Optional Hardware
Intel
®
SAS Entry RAID Module AXX4SASMOD
The Intel
®
Server Board S5520HC/S5520HCT/S5500HCV provide a SAS module slot (J2J1) for the installation
of an optional Intel
®
SAS Entry RAID Module AXX4SASMOD. Once the optional Intel
®
SAS Entry RAID
Module AXX4SASMOD is present, the x4 PCI Express* links from the ICH10R to PCI Express* Slot 2 (x8
mechanically, x4 electrically) switches to the SAS module slot.
The optional Intel
®
SAS Entry RAID Module AXX4SASMOD includes a SAS1064e controller that supports x4
PCI Express* link widths and is a single-function PCI Express* end-point device. The SAS controller supports
the SAS protocol as described in the Serial Attached SCSI (SAS) Standard, version 1.0, and also supports
SAS 1.1 features. A 32-bit external memory bus off the SAS1064e controller provides an interface for Flash
ROM and NVSRAM (Non-volatile Static Random Access Memory) devices.
The optional Intel
®
SAS Entry RAID Module AXX4SASMOD provides four SAS connectors that support up to
four hard drives with a non-expander backplane or up to eight hard drives with an expander backplane.
The optional Intel
®
SAS Entry RAID Module AXX4SASMOD also provides a SGPIO (Serial General Purpose
Input/Output) connector and a SCSI Enclosure Services (SES) connector for backplane drive LED control.

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.
