RAID Support
®
The Intel
Workstation Board S5520SC 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
Server RAID Technology II feature provides RAID modes 0, 1, and 10.
If RAID 5 is needed, you must install the optional Intel
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.
