Introduction
After you have installed hardware components, you must fi rst confi gure the LSI
MegaRAID Software Utility before you install an operating system and other software drivers.
Note: If you do not wish to confi gure 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 Confi guration Utility adds RAID functional-
ity to enhance system effi ciency 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 confi guration into our product design, Supermicro
offers the user the benefi ts of software RAID confi guration 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 effi cient solution for data transfer, storage reliability and secu-
rity.

Support for BIOS Boot Specifi cation (BBS) (if available in the system BIOS)

1-2 RAID Modes Supported by the LSI 1068 Controller
SR Mode (Software RAID Mode)
This is the default mode. To use this mode, please do the following:
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 fl ash an IT mode fi rm-
ware 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.
•
Press <CTRL> + <M> to activate the SR mode.•
Note: Different RAID modes require different fi rmwares and drivers. Be
sure to download the correct RAID mode driver before installing it to the
OS. For fi rmware downloads and assistance, please contact Supermicro
Technical Support at www.supermicro.com or Support@supermicro.com.

LSI MegaRAID Confi guration for the LSI 1068 Controller User's Manual
1-3 RAID Level Review
To create a RAID storage confi guration, you will need to confi gure physical disk
drives into arrays fi rst. 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 Duplicate copy of Segment 2
Segment 3 Duplicate copy of Segment 3
Segment 4 Duplicate copy of Segment 4

Chapter 1: Introduction to the LSI MegaRAID Software Utility
RAID 10 (Striping + Mirroring)
RAID 10 combines RAID 0 and RAID 1 by fi rst 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
