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 Storage Technology enterprise (RSTe) or the AVAGO 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 72
•
“Quick RAID setup using the AVAGO MegaRAID BIOS configuration utility ” on page 74
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 hard disk drives” on page 72
•
“Configuring SATA RAID functionality with the Intel RSTe configuration utility” on page 72
Installing SATA hard disk drives
Ensure that your computer has the minimum number of SATA 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 reading performance and 100% redundancy
• RAID Level 10 - Striped and mirrored disk array (a combination of RAID Level 0 and RAID Level 1)
– A RAID Level 10 hard disk drive group consisting of four hard disk drives
– Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, or 64 KB
• 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
Configuring SATA RAID functionality with the Intel RSTe configuration utility
This section describes the information about configuring SATA RAID functionality with the Intel RSTe
configuration utility.
Note:
The Intel RSTe configuration utility assumes that your computer is installed with more than one hard
disk drive. Therefore, if only one hard disk drive is installed in your computer, the following information
does not apply.
