in the slot. Secure the RAID controller to the
computer chassis with the bracket screw.
Note:
Some PCI Express slots support only PCI
Express graphics cards; if a RAID controller is
installed, it will not function.
Note:
These controllers also work in PCI Express first
generation slots. The PCI Express software is
backward compatible with previous revisions of
the PCI bus and the PCI-X bus. Refer to the
guide for your motherboard for information about
the PCI Express slot.

Step 5
Configure and Install the SAS Devices, SATA
II Devices, or Both in the Host Computer Case
Refer to the documentation for the devices for any
preinstallation configuration requirements.
Step 6
Connect the RAID Controller to the SAS
Devices, SATA II Devices, or Both in the Host
Computer Case
Use SAS cables to connect the RAID controller to
SAS devices, SATA II devices, or both. See
Figure 1
or
Figure 2
to view the connector
locations, depending on which controller you
have.
Note:
Refer to the
MegaRAID 6Gb/s SAS RAID
Controllers User’s Guide
on the
MegaRAID
Universal Software Suite
CD for detailed
information about the SAS cables.
Step 7
Turn on the Power to the Computer
Reinstall the computer cover and reconnect the
power cords.
Turn on power to the computer, making sure that
the power is turned on to the SAS devices and
the SATA II devices before or at the same time
that the power to the host computer is turned on.
If the power is turned on to the computer before
it is turned on to the devices, the computer might
not recognize the devices.
The firmware takes several seconds to initialize.
During this time, the controller scans the ports.
Step 8
Run the WebBIOS Configuration Utility
Run the WebBIOS Configuration Utility to
configure the groups and the virtual drives. When
the message
Press
<Ctrl><H> for WebBIOS
appears on the screen, immediately press
CTRL+H to run the utility.
Note:
Refer to the
MegaRAID SAS Software User’s
Guide
on the
MegaRAID Universal Software
Suite
CD for detailed steps on configuring groups
and virtual drives.
Step 9
Install the Operating System Driver
The controller can operate under various
operating systems, but you must install the
software drivers first.
The
MegaRAID Universal Software Suite
CD
includes the software drivers for the supported
operating systems, along with documentation.
You can view the supported operating systems
and download the latest drivers for RAID
controllers from the LSI web site at:
http://www.lsi.com/cm/DownloadSearch.do
.
Access the download center, and follow the steps
to download the driver.
Refer to the
MegaRAID SAS Device Driver
Installation User’s Guide
on the
MegaRAID
Universal Software Suite
CD for more information
about installing the driver. Be sure to use the
latest service packs that are provided by the
operating system manufacturer and to review the
readme
file that accompanies the driver.
S U P P O R T E D R A I D L E V E L S
The SAS 9240-4i RAID controller and the SAS 9240-8i RAID
controller support drive groups using the following RAID
levels:
•
RAID 0 (data striping):
Data is striped across all drives
in the group, enabling very fast data throughput. There is
no data redundancy. All data is lost if any drive fails.
