Lenovo 4228, 4223 Configuring RAID with Intel RSTe, Installing Sata or SAS hard disk drives

Page 49

Chapter 7. 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 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 43

•“Quick RAID setup using the LSI MegaRAID BIOS configuration utility ” on page 45

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 43

•“Configuring SATA or SAS RAID functionality with the Intel RSTe configuration utility” on page 44

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 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

Ensure that one of the following hard disk drive enablement modules is installed in your computer:

•If zero to four SATA hard disk drives or solid state drives are installed, no hard disk drive enablement module is needed.
