RAID Support
The server system provides 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 or I2C interface.
If RAID 5 is desired, the optional Intel® RAID Activation Key AXXRAKSW5 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.
For information on configuring RAID, see the RAID software user’s guide that is included on the Intel® Server Deployment Toolkit 2.0 CD.
