Configuring Intel SATA RAID

This section describes how to use Intel
volumes.
NOTE:
These instructions apply to Windows-based systems. They also apply to Linux distributions that
include the isci kernel driver support for the RSTe technology. This driver is included on recent releases of
most upstream and enterprise distributions, and may be available for addition to some previous releases. If
this driver is not available in the distribution, or is not applicable to the platform (e.g., the RST controller), the
Software RAID solution is recommended.
You can create a SATA RAID array that contains up to the maximum number of internal SATA hard drives and
eSATA drives (if you use an optional eSATA bulkhead cable) supported on your workstation.
The Intel SATA option ROM configuration utilities run when you select RAID for the SATA emulation mode.
Two or more hard drives must be attached to the controller for the option ROM to run.

Configuring system BIOS

To set up a RAID configuration, the emulation mode must be set to RAID in Computer Setup (F10) Utility. This
is the default setting. If the mode has been changed, follow these steps to reinstate it.
