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 71
•“Quick RAID setup using the LSI MegaRAID BIOS configuration utility” on page 73
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 71
•“Configuring SATA or SAS RAID functionality with Intel RSTe configuration utility” on page 72
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 -
–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.
