RAID Support
The Intel
®
Server Board S5500WB provides an integrated SATA II host controller that
supports independent DMA operation on the six Ports and supports data transfer rates of
up to 3.0 Gb/Sec.
The ICH10R provides support for Intel
®
Matrix Storage Technology, providing both
AHCI and integrated RAID functionality. The industry-leading RAID capability provides
high-performance RAID 0, 1, 5 and 10 functionality on up to six SATA ports.
The BIOS Setup utility provides multiple drive configuration options on the Advanced |
Mass Storage Controller Configuration 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 ENHANCED mode,
COMPATIBILITY mode, AHCI mode or SW RAID mode. The modes affect the
configuration as follows:
•
ENHANCED mode supports up to six SATA ports with IDE Native Mode.
•
COMPATIBILITY mode supports up to four SATA ports[0/1/2/3] with IDE Legacy
mode and 2 SATA ports[4/5] with IDE Native Mode.
•
AHCI mode supports all SATA ports using the Advanced Host Controller Interface
when the option is enabled.
Note: For AHCI capability in EFI, the AHCI legacy Option ROM should be set to “disabled”.
•
SW RAID mode supports configuration of SATA ports for RAID via RAID
configuration software.
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 right 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.
