NAME

     ida -- Compaq Intelligent Drive Array Controllers

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device ida

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   ida_load="YES"

DESCRIPTION

     The Compaq Intelligent Drive Array (IDA) technology is used to distribute data across an array of hard drives.  It unites these hard drives
     into one or more high-performance logical drives.	The drive array is managed by an array controller.

     These controllers have the ability to provide fault tolerance for the connected drives and optionally provide write cache for the logical
     drives.  It is also possible for an application to access the SCSI bus subsystem directly by using the pass-through interface.

HARDWARE

     The following controllers are supported by the ida driver:

     o	 Compaq SMART Array 221
     o	 Compaq Integrated SMART Array Controller
     o	 Compaq SMART Array 4200
     o	 Compaq SMART Array 4250ES
     o	 Compaq SMART 3200 Controller
     o	 Compaq SMART 3100ES Controller
     o	 Compaq SMART-2/DH Controller
     o	 Compaq SMART-2/SL Controller
     o	 Compaq SMART-2/P Controller
     o	 Compaq SMART-2/E Controller
     o	 Compaq SMART Controller

IMPLEMENTATION NOTES

     Extreme caution should be exercised when using the pass-through interface.  It is possible to interfere with normal system I/O and cause
     hangs if pass-through is used to an active device.  Pass-through should only be used to a device that is otherwise quiescent.

NAME

     arcmsr -- Areca RAID Controller driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device pci
	   device scbus
	   device da
	   device arcmsr

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   arcmsr_load="YES"

DESCRIPTION

     The arcmsr driver provides support for the Areca ARC-11xx, ARC-12xx, ARC-13xx, ARC-16xx and ARC-18xx series of SAS and SATA RAID controllers.
     These controllers feature RAID-0, 1, 3, 5, 6, and 10 and JBOD acceleration for up to 16 SATA drives.  RAID level and stripe level migration,
     online capacity expansion, hot insertion/removal, automatic failover and rebuild, and SMART are also supported.  Access to the arrays is pro-
     vided via the SCSI CAM /dev/da? device nodes.  A management interface is also present via the /dev/arcmsr? device node.  Management tools for
     i386 and amd64 are available from Areca.

     The arcmsr driver supports the following cards:

     o	 ARC-1110
     o	 ARC-1120
     o	 ARC-1130

HISTORY

     The arcmsr driver first appeared in FreeBSD 5.4.

AUTHORS

     The driver was written by Erich Chen <erich@areca.com.tw>.

BUGS

     The driver has been tested on i386 and amd64.  It likely requires additional work to function on big-endian architectures.
