RAID Support
The Intel
®
Workstation System SC5650SCWS provides an embedded SATA controller that supports both 1.5
Gbps and 3.0 Gbps data transfer rates.
The BIOS Setup Utility provides drive configuration options on the Advanced | Mass Storage Controller
Configuration setup page, some of which affect the ability to configure RAID. The “On-board SATA Controller”
option is enabled by default and when enabled, you can set the “SATA Mode” option to one of the following
four modes:
“Enhanced” – Enhanced Mode supports up to six SATA ports with IDE native Mode.
“Compatibility” – Supports up to four SATA ports [0/1/2/3] with IDE Legacy mode and two SATA ports
[4/5] with IDE Native Mode.
“AHCI” – Supports all SATA ports using the Advanced Host Controller Interface.
“SW RAID” – Intel
®
Embedded Workstation RAID Technology II is enabled by “SW RAID” mode. The
Intel
®
Embedded Workstation RAID Technology II feature provides RAID modes 0, 1, and 10.
If RAID 5 is needed, you must install the optional Intel
®
RAID Activation Key AXXRAKSW5 accessory. This
activation key is placed on the SATA_ RAID_5_Key connector located on the left side of the workstation board.
For installation instructions, see the documentation included with the activation key.
