Optional Hardware
Intel
®
SAS Entry RAID Module AXX4SASMOD
The Intel
®
Server System SC5650HCBRP provides 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
six hard drives in the Intel
®
Server System SC5650HCBRP.
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 non-expander backplane drive
LED control.
/
NOTE
Neither SGPIO nor SES connections are required in the Intel
®
Server System SC5650HCBRP for the
expander backplane LED control
The PCI Express* Gen 1 slot (x8 Mechanically, x4 Electrically) is not available when the Intel
®
SAS Entry RAID
Module AXX4SASMOD is installed and vice versa.
