NAME
       imraid_sas - LSI MegaRAID FALCON SAS2.0 Controller HBA driver

DESCRIPTION
       The  imraid_sas	MegaRAID  FALCON  SAS2.0  controller  host bus adapter
       driver is a SCSA-compliant nexus driver that supports the LSI  MegaRAID
       FALCON SAS 92xx series of controllers.

       FALCON  HBA supports up to 64 JBOD drives which are directly exposed to
       OS.

       Some of the RAID Features include the following:

	   o	  RAID levels 0, 1, and 5

	   o	  RAID spans 10

	   o	  Online Capacity Expansion (OCE)

	   o	  Online RAID Level Migration (RLM)

	   o	  Auto resume after loss of system power during array  rebuild
		  or reconstruction (RLM)

	   o	  Configurable stripe size up to 64KB

	   o	  Check Consistency for background data integrity

	   o	  Patrol read for media scanning and repairing

	   o	  16 logical drive support

	   o	  Automatic rebuild

	   o	  Global and dedicated Hot Spare support

       The imraid_sas.conf file consists a user tunable parameter to configure
       MSI or MSI-X support in the imraid_sas driver. Pre-boot applications or
       MegaCli	can  be	 used to configure the HBA. The MegaCli utility can be
       downloaded from the LSI website. To install the operating system on the
       drives  attached to the FALCON HBA, either creates a virtual drive or a
       JBOD drive from the pre-boot application.

       The LSI MegaRAID FALCON	SAS  device  can  support  up  to  16  virtual
       SAS2.0,	SAS1.0,	 SATA3.0, or SATA 6.0 disks. The BIOS numbers the vir‐
       tual  disks as 1 through 16. In Solaris these drives are numbered  from
       0 to 15.

NOTES
       JBOD drives do not qualify for any of the RAID processing.

       The  imraid_sas	driver	only  supports internal and external expanders
       that are not fully SAS1.0 or fully SAS2.0 compliant.
