NOTE:
If remapping is enabled in BIOS, M.2 SSDs may also appear in the disk list. M.2 SSDs and SATA
SSDs cannot be included in the same RAID volume.

If you are creating a RAID 0 (Striped Array), you can set Strip Size. Use the
Down
arrow to advance to this
entry, and then press
Enter
and use the
Down
arrow to select 128KB, and then press
Enter
.
8.
Press the
Down
arrow to advance past the Capacity (MB) setting. While it is possible to set capacity, HP
recommends using the defaults. The default for a RAID 1 is set to about 95% of the maximum possible
capacity. This allows you to replace a failed drive with a drive of the same capacity.

Press the
Down
arrow to advance to Create Volume and then press
Enter
. The screen changes to show
the active RAID volumes.

Press
Esc
twice to exit the configuration utility. The system reboots.
Configuring SATA RAID in Windows
This section explains how to use the Intel Rapid Storage Technology Utility to set up and manage SATA RAID
volumes in Windows. It is assumed that the Intel Rapid Storage Technology Graphical User Interface (GUI) has
been installed.
1.
Press the
Windows
key and start typing
Intel
. Intel Rapid Storage Technology displays in Programs.
Select Intel Rapid Storage Technology to start the Graphical User Interface (GUI). Alternatively, in
Windows 7 you can click the
Start
button at the lower left corner of the screen and navigate to Intel
Rapid Storage Technology.
2.
Click Yes (if prompted) to allow the application to make changes to your system.
3.
Click the Create button at the top of the window.
NOTE:
The Create option is only available if it is possible to create a RAID array. If you are adding a
drive to create a RAID array including data from an existing drive, you may need to shrink the size of the
main partition by 5 GB to free up space for RAID metadata on the drive. The create option does not
display if there is insufficient space for metadata. Use disk manager to shrink the last partition on the
disk. This is typically the Windows partition. If the last partition is a protected partition, shrinking the
Windows partition will allow RAID creation.
4.
Follow the prompts to proceed through the creation process.
5.
Close the Intel Rapid Storage Technology GUI.
6.
Remember to open the Disk Management snap-in to initialize and format the newly created array. The
new array is not visible until it is initialized and formatted.
Software RAID solution
This section summarizes software RAID considerations that are specific to the Linux environment, and
provides links to additional configuration resources.
Software RAID considerations
The Linux kernel software RAID driver (called md, for multiple device) offers integrated software RAID without
the need for additional hardware disk controllers or kernel patches. Unlike most hardware RAID solutions,
software RAID can be used with all types of disk technologies, including SATA, SCSI, and solid-state drives.
This software solution requires only minimal setup of the disks themselves.
However, when compared to hardware-based RAID, software RAID has disadvantages in managing the disks,
breaking up data as necessary, and managing parity data. The CPU must assume some extra loading: disk-
