SAS Entry RAID Module
SAS RAID Support
The BIOS Setup Utility provides drive configuration options on the Advanced | Mass Storage Controller
Configuration setup page for the Intel
®
SAS Entry RAID Module AXX4SASMOD, some of which affect the
ability to configure RAID.
The “Intel
®
SAS Entry RAID Module” option is enabled by default once the Intel
®
SAS Entry RAID Module
AXX4SASMOD is present. When enabled, you can set the “Configure Intel
®
SAS Entry RAID Module” to either
“LSI* Integrated RAID” or “Intel
®
ESRTII” mode.
IT/IR RAID Mode
Supports entry hardware RAID 0, RAID 1, and RAID10/10E and native SAS pass through mode.
Intel
®
ESRTII Mode
The Intel
®
Embedded Server RAID Technology II (Intel
®
ESRTII) feature provides RAID modes 0, 1, and 10. If
RAID 5 is needed with Intel
®
ESRTII, you must install the optional Intel
®
RAID Activation Key AXXRAKSW5
accessory. This activation key is placed on the SAS Software RAID 5 connector located on the Intel
®
SAS
Entry RAID Module AXX4SASMOD. For installation instructions, see the documentation included with the SAS
Module AXX4SASMOD and the activation key.
When Intel
®
Embedded Server RAID Technology II is enabled with the SAS Module AXX4SASMOD,
enclosure management is provided through the SAS_SGPIO or SES connector on the SAS Module
AXX4SASMOD when a cable is attached between this connector and the backplane or I
