NAME

       mega_sas - SCSI HBA driver for LSI MegaRAID SAS controller

DESCRIPTION

       The mega_sas MegaRAID controller host bus adapter driver  is a  SCSA-compliant  nexus  driver that supports the Dell PERC 5/E, 5/i, 6/E and
       6/i RAID controllers, the IBM ServeRAID-MR10k SAS/SATA  controller and  the  LSI  MegaRAID  SAS/SATA  8308ELP,  8344ELP,  84016E,  8408ELP,
       8480ELP, 8704ELP, 8704EM2, 8708ELP, 8708EM2, 8880EM2 and 8888ELP series of controllers.

       Supported  RAID	features  include RAID levels 0, 1, 5, and 6, RAID spans 10, 50 and 60, online capacity expansion (OCE), online RAID level
       migration (RLM), auto resume after loss of  system power during arrays, array rebuild or reconstruction (RLM) and configurable stripe  size
       up  to  1MB. Additional supported RAID features include check consistency for background data integrity, patrol read for media scanning and
       repairing, 64 logical drive support, up to 64TB LUN support, automatic rebuild and global and dedicated hot spare support.

CONFIGURATION

       The mega_sas.conf file contains no user configurable parameters. Please configure your hardware through the related  BIOS  utility  or  the
       MegaCli	configuration  utility.  If  you  want to install to a drive attached to a mega_sas HBA, you should create the virtual drive first
       from the BIOS before running the Solaris install. You can obtain the MegaCli utility from the LSI website.

       The mega_sas device can support up to  64 virtual disks. Note that BIOS numbers the virtual disks as 1 through 64, however in  the  Solaris
       operating  environment virtual disks are numbered from 0 to 63.	Also note that SAS and SATA drives cannot be configured into the same vir-
       tual disk.

KNOWN PROBLEMS AND LIMITATIONS

       The mega_sas driver does not support the LSI MegaRAID SAS 8204ELP, 8204XLP, 8208ELP, and 8208XLP controllers.

NAME

       ahci - Advanced Host Controller Interface SATA controller driver

SYNOPSIS

       sata@unit-address

DESCRIPTION

       The ahci driver is a SATA framework-compliant HBA driver that supports SATA HBA controllers that are compatible with the Advanced Host Con-
       troller Interface 1.0 specification. AHCI is an Intel-developed protocol that describes the register-level interface for  host  controllers
       for  serial  ATA  1.0a  and Serial ATA II. The AHCI 1.0 specification describes the interface between the system software and the host con-
       troller hardware.

       The ahci driver currently supports the Intel ICH6/7/8/9, VIA vt8251 and JMicron AHCI controllers which are compliant with the Advanced Host
       Controller  Interface  1.0  specification.  Note that while the	Intel ICH6/7/8/9, VIA vt8251 and JMicron AHCI controllers support standard
       SATA features, the ahci driver currently only supports hard disk, ATAPI SATA DVD, hotplug and NCQ (Native command queuing). Port multiplier
       and power management  are not yet supported.

CONFIGURATION

       The ahci module contains no user configurable parameters.

NOTES

       To bind the ahci driver to your controller, choose the [AHCI] BIOS option.

       Note that booting is not supported if toggle exists between the [IDE] and [AHCI] BIOS options
