RAID Support The Intel® Server System SR2520SA is available in both fixed and redundant models. The fixed model has order code SR2520SAF/SR2520SAFR. The redundant model has order code SR2520SAX/SR2520SAXS and SR2520SAXR/SR2520SAXSR. For information on configuring RAID, see the RAID Software Guide that is included on the Intel® Server Deployment Toolkit 2.0 CD. SATA The Intel® Server Systems SR2520SAF/SR2520SAFR and SR2520SAX/SR2520SAXR provide an embedded SATA controller that supports both 1.5 and 3.0 Gbps data transfer rates. The BIOS Setup utility provides multiple drive configuration options on the Advanced | ATA Controller setup page, some of which affect the ability to configure RAID. The "Onboard SATA Controller" option is enabled by default. When this option is enabled, the "SATA Mode" option can be set to either Legacy or Enhanced. The Legacy and Enhanced modes affect the RAID configuration as follows: • Legacy supports four disk drives and does not provide RAID support. • Enhanced supports six disk drives and is required for RAID configurations. When the enhanced mode is selected, you can choose to enable or disable "AHCI Mode" or "Configure SATA as RAID". Intel® Embedded Server RAID Technology II is enabled by the option, "Configure SATA as RAID." The Intel® Embedded Server RAID Technology II feature provides RAID modes 0, 1, and 10. For RAID 0, 1, and 10, enclosure management is provided through the SATA_SGPIO connector on the server board when a cable is attached between this connector on the server board and to the backplane I2C interface. If RAID 5 is desired, the optional Intel® RAID Activation Key AXXRAKSW5 (available post-release) can be installed. To enable RAID 5, this activation key is placed on the SATA_Key connector that is located at the left side of the server board. For information on how to install the Intel® RAID Activation Key AXXRAKSW5 accessory to enable RAID 5, see the documentation that is included with the accessory kit. Notes: For assistance in navigating through the F2 BIOS Setup utility, see the Intel® Server Board S5000VSA Technical Product Specification. For information on setting up RAID, see the RAID Software Guide that is included on the Intel® Server Deployment Toolkit 2.0 CD. Intel® Server System SR2520SA User's Guide 15
