAS 9750-4i
88 LSI's 3ware SAS 9750-4i4e
90 LSI's 3ware SAS 9750-8i
92 LSI's 3ware SAS 9750-8e
94 LSI's 3ware SAS 9750-16i4e
