Chapter 8. Configuring RAID

This chapter provides instructions on how to install hard disk drives and configure Redundant Array of
Independent Disks (RAID) for your computer. Depending on your computer model, RAID can be enabled by
Intel Rapid Store Technology enterprise (RSTe) or the LSI MegaRAID BIOS.
Note: The RAID configuration information described in this chapter is only applicable in the Windows
environment. For information about configuring RAID in the Linux environment, contact your Linux software
provider.
This chapter provides information about the following topics:
• "Configuring RAID with Intel RSTe" on page 81
• "Quick RAID setup using the LSI MegaRAID BIOS configuration utility" on page 83

Configuring RAID with Intel RSTe

If your computer comes with Intel RSTe, you can follow the sections below to configure RAID with Intel RSTe.
This section provides information about the following topics:
• "Installing SATA or SAS hard disk drives" on page 81
• "Configuring SATA or SAS RAID functionality with Intel RSTe configuration utility" on page 82

Installing SATA or SAS hard disk drives

Ensure that your computer has the minimum number of SATA or SAS hard disk drives installed for the
following supported levels of RAID:
• RAID Level 0 - Striped disk array
– A RAID Level 0 hard disk drive group consisting of at least two hard disk drives
– Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB
– Better performance without fault tolerance
• RAID Level 1 - Mirrored disk array
– A RAID Level 1 hard disk drive group consisting of two hard disk drives
– Improved read performance and 100% redundancy
• RAID Level 5 - Block-level striped disk array with distributed parity
– A RAID Level 5 hard disk drive group consisting of at least three hard disk drives
– Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, or 64 KB
– Better performance and fault tolerance
– RAID Level 5 by using Intel RSTe supports SATA hard disk drives only
Ensure that the correct hard disk drive enablement module is installed in your computer:
• If zero to three SATA hard disk drives or solid-state drives are installed, no hard disk drive enablement
module is needed.
• If there is any SAS hard disk drive installed, the SAS hard disk drive enablement module (one to three
hard disk drives) is required.
