Step 7

Turn on the Power to the Computer

Replace the computer cover and reconnect the
power cord(s). Turn on the power to the
computer. During boot, a MegaRAID BIOS
message displays.

The firmware takes several seconds to initialize.
During this time the adapter scans the Serial ATA
ports.

Step 8

Configure Physical Arrays and Logical Drives

Run a MegaRAID utility to configure the physical
arrays and the logical drives. The MegaRAID
BIOS configuration tools are the BIOS
Configuration Utility (CU) and the WebBIOS CU.
You can use either utility to configure RAID
arrays.

To start the BIOS CU, press CTRL+M when
prompted during system boot-up. To start the
WebBIOS CU, press CTRL+H when prompted
during system boot-up. See the MegaRAID
Software Configuration User’s Guide
on the
MegaRAID Universal Software Suite CD for
information about using these utilities.

Step 9

Install the Operating System Driver

The MegaRAID SATA 150-6 RAID controller can
operate under various operating systems. To
operate under these operating systems, you must
install the software drivers.

The MegaRAID Universal Software Suite CD
includes the drivers for the supported operating
systems. You can view the supported operating
systems and download the latest drivers for RAID
adapters on the LSI Logic web site at

http://www.lsilogic.com/cm/DownloadSearch.do

.

Access the download center and follow the steps
to download the driver.

Refer to the MegaRAID Device Driver Installation
User’s Guide
on the Universal Software Suite CD
for details on installing the driver. Be sure to use
the latest Service Packs provided by the
operating system manufacturer and to review the
readme

file that accompanies the driver.

The MegaRAID SATA 150-6 RAID Controller supports disk
arrays using the following RAID levels:

RAID 0 (Data Striping): Data is striped across all disks

in the array, enabling fast data throughput. There is no
data redundancy. All data is lost if any disk fails.

RAID 1 (Disk Mirroring): Data is written simultaneously

to two disks, providing complete data redundancy if one
disk fails. The maximum array capacity is equal to the
available size of the smaller of the two hard drives.

RAID 5 (Disk Striping with Distributed Parity): Data is

striped across all disks in the array. Part of the capacity
of each disk stores parity information that reconstructs
data if a disk fails. Provides good data throughput for
applications with high read request rates.

RAID 10 (RAID 1 and RAID 0 in Spanned Arrays): Uses

mirrored pairs of disks to provide complete data
redundancy. Provides high data throughput rates.

RAID 50 (RAID 5 and RAID 0 in Spanned Arrays): Uses

both parity and disk striping across multiple disks to
provide complete data redundancy. Provides high data
throughput rates.

Note:

For more information about RAID levels, refer to
the MegaRAID Configuration Software User’s
Guide
on the MegaRAID Universal Software Suite
CD.
