- LSI MegaRAID FALCON SAS2.0 Controller HBA driver
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:
RAID levels 0, 1, and 5
RAID spans 10
Online Capacity Expansion (OCE)
Online RAID Level Migration (RLM)
Auto resume after loss of system power during array rebuild or reconstruction (RLM)
Configurable stripe size up to 64KB
Check Consistency for background data integrity
Patrol read for media scanning and repairing
16 logical drive support
Automatic rebuild
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 virtual disks as 1 through 16. In Solaris these drives are numbered from 0 to 15.
