The \fBmr_sas\fR driver also supports the following Dell cards: PERC H700, H710, H710P, H800, and H810.
.SS "Configuration"
.sp
.LP
The uneditable \fBmr_sas.conf\fR file contains one user private configurable parameter, for MSI or MSI-X support. Configure your hardware through the related BIOS utility or the MegaCli Configuration Utility. If you want to install to a drive attached to a \fBmr_sas\fR HBA, create the virtual drive first from the BIOS (X86) before running Solaris install. The \fBMegaCli\fR utility can be downloaded from the LSI website. 
.sp
.LP
The LSI MegaRAID SAS device can support up to 64 virtual SAS2.0, SAS1.0, SATA3.0, or SATA 6.0 disks. The BIOS numbers the virtual disks as 1 through 64, however in Solaris these drives are numbered from 0 to 63. Also keep in mind that SAS and SATA drives can not be configured into the same virtual disk.
