Server Board Features Optional Hardware Intel® SAS Entry RAID Module AXX4SASMOD The Intel® Server Board S5520HC / 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 (Nonvolatile 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. Figure 8. Intel® 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. Intel® Server Board S5520HC and S5500HCV Service Guide 26
