32 .Nd Adaptec AdvancedRAID Controller driver
34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
42 To compile in debugging code:
43 .Cd options AAC_DEBUG=N
46 Alternatively, to load the driver as a
47 module at boot time, place the following line in
49 .Bd -literal -offset indent
55 driver provides support for the Adaptec AAC family of SCSI Ultra2, Ultra160,
56 and Ultra320, SATA and SAS RAID controllers.
58 Access to RAID containers is available via the
63 device enables the SCSI pass-thru interface and allows devices connected
64 to the card such as CD-ROMs to be available via the CAM
67 Note that not all cards allow this interface to be enabled.
71 device nodes provide access to the management interface of the controller.
72 One node exists per installed card.
77 exist for compatibilty with the Dell and HP versions of management tools,
79 If the kernel is compiled with the
85 modules are loaded, the
88 interface for the management device will be enabled and will allow
89 Linux-based management applications to control the card.
93 defaults to 65536 and may be set at boot time to another value via
95 This value determines the maximum data transfer size allowed
97 Setting it higher will result in better performance,
98 especially for large sequential access patterns.
101 of the card limit this value to 64K for arrays with many members.
102 While it may be safe to raise this value, this is done
103 .Em at the operator's own risk .
105 performance peaks at a value of 96K,
106 and drops off dramatically at 128K,
107 due to other limitations of the card.

214 will enable increasingly verbose debug messages.
216 The adapter can send status and alert messages asynchronously
218 These messages are printed on the system console,
219 and are also queued for retrieval by a management application.
230 driver first appeared in
234 .Aq msmith@FreeBSD.org
236 .Aq scottl@FreeBSD.org
238 This driver is not compatible with Dell controllers that have version 1.x
240 The firmware version is the same as the kernel version printed in the BIOS
241 POST and driver attach messages.
243 .\"This driver will not work on systems with more than 4GB of memory.
245 The controller is not actually paused on suspend/resume.
