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
2
C interface.
