- LSI MegaRAID SAS2.0 Controller HBA driver
The mr_sas MegaRAID SAS2.0 controller host bus adapter driver is a SCSA-compliant nexus driver that supports the LSI SAS2208-based series of controllers running MegaRAID firmware, the LSI SAS2108-based series of MegaRAID controllers, and the Sun StorageTek 6Gb/s SAS RAID HBA series of controllers.
Some of the RAID Features include the following:
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)
Configurable stripe size up to 1MB
Check Consistency for background data integrity
Patrol read for media scanning and repairing
64 logical drive support
Up to 64TB LUN support
Global and dedicated Hot Spare support
The mr_sas driver also supports the following Dell cards: PERC H700, H710, H710P, H800, and H810.
The uneditable mr_sas.conf 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 mr_sas HBA, create the virtual drive first from the BIOS (X86) before running Solaris install. The MegaCli utility can be downloaded from the LSI website.
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.
