MegaRAID®SAS 8344ELP
RAID Controller
Quick Installation Guide
Step 2 Prepare the Computer
Thank you for purchasing the MegaRAID®SAS (Serial
Attached SCSI/Serial ATA) 8344ELP (PCI Express low-profile)
RAID Controller. Please take a few minutes to read this quick
installation guide before you install the controller. If you need
more information about any topic covered in this guide, refer
to the related documents on your MegaRAID Universal
Software Suite CD.
Note: This is a PCI Express x4 card, so it fits only in a
PCI Express x4 or greater slot.
Note: SATA II is the only type of SATA supported by the
SAS 8344ELP Controller.
You can use the intelligent Battery Backup Unit 01
(LSIiBBU01) with the SAS 8344ELP. For more information
about this battery, refer to the MegaRAID Battery Backup Unit
User’s Guide on the MegaRAID Universal Software Suite CD.
MegaRAID SAS 8344ELP RAID CONTROLLER INSTALLATION
Make a backup of your data before you change
!
CAUTION
Step 1 Unpack the MegaRAID SAS 8344ELP RAID
your system configuration. Otherwise, you may
lose data.
Controller
Unpack the controller in a static-free environment.
Remove it from the antistatic bag and inspect it for
damage.

missing, contact LSI Logic or your MegaRAID
OEM support representative.
CAUTION
Step 3 Review the Jumpers and Connectors
Figure 1 MegaRAID SAS 8344ELP RAID Controller

Ports 0–3.
The ports connect the cables from
the adapter to SAS or SATA II physical drives, or a port multiplier.
2-pin header.
The BIOS function is enabled or dis-
abled in software depending on the
status of this jumper.
No jumper: BIOS is enabled (default).
Jumper: BIOS is disabled.
Note: The card does not function as
a RAID controller if this jumper is
mounted.
4-pin header.
Used for diagnostic purposes.
The serial port is not RS232 voltage
level compliant.
2-pin connector.
If thefirmwareflashed onto the board
is corrupted, you need to jumper J4
(this holds the CPU core in reset), so
you can flash the firmware. Remove
the jumper after you flash the new
firmware.
No jumper: This is the setting during
normal operation (Mode 3). This is
the default.
Jumper: This holds the CPU core in
reset (Mode 0).
Note: The card does not function as
a RAID controller if this jumper is
mounted.
16-pin (8x2) header.
Provides LEDinterface individually to
eight SATA II ports. The LED indicates activity on specific ports.

Provides a signalthat indicates when
the on-board cache contains data

Ports 4–7.
The ports connect the cables from
the adapter to the SATA II physical
drives or port multiplier.
20-pin connector.
Provides interface to the remote bat-
tery pack.
Step 4 Install the MegaRAID SAS 8344ELP RAID
Controller
Insert the SAS 8344ELP in a PCI-E slot on the
mainboard, as shown in Figure 2. Press down
gently but firmly to seat the card properly in the
slot. Secure the SAS 8344ELP to the computer
chassis with the bracket screw.

Step 5 Configure and Install SAS and/or SATA II
Devices
Configure the SAS and/or SATA II devices and
install them in the host system computer case.
Refer tothedocumentationfor the devices forany
pre-installation configuration requirements.
Step 6 Connect the MegaRAID SAS 8344ELP RAID
Controller to the SAS and/or SATA II Devices
Use SAS cables to connect the SAS 8344ELP to
SAS and/or SATA II devices. Refer to Figure 1 to
view connector locations on the controller.
Refer to the MegaRAID SAS Storage Adapters
User’s Guide on the MegaRAID Universal
Software Suite CD for detailed information about
the SAS cables.

Step 7 Power-Up the Computer
Replace the computer cover and reconnect the
power cord(s). Turn on power to the computer.
Ensure that the devices are powered up before or
at the same time as the host computer. If the
computer is powered up before the devices, the
devices might not be recognized.
During boot, a MegaRAID BIOS message similar
to the following displays:
LSI LOGIC MEGARAID BIOS VERSION xxxx
[date]
Copyright (c) 2005, LSI Logic Corp.
HA-1 (Bus x Dev y) LSI MegaRAID SAS
8344ELP PCI-E
Standard FW xxxx DRAM=xxx MB(SDRAM)
The firmware takes several seconds to initialize.
During this time the adapter scans the Serial ATA
ports.
Step 8 Run the WebBIOS Configuration Utility
Run the WebBIOS Configuration Utility to
configure the physical arrays and logical drives.
When the message Press <Ctrl><H> for
WebBIOS displays on the screen, press CTRL+H
immediately 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
physical arrays and logical drives.
Step 9 Install the Operating System Driver
The SAS 8344ELP can operate under various
operating systems. To operate under these
operating systems, you must install software
drivers.
The MegaRAID Universal Software Suite CD
includes drivers for the supported operating
systems, along with documentation. 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/downloads/main.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 details on
installing the driver. Be sure to use the latest
Service Packs provided by the operating system
manufacturer and review the readme file that
accompanies the driver.
SUPPORTED RAID LEVELS
The SAS 8344ELP supports disk arrays using the following
RAID levels:
• RAID 0 (Data striping): Data is striped across all disks
in the array, enabling very 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.
