Introduction
After you have installed hardware components, you must first configure the LSI
MegaRAID Software Utility before you install an operating system and other software drivers.
Note: If you do not wish to configure LSI Software RAID settings, please
proceed with the OS installation. For OS installation instructions, refer to
related documents posted on our web site at www. supermicro.com.
1-1 Introduction to the LSI MegaRAID Software Utility
for the LSI 1068 Controller
The LSI Embedded MegaRAID Software Configuration Utility adds RAID functionality to enhance system efficiency and data security by supporting RAID 0, RAID 1,
RAID 10 and RAID 5 (via I-Button). RAID 0 (striping) can greatly enhance hard disk
I/O performance by striping data across multiple drives. RAID 1 (mirroring) allows
data to be simultaneously written to multiple drives, thus increases data integrity.
RAID 10, combining RAID 0 and RAID1, provides superb system performance
and system security. When used with an I-Button, the LSI MegaRAID Utility also
supports RAID 5, which implements block-level striping with parity data distributed
across all disks, achieving greater data redundancy at a lower cost. By incorporating the LSI MegaRAID Software configuration into our product design, Supermicro
offers the user the benefits of software RAID configuration without the high costs
associated with hardware RAID applications.
The LSI Embedded MegaRAID Software Utility supports up to eight SAS or SATA
ports, providing an efficient solution for data transfer, storage reliability and security.

Install a Software RAID Mode Driver in the OS.
•
Create RAID 0, RAID 1, and RAID 10 via the WebBIOS Utility so that the OS
can detect the hard disk drives installed in the system.
•
Buy an I-Button (AOC-IButton68) from Supermicro to enable RAID 5 support.
(Please refer to http://www.supermicro.com/products/accessories/addon/AOC-IButton68.cfm for more information on the AOC-Button68.)
AOC-IButton68
IT Mode (Initiator and Target Mode)
This is a Non-RAID mode. To use this mode, be sure to flash an IT mode firmware to the EEPROM and to install an IT Mode driver to the system OS. (See
the note below.)
To Activate RAID Modes
You can activate a RAID mode by pressing any key in the BIOS setup.
•
Press <CTRL> + <C> to activate the IT mode.
•

RAID Level Review
To create a RAID storage configuration, you will need to configure physical disk
drives into arrays first. An array is a group of one ~ eight physical disks that is seen
as one large disk drive (logical drive) by the host computer system. Only one RAID
level can be assigned to an array.
•
A RAID 0 array consists of one ~ eight physical drives.
•
A RAID 1 array consists of two physical drives
•
A RAID 10 array consists of four, six or eight physical drives.
Warning: Do not use both SAS and SATA drives in the same array to
avoid system malfunctioning or decreasing Mean Time Between Failures
(MTBF).
RAID 0 (Striping)
RAID 0 provides disk striping across all disk drives in an array. It does not provide
data redundancy, but it offers the best RAID performance.
RAID 0 Requires 1~8 Disk Drives
RAID 0 Example with 2 Disks
Disk Drive A
Disk Drive B
Segment 1
Segment 2
Segment 3
Segment 4
Segment 5
Segment 6
Segment 7
Segment 8
RAID 1 (Mirroring)
RAID 1 creates a duplicate copy of data by copying all data from one drive to another. It provides data redundancy, but it doubles data storage capacity requirement.
RAID 1 Requires a minimum of 2 Disk Drives
RAID 1 Example with 2 Disks
Disk Drive A
Disk Drive B
Segment 1
Duplicate copy of Segment 1
Segment 2

Chapter 1: Introduction to the LSI MegaRAID Software Utility
RAID 10 (Striping + Mirroring)
RAID 10 combines RAID 0 and RAID 1 by first breaking down data into smaller
segments and stripping these segments to each RAID1 set. Each RAID 1 set,
then duplicates its data to its mirrored drive.
RAID 10 provides the best RAID performance and best data security.
RAID 10 Requires 2, 4 or 6 Disk Drives
RAID 10 Example with 4 Disk Drives

redundant array offline, so a hotspare drive can automatically replace it.
Please note that an auto rebuild will begin immediately when the LSI MegaRAID finds an available hotspare drive to replace the drive that is offline.
1. From the LSI MegaRAID Main Menu, select Objects and press <Enter>.
2. When the Objects submenu appears, select Physical Drive and press <Enter>.
3. When the screen of all available Physical Drives appears as shown on the
bottom of Page 2-21, using the arrow keys to select the drive you wish to
force online or offline and press <Enter>.
4. A screen with Configuration Setting Options for the drive you selected will
appear. Using the arrow keys, select Online or Offline and Press <Enter>. If
you have selected Offline and pressed <Enter>, a screen similar to the one
shown below will appear.
5. Select Yes to proceed with the configuration. Select No to cancel the selection.

2-10 Checking Data Consistency of a Disk Drive
The LSI MegaRAID Software allows the user to check data consistency between the
source drive and its mirrored drive (the target drive) for RAID 1 or RAID 10 arrays.
Any differences found between these two drives will be automatically corrected if
you run Check Consistency.
Checking Data Consistency
Follow the steps below to check data consistency between the source drive and
the mirrored drive for RAID 1 and RAID 10 arrays.
1. From the LSI Main Menu, select Check Consistency and press <Enter>.
2. A list of configured virtual drives will be displayed. Using the up/down arrow
keys, select the virtual drive for which you wish to check data consistency
and press <Spacebar>.
Note: If a RAID 0 drive has been selected, a message will appear, indicating that Check Consistency cannot be performed. To continue, deselect
this drive, select a redundant drive and press <Spacebar> again.
