CAUTION
Step 1
Back up your data before you change your
system configuration. Otherwise, you might lose
data.
Unpack the RAID Controller
Unpack the RAID controller in a static-free
environment. Remove it from the antistatic bag,
and inspect it for damage. If the RAID controller
appears to be damaged, or if the MegaRAID
Universal Software Suite CD is missing, contact
LSI or your MegaRAID OEM support
representative.
Thank you for purchasing the MegaRAID® SAS 9240-4i
RAID controller or the MegaRAID SAS 9240-8i RAID
controller. Before you install your RAID controller, please
take a few minutes to read this quick installation guide. If you
need more information about any topic covered in this guide,
refer to the related documents on your MegaRAID Universal
Software Suite CD.

The MegaRAID SAS 9240-4i RAID controller and the
MegaRAID SAS 9240-8i RAID controller are PCI-Express
2.0, half-size, full-height RAID controllers based on the
LSISAS2008 PCI Express-SAS/SATA I/O Processor chip.
The MegaRAID SAS 9240-4i RAID controller controls four
internal 6-Gb/s SAS/SATA ports through one SFF-8087 SAS
x4 internal connector.
The MegaRAID SAS 9240-8i RAID controller controls eight
internal 6-Gb/s SAS/SATA ports through two SFF-8087 SAS
x4 internal connectors.
There are two differences between the SAS 9240-4i RAID
controller and the SAS 9240-8i RAID controller:
– The SAS 9240-4i supports four ports and the SAS
9240-8i supports eight ports.
– The SAS 9240-4i does not have the connector for
ports four through seven.
Note:
The CD contains utility programs, device drivers
for various operating systems, and the following
documentation:
SATA II is the only type of SATA supported by
these RAID controllers.
Step 2
Prepare the Computer
Turn off the computer, and unplug the power
cords from the rear of the power supply. Remove
the cover from the computer.
!
CAUTION
Step 3
Before you install the RAID controller, make sure
that the computer is disconnected from the power
and from any networks.
Review the Jumpers and the Connectors
Figure 1 shows the location of the jumpers and
the connectors on the SAS 9240-4i RAID
controller. The jumpers are set at the factory, and
you usually do not need to change them.

Step 4
Install the RAID Controller
Insert the RAID controller in a PCI Express slot
on the motherboard, as shown in Figure 3. Press
down gently, but firmly, to seat the card correctly
2 of 4
in the slot. Secure the RAID controller to the
computer chassis with the bracket screw.
Note:
Note:
Step 7
Reinstall the computer cover and reconnect the
power cords.
Some PCI Express slots support only PCI
Express graphics cards; if a RAID controller is
installed, it will not function.
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.
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.

SAS 9240-8i RAID Controller
Turn on the Power to the Computer
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:
Step 9
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.
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.
Step 5
Configure and Install the SAS Devices, SATA
II Devices, or Both in the Host Computer Case
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.
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.
SUPPORTED RAID LEVELS
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.
3 of 4
• RAID 1 (drive mirroring): Data is written simultaneously
to both drives in the drive group, providing complete data
redundancy if one drive fails. RAID 1 supports an even
number of drives from 2 to 32 in a single span.
• RAID 5 (drive striping with distributed parity): Data is
striped across all drives in the group. Part of the capacity
of each drive stores parity information that reconstructs
data if a drive fails. RAID 5 provides good data throughput
for applications with high read request rates.
• RAID 10 (RAID 1 and RAID 0 in spanned groups):
RAID 10 uses mirrored pairs of drives to provide complete
data redundancy. RAID 10 provides high data throughput
rates.
Note:
Refer to the MegaRAID SAS Software User’s
Guide on the MegaRAID Universal Software
Suite CD for more information about RAID levels.
