Thank you for purchasing the MegaRAID® SAS (Serial
Attached SCSI/Serial ATA II) 8888ELP (PCI Express, low
profile) RAID controller. The MegaRAID SAS 8888ELP RAID
controller supports eight ports.
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
documents on your MegaRAID Universal Software Suite CD.
Important
You can use the intelligent Battery Backup Unit 01
(LSIiBBU01), intelligent Battery Backup Unit 05 (LSIiBBU05),
or the intelligent Transportable Battery Backup Unit 03
(LSIiBBU03) with the MegaRAID SAS 8888ELP RAID
controller. The battery backup unit has to be secured in the
system and connected to the back of the RAID controller
with a 20-pin cable. For more information about this battery,
refer to the Intelligent Battery Backup Units for 1078-based
MegaRAID Products User’s Guide on the MegaRAID
Universal Software Suite CD.
: SATA II is the only type of SATA supported by the
MegaRAID SAS 8888ELP RAID controller.

Turn off the computer and unplug the power cords
from the back of the power supply. Remove the
cover from the computer.
Before you install the controller, make sure that
the computer is disconnected from the power and
from any networks.
Figure 1 shows the location of the jumpers and
the connectors on the SAS 8888ELP 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 mainboard, as shown in Figure 2. Press
down gently but firmly to seat the card correctly
in the slot. Secure the RAID controller to the
computer chassis with the bracket screw.
Important
: Refer to your mainboard guide for information
about the PCI Express slot.
Important
: This is a PCI Express x8 card and can operate in
4x, 8x, and 16x slots.

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
pre-installation configuration requirements.
Step 6 Connect the RAID Controller to the SAS
Devices, SATA II Devices, or Both
Use SAS cables to connect the SAS RAID
controller to SAS devices, SATA II devices, or
both. Refer to Figure 1 to view connector
locations on the controller.
Refer to the MegaRAID 1078-based 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 the power to the computer.
Make 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 adapter scans the ports.
Step 8 Run the WebBIOS Configuration Utility
Run the WebBIOS Configuration Utility to
configure the physical arrays and the logical
drives. When the message Press <Ctrl><H> for
WebBIOS appears on the screen, immediately
press CTRL+H to run the utility.
Important
: 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 RAID 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
adapters on 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 details on
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.
data if a disk fails. RAID 5 provides good data throughput
for applications with high read request rates.
• RAID 6 (Disk striping with distributed parity across
two disks): Data is striped across all disks in the array
and two parity disks are used to provide protection
against the failure of up to two physical disks. In each row
of data blocks, two sets of parity data are stored.
• RAID 10 (RAID 1 and RAID 0 in spanned arrays): RAID
10 uses mirrored pairs of disks to provide complete data
redundancy. RAID 10 provides high data throughput
rates.
• RAID 50 (RAID 5 and RAID 0 in spanned arrays): RAID
50 uses both parity and disk striping across multiple disks
to provide complete data redundancy. RAID 50 provides
high data throughput rates.
• RAID 60 (RAID 6 and RAID 0 in spanned arrays): RAID
60 uses both distributed parity across two parity disks and
disk striping across multiple disks to provide complete
data redundancy. RAID 60 provides high fault tolerance.

SUPPORTED RAID LEVELS
The SAS 8888ELP RAID Controller 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
