4. SAS/SATA Capable Controller
Option Values: Disabled

ESRT2 (LSI*)
Intel

RSTe
Help Text:
- Intel
®
ESRT2: Provides host based RAID 0/1/10 and optional RAID 5. Uses Intel
®
ESRT2
drivers (based on LSI* MegaSR).
- Intel
®
RSTe: Provides pass-through drive support. Also provides host based RAID 0/1/10
support, and RAID 5 (in SATA mode only). Uses Intel
®
RSTe drivers.
Comments: This option selects the RAID stack to be used with the SCU. If Disabled is
selected, any drives connected to the SCU will not be usable.
Intel
®
ESRT2 provides host based RAID 0/1/10 and optional RAID 5. For a RAID 5 configuration, this
requires one of the Intel
®
RAID C600 Upgrade Keys AXXRKSATA4R5, AXXRKSATA8R5,
AXXRKSAS4R5, or AXXRKSAS8R5. Uses Intel
®
ESRT2 drivers (based on LSI* MegaSR), and is also
supported by Linux MDRAID.
Intel
®
RSTe provides pass-through drive support and provides host based RAID 0/1/10 support, and
RAID 5 (in SATA mode only). Uses Intel RSTe drivers in Windows, and MDRAID stack in Linux. The
Intel
®
RSTe RAID stack is required if it is necessary to provide pass-through support for non-RAID
drives, or if support is needed for more than 8 drives.

5. RSTe Boot Configuration
Option Values: Neither
AHCI Capable Ctrlr
SAS/SATA Capable Ctrlr
Help Text:
This selects the device that will support Bootable Drives, whether they are in RAID arrays or
individual pass-through SAS/SATA drives. Once selected and set up (if necessary), individual
bootable devices will be listed in the Bootable Devices menu display.
Comments: This option appears only when Intel
®
RSTe has been selected as the operational
mode on both the AHCI and SCU controllers. In that case there is a conflict and only one controller can
be selected as having bootable drives attached.
Once selected and set up (if necessary), individual bootable logical or physical drives available on the
selected controller will be listed in the Bootable Devices menu display.
If only one device selects RSTe, it will be available as a boot device along with any other devices – this
option is only necessary to distinguish between which RSTe device runs the Option ROM instance.
BIOS is required to designate the OPROM for the boot device selected here. Two iterations of the
OPROM cannot fully load simultaneously, and the version fully loaded will only show devices
connected to the given controller, so the OPROM load order is based on BIOS selecting the correct
device.
Note: If RSTe is selected, then only one CONTROLLER can be bootable, so there will be situations
where the boot drive *OR* an optical device will be bootable, but not both.
Please also see the product System Guide for restrictions on expander boot support.
