31 .Nd Adaptec AdvancedRAID Controller driver
33 .Cd options AAC_DEBUG=N
40 driver provides support for the Adaptec AAC family of SCSI Ultra2, Ultra160,
41 and Ultra320, and SATA RAID controllers.
43 Access to RAID containers is available via the
48 device enables the SCSI pass-thru interface and allows devices connected
49 to the card such as CD-ROMs to be available via the CAM
52 Note that not all cards allow this interface to be enabled.
56 device nodes provide access to the management interface of the controller.
57 One node exists per installed card.
62 exist for compatibilty with the Dell and HP versions of management tools,
64 If the kernel is compiled with the
70 modules are loaded, the
73 interface for the management device will be enabled and will allow
74 Linux-based management applications to control the card.
78 defaults to 65536 and may be set at boot time to another value via
80 This value determines the maximum data transfer size allowed
82 Setting it higher will result in better performance,
83 especially for large sequential access patterns.
86 of the card limit this value to 64K for arrays with many members.
87 While it may be safe to raise this value, this is done
88 .Em at the operator's own risk .
90 performance peaks at a value of 96K,
91 and drops off dramatically at 128K,
92 due to other limitations of the card.

147 will enable increasingly verbose debug messages.
149 The adapter can send status and alert messages asynchronously
151 These messages are printed on the system console,
152 and are also queued for retrieval by a management application.
163 driver first appeared in
167 .Aq msmith@FreeBSD.org
169 .Aq scottl@FreeBSD.org
171 This driver is not compatible with Dell controllers that have version 1.x
173 The firmware version is the same as the kernel version printed in the BIOS
174 POST and driver attach messages.
176 The controller is not actually paused on suspend/resume.
