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
Configuring SATA or SAS RAID functionality with the Intel RSTe configuration utility
This section describes the information about configuring SATA or SAS 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.
This section provides information about the following topics:
• "Entering the Intel RSTe configuration utility" on page 42
• "Creating RAID volumes using the Intel RSTe configuration utility" on page 43
• "Deleting RAID volumes using the Intel RSTe configuration utility" on page 43
• "Resetting hard disk drives to non-RAID" on page 43
Entering the Intel RSTe configuration utility
This section provides instructions on how to enter the Intel RSTe configuration utility.
During the computer startup, follow the instructions on the screen. Press Ctrl+I to enter the Intel RSTe
configuration utility.
